Does the new ID field in the the ChaincodeOpPayload mean that the result of an invoke will be saved somewhere for polling or even sent back to the client on an event bus that is unique to that peer? I.e. that we can communicate real error info back to clients asynchronously?
Also, the ID is a JSON number, which is float64 in Go, so will there be an ID service that generates unique IDs on the peer? Or will we be expected to use some form of counter on a system for all apps to generate IDs? Was a GUID (e.g. time plus MAC address UUID) considered too large for this purpose?

ok so i wasn't at the f2f and i am sure my questions were most likely asked there... I've finally started the fabric build and i can't get my head around why the setup chain has its elements... i mean, aren't vagrant, docker and virtual box all geared towards providing the same start environment for a build? I've stared at the diagram for a while but i can't see why we have a vm in vagrant...
simon
2016-04-07 11:38
:simple_smile:
simon
2016-04-07 11:38
vagrant is used to provide a consistent, working development environment
simon
2016-04-07 11:38
vagrant uses virtualbox for this purpose
simon
2016-04-07 11:39
docker is used by fabric to execute chaincode processes
simon
2016-04-07 11:39
docker is also used during fabric development to easily spin up multiple instances of fabric peers to create a local network
simon
2016-04-07 11:39
does that help?
ghaskins
2016-04-07 11:59
@primrose: to add additional color to what @simon said: it is true that vagrant and docker both have overlapping goals in some sense (e.g. “repeatable” environments derived from a base image + devops orchestration file), but they are used for different purposes within the HL architecture
ghaskins
2016-04-07 12:02
for instance, docker has very specific requirements about the host (it has to be running a linux kernel, for instance)….even docker itself utilizes HV virtualization for this reason on non-linux platforms
ghaskins
2016-04-07 12:03
so vagrant+virtualbox get you a base linux environment that is suitable for hosting docker containers as well as providing other resources useful to building/running the fabric, and docker brings additional lightweight containers useful for things like chaincode isolation and network simulation
primrose
2016-04-07 12:11
@simon @ghaskins thank you!!! so vagrant+virtual box go together. got that. vagrant + vbox create the dev env whilst docker provides testing potential. with the added benefit that vagrant+vbox provide a "safe" initial machine for the docker bots (if i may call them that) to run in. is that right?
ghaskins
2016-04-07 12:12
yes, except I wouldnt limit docker role to just testing: it is currently used in a live environment too for chaincode isolation
ghaskins
2016-04-07 12:12
but otherwise, yes
ghaskins
2016-04-07 12:13
IOW, if you issue a “chaincode deploy”, it gets injected into a new docker container on each validating peer on the fly
ghaskins
2016-04-07 12:13
this would be true even for production
primrose
2016-04-07 12:14
@ghaskins ah i was googling what chaincode isolation actually meant. i get it now!
ghaskins
2016-04-07 12:14
cool
primrose
2016-04-07 12:18
i can't find a reaction which indicates that i'll sleep slightly less dumb tonight. but would you also be able to say why go needs to be installed on the host machine please? i would have thought this would only be needed in the VMs/Docker which are actually building and running the code?
ghaskins
2016-04-07 12:19
we are currently using go 1.6, though note you only need go on the host if you plan to edit/build there
ghaskins
2016-04-07 12:19
which is fairly common, but not strictly required
ghaskins
2016-04-07 12:19
at least, editing and building within an IDE
simon
2016-04-07 12:20
i think you need go only in the base docker image for chaincode
ghaskins
2016-04-07 12:20
@simon: i think @primrose is asking about the host environment itself
primrose
2016-04-07 12:21
@ghaskins: @simon yes the question was about the host env itself. the instructions ask for an install of go before all the VMs/Containers are setup and i wondered why
ghaskins
2016-04-07 12:21
@primose, i missed that you said “why” not “which”, which is why I said 1.6
ghaskins
2016-04-07 12:21
the why is to permit the user to edit the code in an environment that is most comfortable for them
primrose
2016-04-07 12:21
@ghaskins: i mistyped and corrected. mea culpa
ghaskins
2016-04-07 12:21
ah, that explains it
primrose
2016-04-07 12:22
i thought i was fast enough for it to be a seamless change!
ghaskins
2016-04-07 12:22
the basic idea is that the vagrant environment has all the stuff you need to build/run the code, but not necessarily all encompassing for editing
primrose
2016-04-07 12:22
+kudos to whoever put the setup together and made it so simple to run
primrose
2016-04-07 12:23
@ghaskins: got it. thanks! now i have to go and do something with the build...
vipinb
2016-04-07 12:39
There was talk at f2f about not requiring chaincode isolation as an alternative. So that known chaincode runs bound to the peer. This would be in addition to the current chaincode sandbox in docker
simon
2016-04-07 12:41
hi vipinb!
ghaskins
2016-04-07 12:44
@vipinb: i believe I have heard that called “system chaincode”, i think its under development
ghaskins
2016-04-07 12:45
theres also talk of making the isolation mechanism pluggable
vipinb
2016-04-07 12:49
Hello @simon my regards to Zurich
simon
2016-04-07 12:50
ghaskins: system chaincode is separate
simon
2016-04-07 12:50
system chaincode is administration/configuration
simon
2016-04-07 12:50
vipinb is talking about e.g. taking the blockstream/DAH code and linking it directly with fabric, instead of running it in a docker instance
simon
2016-04-07 12:51
of course you wouldn't deploy that code then
vipinb
2016-04-07 12:58
@simon . Just having the isolation mechanism pluggable like @ghaskins said. Which is having an option to have chaincode interpreter only, directly executable in peer/consensus context much like BTC. Of course only trusted/limited primitives will be allowed unlike the extensibility of docker contained chaincode. This was for speed and ease of deployment. Worth thinking about.
tuand
2016-04-07 13:08
, a reminder that with PR #1004 being merged overnight, the consensus config vars have been renamed from OPENCHAIN_OBCPBFT_xxxx to CORE_PBFT_xxxx and that CORE_PEER_VALIDATOR_CONSENSUS=pbft
tuand
2016-04-07 13:08
i've modified all the .yaml files as well but you might have some private configs that you'll have to update

@vipinb: when you say "chaincode runs bound to the peer" do you mean that the chaincode can not be updated on that peer once it has spun up? if so then i do not understand the pluggable mechanism... what would be the point of lightweight interpretation then?

@simon: part of the conversation about system chaincode is that it would have access to resources/facilities that are normally isolated, so it reminded me of what @vipinb was talking about
simon
2016-04-07 13:43
yes
simon
2016-04-07 13:43
related
ghaskins
2016-04-07 13:44
ok
ghaskins
2016-04-07 13:45
there does seem to be a conflation of issues/concepts in this thread:
ghaskins
2016-04-07 13:46
one issue would be the notion of some chaincode that has enhanced priviledges/access, and another for alternate chaincode environments/interpreters
ghaskins
2016-04-07 13:46
i see them generally as orthogonal
simon
2016-04-07 13:47
system chaincode is not chaincode itself, it just uses the same mechanisms to maintain configuration state of the peers
simon
2016-04-07 13:47
yes, they are
ghaskins
2016-04-07 13:47
agreed
simon
2016-04-07 13:47
they have a common aspect: they don't run in a docker container :simple_smile:
ghaskins
2016-04-07 13:47
I see “system chaincode” as something that looks/acts like chaincode as far as the outside worlds is concerned: you can send it invokes and it can submit mutated state to consensus, for instance
ghaskins
2016-04-07 13:48
but implementation wise, it would probably be .go code compiled into the fabric binary
ghaskins
2016-04-07 13:48
there are other ways to do it too, that is just one idea
kletkeman
2016-04-07 13:49
re: vagrant and docker ... the very first search result for "vagrant vs docker" brings up http://stackoverflow.com/questions/16647069/should-i-use-vagrant-or-docker-for-creating-an-isolated-environment, which answered the question for me nicely when I first started playing with this environment ...
ghaskins
2016-04-07 13:50
@simon: an astute observation, yes
kletkeman
2016-04-07 13:52
-- re my question yesterday, I noticed a conversation today (on an issue I think) discussing client subscriptions and actual results of invokes being sent back. The discussion was of course around the question as to what happens when the network loses track of a transaction. Anyway, is this feature imminent?

@ghaskins @vipinb @simon I think of it as “in process” chaincode with “system chaincode” as an instantiation of it. Helps separate out “system chaincode” specific concerns from the general chaincode specific functions. It also allows possibilities of non-system “in process” chaincode. And help to not take short cuts in the design/implementation …. break off from the current “container chaincode” design only where applicable.
simon
2016-04-07 14:58
right
ghaskins
2016-04-07 14:59
I cant think of where that distinction is important, but I am open minded to the possibility that it is
ghaskins
2016-04-07 15:01
to put it another way: running in process is one convenient way to implement “system chaincode”, but I cant think of a reason to want to run unstrusted code outside of isolation
ghaskins
2016-04-07 15:01
performance maybe? not sure
muralisr
2016-04-07 15:04
performance, maybe.… or policies ? system chaincode are given more rights
ghaskins
2016-04-07 15:04
I am all for well defined abstractions, of course, just not seeing where you would have code that doesn’t need enhanced privilege that you might want to run non-isolated
simon
2016-04-07 15:05
well, trusted code
ghaskins
2016-04-07 15:05
generally speaking, i think abstracting the chaincode environment such that it supports: system/priviledged chaincode, normal isolated chaincode (with choice on isolation vehicle), and, if desired, “in-process, untrusted” chaincode, that its a good thing
ghaskins
2016-04-07 15:06
even if the latter is never realized
simon
2016-04-07 15:06
for example, if DAH only wants to run a UTXO processor
simon
2016-04-07 15:06
why go through the hassle of adding all this docker complexity
ghaskins
2016-04-07 15:06
@simon: ah, now I see where the value is
ghaskins
2016-04-07 15:06
thank you, that is a good explaination
ghaskins
2016-04-07 15:07
so its not that its “untrusted”, its that certain use cases arent going to have users submitting chaincode
muralisr
2016-04-07 15:07
right
ghaskins
2016-04-07 15:07
got it, makes sense
muralisr
2016-04-07 15:08
right, tight, purposed environments
muralisr
2016-04-07 15:09
(can I say “purposed” ? :-))
ghaskins
2016-04-07 15:09
parses fine for me
ghaskins
2016-04-07 15:10
so, hyperledger/fabric as a platform for decentralized applications with state mutation goverened by consensus, where applications might be baked in, user submitted, or anything in between
ghaskins
2016-04-07 15:11
makes sense to me
simon
2016-04-07 15:11
well in the end, system state may have to be signed by a quorum of participants
ghaskins
2016-04-07 15:11
@simon: absolutely
simon
2016-04-07 15:11
not just automatically processed, but deliberately (policy) agreed to
simon
2016-04-07 15:12
do you have a suggestion on how to implement such a condition?
ghaskins
2016-04-07 15:12
if done right, the differences between system/in-process/untrusted should be handled the same w.r.t. consensus
simon
2016-04-07 15:12
more chaincode implementing this check?
ghaskins
2016-04-07 15:13
i envision that they look/act like any chaincode, they have an address, they can accept invokes/queries, and they can mutate Get/Put state which then goes through consensus
ghaskins
2016-04-07 15:13
the difference is really how they were deployed, thats it
ghaskins
2016-04-07 15:14
I envision that something like system/in-process is deployed via yaml, essentally consensus by common configuration
ghaskins
2016-04-07 15:15
something like untrusted is deployed as the mutation of state of a system chaincode that handles untrusted deployments
ghaskins
2016-04-07 15:15
where policy like AAA can be enforced in the system “deployment” chaincode
muralisr
2016-04-07 15:20
^ aligns with my thoughts… with the understanding some features (such as AAA) will be phased in
simon
2016-04-07 15:20
but that's my point: authorization policies will differ
muralisr
2016-04-07 15:22
dont understand that, simon...
simon
2016-04-07 15:22
muralisr: let's say you want to add validators to the system
simon
2016-04-07 15:23
this is something that cannot be decided unilaterally, but has to be performed by real-world agreements
ghaskins
2016-04-07 15:23
@simon: my thought there is through a combination of knobs on the “deployment” service, coupled with the fact that a network may opt to replace it with something else, you would achieve whatever policy you want
ghaskins
2016-04-07 15:23
network X might decide to configure yaml/genesis as [A,B,C], network Y, something else
simon
2016-04-07 15:23
so there needs to be a structure in place that prevents automatic change of the memberlist, unless certain real-world conditions are met
simon
2016-04-07 15:24
but, these conditions will be different for different deployments
simon
2016-04-07 15:24
therefore, how are these conditions formulated?
ghaskins
2016-04-07 15:24
those choices for yaml/genesis define what policies are in place for subsequent mutations
ghaskins
2016-04-07 15:25
and the consensus at this level is simply that the network is configured with a compatible yaml/genesis
simon
2016-04-07 15:25
so you're saying there is a limited set of policies you can choose from, and you might be able to parametrize those
ghaskins
2016-04-07 15:26
what I am saying is, the policies have a root in the initial configuration of the network
simon
2016-04-07 15:26
sure
ghaskins
2016-04-07 15:26
which is a combination of configuration+genesis block
simon
2016-04-07 15:26
i'm asking: how are these policies implemented
ghaskins
2016-04-07 15:26
ok, lets say we had a system chaincode for deploying other chaincode
ghaskins
2016-04-07 15:27
the only way to get untrusted code in the system is to send a “deploy” invoke to the system chaincode address for the deployment service
ghaskins
2016-04-07 15:27
that code is responsible for implementing the policy of who/what/where/whatever on what consistutes a valid deploy transaction
simon
2016-04-07 15:27
okay
simon
2016-04-07 15:28
so write go code
ghaskins
2016-04-07 15:28
some of that policy might be driven by yaml knobs, some of that policy might be baked in to the go code
ghaskins
2016-04-07 15:28
if an operator likes the reference implementation of the deployment service, they deploy it with the knobs they want
ghaskins
2016-04-07 15:28
if they dont, they omit/replace it with an alternate system chaincode
simon
2016-04-07 15:29
would that system chaincode run in a docker container?
ghaskins
2016-04-07 15:29
i dont envision that, no
simon
2016-04-07 15:29
that means that the peer needs to be built locally
kelly
2016-04-07 15:29
@ghaskins and @simon I think that is a good idea
ghaskins
2016-04-07 15:30
I think like I said before, there is the concept of an abstract chaincode endpoint that looks/acts like chaincode, it has an address, it can accept transactions, it can submit mutated state to consensus
kelly
2016-04-07 15:30
Today, for example, you can't run docker's in a trusted execution evironment
ghaskins
2016-04-07 15:30
but the environment that a system chaincode runs in is likely completely different from an untrusted chaincode
ghaskins
2016-04-07 15:30
it is likely something just compiled into the fabric
simon
2016-04-07 15:30
uh oh
ghaskins
2016-04-07 15:31
why “uh oh”?
simon
2016-04-07 15:31
requiring admins all over the world to compile their binaries in exactly the same way...
ghaskins
2016-04-07 15:31
its not really different than deciding what your yaml/genesis are, right? code base selection is part of that criteria
simon
2016-04-07 15:31
genesis is fixed via cryptographic hash
ghaskins
2016-04-07 15:31
while that is a perfectly valid model, I envision it would be more like a release
ghaskins
2016-04-07 15:32
no, it isnt :wink:
ghaskins
2016-04-07 15:32
genesis is “fixed” by what the network of nodes agrees its value is out of band from the fabric
simon
2016-04-07 15:32
yes, by means of a cryptographic hash
simon
2016-04-07 15:33
no shared genesis hash = not part of same chain
simon
2016-04-07 15:33
more difficult with compiled code
ghaskins
2016-04-07 15:34
otp
simon
2016-04-07 15:34
i was thinking that maybe some form of language expressing the authorization criteria could be used, and a program of this language (script) be part of the genesis block
sheehan
2016-04-07 15:35
@simon: "requiring admins all over the world to compile their binaries in exactly the same way…”
I haven’t looked into it yet, but I was pointed to https://gitian.org/ the other day. It may be worth looking into
simon
2016-04-07 15:36
fancy
simon

but one binary, signed by a trusted entity - far simpler

i suppose

to me the whole point of a blockchain is for the trust to be built into the system itself... i didn't think of the build elements but it sounds weird to make an exception of them
simon
2016-04-07 15:55
well, this is where you transition from network to individual
simon
2016-04-07 15:56
your local admin always has power over your systems

@simon: back
ghaskins
2016-04-07 16:35
I think no matter how you slice it, there is extrinsic agreement, and there is intrinsic agreement
ghaskins
2016-04-07 16:35
extrinsic agreement would be things like the choice of software/configuration/genesis
ghaskins
2016-04-07 16:36
whether that means there is one “http://myblockchain.com” that you download a package that has the software/configuration/genesis that all operators trust/use, or some other mechanism doesnt matter
ghaskins
2016-04-07 16:36
at least, conceptually
ghaskins
2016-04-07 16:37
some other mechanism might be a conference call where the parties agree on the git sha and yaml contents and then go off and build it themselves, it doesnt matter
simon
2016-04-07 16:37
conceptually correct, practically maybe difficult?
ghaskins
2016-04-07 16:37
i am not advocating one vs the other
ghaskins
2016-04-07 16:37
i am just saying, that extrinsic agreement needs to exist
simon
2016-04-07 16:37
i'm strongly advocating for correct by design
simon
2016-04-07 16:38
meaning, the extrinsic agreement is required anyhow (people installing the same thing), but the system should prevent incorrect operation
ghaskins
2016-04-07 16:38
and it is via this mechanism that establishes policy, such as what the deploy-system-chaincode does
simon
2016-04-07 16:38
oh, and fail early
ghaskins
2016-04-07 16:39
and it would: if people didnt establish the extrinsic agreement, the network probably would never converge, or be able to achieve consensus, etc
ghaskins
2016-04-07 16:39
but that isnt really my point
simon
2016-04-07 16:39
don't fail when you try to update your policy on how to deploy new chaincodes, because it turns out different nodes are configured differently
ghaskins
2016-04-07 16:39
my point is that it is the extrinsic agreement that establishes the policy that governs the intrinsic behavior
simon
2016-04-07 16:40
sure
simon
2016-04-07 16:40
i think we agree in principle?
ghaskins
2016-04-07 16:40
i think so
simon
2016-04-07 16:42
my point was that the system should check that all nodes are configured the same way (due to extrinsic agreement)
simon
2016-04-07 16:43
policy as implemented in the code: difficult to check (different platforms mean different binary, etc.)
simon
2016-04-07 16:43
policy implemented e.g. as a script (i.e. interpreted rules): easier to test, can even be part of the genesis block
ghaskins
2016-04-07 16:46
oh sure, i agree with you on that
simon
2016-04-07 16:46
great!
ghaskins
2016-04-07 16:47
at least in terms of making it easier
ghaskins
2016-04-07 16:47
not necessarily in how to make it easier
ghaskins
2016-04-07 16:47
i have no strong opinion on that
simon
2016-04-07 16:47
yea i don't know what the best is
simon
2016-04-07 16:47
i guess bitcoin script is a strong precedent
ghaskins
2016-04-07 16:48
i think the most important thing is, a mismatch is likely to already be handled (e.g. membership list disparity would prevent quorum from forming, or the EV checks on system chaincode mutations wont match, failing to commit its transactions, etc
simon
2016-04-07 16:49
if we design it carefully
simon
2016-04-07 16:49
and there are no bugs, etc.
ghaskins
2016-04-07 16:49
but, having it say “hey, your network is mismatched” is a better behavior than just failing to every get a convergence
simon
2016-04-07 16:49
yes
simon
2016-04-07 16:49
better stop the network than keeping operating under inconsistency
ghaskins
2016-04-07 16:49
right
ghaskins
2016-04-07 16:50
it would need to be carefully thought out too, though
ghaskins
2016-04-07 16:50
as disparity doesnt always mean incompatiblity
ghaskins
2016-04-07 16:50
for instance, older vs newer releases running together
ghaskins
2016-04-07 16:50
the main criterial is the protocol can operate in agreement

@primrose: Our experiment with writing a chaincode is https://github.com/stanliberman/obc-peer/tree/master/openchain/example/chaincode/asset_manager it’s now out of date with the new fabric codebase. It should still work once corrected for new names. Wiki has excellent instructions on getting things running and you can read through our scripts for more user level interaction.

There’s an event_test at https://github.com/hyperledger/fabric/blob/master/events/events_test.go
This allows you to listen to block events from the chain. Sending events from within a chaincode is not recommended because
1 - The chaincode will be run by multiple peers
2 - Just because code in a chaincode was invoked on a given peer does not guarantee the changes will be in a block
novusopt

How do I obtain chaincodeID.name value after the deploy ?
muralisr
2016-04-19 04:44
@ibmamnt: there is no easy way to do that today. You can get transactions from a block, unmarshal with code etc. which clearly is not desirable. There is discussion of a naming service which when implemented will solve naming issues
ibmamnt
2016-04-19 04:57
@muralisr: Thanks for the answer. In a debug mode, I can put arbitrary name via CORE_CHAINCODE_ID_NAME env. So obtaining name is not high priority at this moment.

In the protocol specification you are saying (chapter https://github.com/hyperledger/fabric/blob/master/docs/protocol-spec.md#4321-confidentiality-against-users) "Finally users are given the contract's public key PKc, for them to be able to encrypt information related to that contract for the validators (or any in possession of SKc) to be able to read it. Transaction certificate of each contract user is appended to the transaction and follows that user's message....."
novusopt
2016-04-19 14:21
how do you distribute the public key of the contract (PKc) to the involved users?

I read about the CertificateHandler interface in the section 4.4.1 Invocation access control which supposedly allows you to sign and verify messages
mcrafols

but as @novusopt I had the same question on who manages the user's certificates and how the application (for example Marbles) could access it to sign and verify signatures
novusopt
2016-04-19 14:38
@mcrafols: the section 4.4.1 explains how to implement an own access control at the application layer...
mcrafols
2016-04-19 14:39
@novusopt: but it says:
mcrafols
2016-04-19 14:39
The client-application can request the fabric to sign and verify any message with specific transaction certificates or enrollment certificate the client owns; this is expressed via the Certificate Handler interface
novusopt
2016-04-19 14:40
@mcrafols: my question is after i created a chaincode and i specified an ACL, how does the fabric distribute the public key of the chaincode to the users specified in the ACL
novusopt
2016-04-19 14:43
without customizing the invocation access control
mcrafols
2016-04-19 14:52

@mcrafols: didnt understand my question?
mcrafols

Hi @novusopt, sorry if the paragraph is not clear enough. Actually, the deployer can specify in the deploy transaction who is able to invoke the chaincode he is deploying. If you look at the picture in that same paragraph, there is a section called "contract users".
adc
2016-04-19 16:26
In that section the deployer has to name of who can invoke the chaincode, the recipient, by specifying one of the TCert of the recipient. The deployer will also encrypt pkC under the public key of the recipient.
adc
2016-04-19 16:27
Once the recipient gets the deploy transaction in some way, he can figure out that he has been named there and retrieve pkC that can used to encrypt the invoke/execute transaction payload
adc
2016-04-19 16:27
Access control is a different story. I can give more details on that too if needed.
novusopt
2016-04-19 16:37
@adc: first of all thank u for the information! You mentoined that the users can figure out that they have been named, how does the fabric handle this?

After I got error, I read through the document. And understood fully about ":latest" is not used in Hyperledger project. By the way, docker image is now runnning after /chaincode/deploy restapi call. I now understand chaincode.name is included in docker container image ( previously I raised a question how to find chaincodeID.name). Now, I can invoke restapis even if I forget the respose.

As of 2016/April/20th, Golang is supported by Hyperledger fabric project. According to FAQ, JavaScript and Java support is planned within 2016.

cool is there funding up for grabs to get that implemented? i already know some cases where people would love to present their smart contracts to judges and jury but can't cause they're not in javascript

@novusopt, there are multiple ways to get the deploy transaction. One is through an off-band channel (i.e. on a certain web site there is the chaincode id of the deploy transaction). Another one could be through a trusted third party that monitor the blockchain on you behalf and collects the deploy transactions where you are named. We are also looking into other alternatives to make this process as simple and intuitive as possible :simple_smile:
novusopt
2016-04-20 07:00
@adc yes that make sense, thank u :simple_smile: so that means currently the fabric does not notify the involved users?
adc
2016-04-20 07:08
@novusopt, yes, it is correct.

with the Latest commit 488d266 issue #1131 — moving main.go to fabric/peer. You may encounter the problem in vagrant:
```vagrant@hyperledger-devenv:v0.0.9-2457c97:/opt/gopath/src/github.com/hyperledger/fabric$ cd peer/
-bash: cd: peer/: Not a directory```
It seems vagrant caches the `peer` exe file. The solution is to run:
```vagrant halt
vagrant up
```

To implement an ACL into the invocation methods the application layer must use CertificateHandler? How can the application access the CertificateHandler to sign the invocation?
adc
2016-04-20 14:34
@mcrafols: Actually a CertificateHandler and a TransactionHandler are needed as described here https://github.com/hyperledger/fabric/blob/master/docs/tech/application-ACL.md
adc
2016-04-20 14:35
How the application can access these structures is more trickier. We are exactly working on this to make the API accessible in a secure way to the application. In the meantime, you can have a look at here https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management
adc
2016-04-20 14:36
it contains an example (code) of how to implement access control at the chaincode level
mcrafols
2016-04-20 14:37
I see, the API access is what I was missing
mcrafols
2016-04-20 14:37
because the user ECerts are stored in the trusted VP right? For the ChainCode to access the public keys of other user's certificates you need to connect the ChainCode to the CA?
mcrafols
2016-04-20 14:52
and how is the user ECert accessed from the application, is it possible currently?
adc
2016-04-20 15:17
@mcrafols: Q1: yes, Q2: actually the chaincode stores the ECert/TCert in its state
adc
2016-04-20 15:18
the ECert can be accessed via REST api but anyway we are actively working on the client SDK that will allow to orchestrate the chaincodes
mcrafols
2016-04-20 15:21
@adc: oh I see: GET /registrar/{enrollmentID}/ecert retrieves the Ecert from the trusted VP not the CA?

Question about environmental variable. I believe config file and environmental variable handling is done by "viper". The setting file "core.yml" has cascade, like:
```peer:
id: jdoe
networkId: dev
addressAutoDetect: false
port: 30303
gomaxprocs: -1
workers: 2
validator:
enabled: true```
ibmamnt
2016-04-21 05:48
If I want change the peer functionality as non-validating peer by environmental variable, CORE_ prefixed like:
```CORE_PEER_VALIDATOR_ENABLED=false```
is valid setting. Is this understanding correct ?

jeffgarratt
2016-04-21 13:47
you can actually load this into the swagger UI and it will dynamically generate REST calls for you

muralisr

@ghaskins: trying to do a “in a nutshell” of “chaintool” : An end user writing chaincode can describe it in highlevel protobuf structure and chaintool will generate (1) the chaincode with appropriate methods stub and (2) package it for the user so it can be directly deployed … please do change as you see fit ?

@novusopt: You can specify the number of buckets in core.yaml using the numBuckets property. Keys are evenly distributed between these buckets

@ibmamnt: FYI, here is the fabric side support for the tool: https://github.com/ghaskins/hyperledger-fabric/tree/chaintool-snapshot-20160422-1729
ghaskins
2016-04-22 21:35
It seems you are not using vagrant, so you would have to handle getting the chaintool on your $PATH manually
ghaskins
2016-04-22 21:35
I include the binary in ./devenv/tools FWIW, or you can just build it from source
novusopt
2016-04-22 22:00
@sheehan: correct me if i am wrong, but that means once i deployed my blockchain with the bucket configuration i am limited to the number of buckets which means the max nbr of states of all chaincodes?
sheehan
2016-04-22 22:01
the bucket configuration cannot be changed after the blockchain is deployed, but this imposes no limit on the number of states of all chaincodes. Each bucket can hold multiple keys and keys from different chaincodes can potentially live in a single bucket.
novusopt
2016-04-22 22:03

I noticed about new client sdk (node.js) via
> Merge pull request #1187 from angrbrd/client_sdk
Looks like current implementation is for member services, but I also see some code related to chaincode Invoke/Query. I suspect this module might include most of peer rest api in the near future. Is this correct ? Not sure if Angry Bird monitor this channel or not. I also think we should remove Bluemix things (or make it Cloud Foundry and Docker aware module as cloud native app.

My concern is that whether this a correct way of communicating with the fabric?
mcrafols
2016-04-25 13:28
I am not fully certain but I think that in this case you might want to use the REST API
mcrafols
2016-04-25 13:28
POST host:port/chaincode for instance
mcrafols
2016-04-25 13:29
being host the address of you VP and port is usually by default 5000
karthik
2016-04-25 13:35
This is a ajax call right. Can you give a example of this POST request?

look for REST Endpoints in the link you posted
karthik
2016-04-25 13:45
OK , for example for the invole function - /devops/deploy needs to be used. could you give me an example like:- $.ajax({url: http://127.0.01:5000/devops/deploy/, data:data, type:POST}).

2016-04-25 15:26

ghaskins
2016-04-25 15:59
@keithsmith: sorry, was on the phone
ghaskins
2016-04-25 16:00
my primary question is: is it usable as checked in to the HL repo? I tried it but got an exception from simply the require(‘hlc’)
ghaskins
2016-04-25 16:00
i suspect I am just not using it properly (I am not a nodejs guy)
ghaskins
2016-04-25 16:01
but I was curious if it was expected to work (at least to the level that test.js calls it) or is it just there as a preview
ghaskins
2016-04-25 16:01
i think part of the problem is that its not in npmjs yet, so I am not sure if I declared the dep properly in the package.json
ghaskins
2016-04-25 16:02
it seems transitive deps like grpc were not being found so the require blows up…like I said on the OBC slack, i suspect its 99% operator error on my part
ghaskins
2016-04-25 16:04
@ghaskins uploaded a file: https://hyperledgerproject.slack.com/files/ghaskins/F13FUD5UG/-.txt and commented: I was including it by path explicitly since its not in npmjs yet…I can see that npm-install does pull it locally into my node_modules but for some reason the transitives are not visible to the runtime

ghaskins
2016-04-25 16:22

ghaskins
2016-04-25 16:23
e.g. I see my-app/node_modules/hlc/node_modules/grpc
ghaskins
2016-04-25 16:23
and when I require(‘hlc’) its blowing up b/c it doesnt see grpc
ghaskins
2016-04-25 16:23
is this typically how it works (nested like that)?

-- A quick question re NVP's and world state. After reviewing the protocol spec in great depth, and visiting every reference to non-validating or state, I cannot find out whether the NVP maintains a copy of the world state in addition to its copy of the blockchain. The reason I ask is that it would be very useful to deploy an NVP whose sole job it to service complex state queries for lightweight analytical purposes. But if NVPs don't have world state, then their usefulness would drop quite a bit I think ... (still nice to have NVPs handle apps and events, but not nearly as useful of taking the queries out of the VPs in very active systems) ...
simon
2016-04-25 16:39
i don't think that we really use NVPs at the moment
kletkeman
2016-04-25 16:39
we do
simon
2016-04-25 16:39
ah!
kletkeman
2016-04-25 16:39
as application gateways
simon
2016-04-25 16:39
it will not be able to maintain world state for confidential chaincode
kletkeman
2016-04-25 16:42
it is my understanding that the NVP is a subset of the VP, so would it not have the confidentiality code as well?
kletkeman
2016-04-25 16:42
but more importantly, since NVPs do not execute transaction, they would need to replicate world state from their connected VPs ...
kletkeman
2016-04-25 16:44
also, re security, we envision NVPs living inside corporate firewalls in some instances and thus having implicit security ... perhaps it should be possible to configure such an NVP with a default security level ...

@ibmamnt: fyi, i notice a bug in the chaintool code generator today (https://github.com/ghaskins/chaintool/commit/960696dbcbdea2df9aaa87c906936d1fee7e1406), ill cut a v0.5.1 update to address this
jeffgarratt
2016-04-25 18:07
@simon: @muralisr wrt to nvp, I believe the current thinking is that state is NOT replicated to nvps, only the blocks. For now, I do not think even blocks are replicated as of yet.
simon
2016-04-25 18:07
right, that's what i thought
simon
2016-04-25 18:07
but you could as well
jeffgarratt
2016-04-25 18:08
yes, the parts are in place to support it
simon
2016-04-25 18:09
and right, an operator may configure their NVP with encryption keys so that the NVP can also read confidential state
kletkeman
2016-04-25 18:21
@jeffgarratt: thanks ... the protocol spec says that NVPs maintain a copy of the blockchain, but this is actually of less use than maintaining a copy of world state as application gateways would be tremendously useful for offloading state queries ... any chance that world state will eventually get copied to NVPs?
jeffgarratt
2016-04-25 18:23
@kletkeman: the current issue is that state is interpreted relative to chaincode, and queries today go through chaincode themselves.
jeffgarratt
2016-04-25 18:25
I don't think it is technically infeasible, but the form of the state values if chaincode dependent, ie. the state is simply bytes, and the reader of the state would need to have internal knowledge of the storage.
jeffgarratt
2016-04-25 18:25
basically, wrt to any chance question, yes. But I think we need to approach carefully wrt the privacy.
kletkeman
2016-04-25 18:27
@jeffgarratt: I have been labouring under the impression that the protocol spec says that NVPs are a proper subset of VPs for a reason ... as in they run chaincode (after VPs validate of course) for queries (but not invokes) and they maintain world state as replicated copies ... but if they don't run chaincode and they don't maintain state then they are a rather small subset of a VP ...
kletkeman
2016-04-25 18:29
i.e. I have been viewing NVPs as a VP without consensus rights
kletkeman
2016-04-25 18:29
but that was clearly way off base
jeffgarratt
2016-04-25 18:30
at least for the current implementation
jeffgarratt
2016-04-25 18:30
but I do not think your are far from the target
jeffgarratt
2016-04-25 18:30
wrt to your expectations
jeffgarratt
2016-04-25 18:31
and the specs statements :simple_smile:
kletkeman
2016-04-25 18:31
ah ... ok ... so I'm not hallucinating :simple_smile:
jeffgarratt
2016-04-25 18:31
no, well.... not wrt to this :simple_smile:
kletkeman
2016-04-25 18:32

mcrafols
2016-04-26 11:29
$GOPATH or $GOPATH/src

ghaskins
2016-04-26 11:30

it should really be benign if you are not using events…. ie, if you are having any other problem it’s likely not related to this error

its probably it because if I remove the CA everything works fine

I am trying to set up locally the marbles app and it probably uses events

but even if I don't use events, I cannot retrieve the information in the block where such chaincode is stored

(using the ...:5000/chain/blocks/1)
mcrafols
2016-04-27 11:16
@muralisr: is this related to the chaincode itself? Or it always happen if Privacy is enabled?
muralisr
2016-04-27 11:26
@mcrafols: the error itself happens when the system attempts to remove the large deployment image before sending it out as an event - and fails because of encryption. The event is still sent but with the large deployment image
muralisr
2016-04-27 11:29
If your deployment fails I’d expect other errors before the sendProducerBlockEvent error
mcrafols
2016-04-27 12:39
@muralisr: but then checking the blockchain through the REST API is considered an event?
muralisr
2016-04-27 12:40

@alex.oberhauser: you might be interested in Rootstock, which allows Ethereum contracts to be compiled directly into a Bitcoin-backed sidechain: http://www.rootstock.io/
kletkeman
2016-04-27 13:37
The documentation for Solidity (Ethereum's contract language with similarities to JS syntax) is at http://solidity.readthedocs.org/en/latest/introduction-to-smart-contracts.html#simple-smart-contract
Solidity contracts run on the Ethereum Virtual Machine and so there is the first major difference. Still, a lot of the basic facilities of EVM have parallels in Hyperledger I imagine.
Looking at the examples in those docs, it is pretty easy to see how one would transcribe from Solidity to Go, but of course these do not make use of the advanced features of EVM.

jzhang
2016-04-27 15:00
the behave tests seems to suggest that using the yaml files with docker-compose i should be able to contact the peers with paths like http://<ip>:<port/network/peers
simon
2016-04-27 15:01
yes, i think so

jzhang
2016-04-27 15:02
am i missing something?
jeffgarratt
2016-04-27 15:03
@jzhang: the ports are NOT exposed, rather you can refer to the peers with there dockerCompose service name
jeffgarratt
2016-04-27 15:03
from the behave tests themselves
jeffgarratt
2016-04-27 15:04
@jzhang: what are you trying to perform that you cannot, and perhaps I can help you or modify the system if there is a deficiency
jeffgarratt
2016-04-27 15:05
@jzhang: and you can refer to the docker-compose-default.yaml for the default port for all VPs

2016-04-27 15:05
so this step suggests that i should be able to contact the peer via http right?
jzhang
2016-04-27 15:06
looking at compose-defaults.yaml:
vp:

environment:
- CORE_PEER_ADDRESSAUTODETECT=true

# TODO: This is currently required due to BUG in variant logic based upon log level.
- CORE_LOGGING_LEVEL=DEBUG
command: peer peer
jzhang
2016-04-27 15:07
not sure what I should use as the port from the host to contact the peer
jeffgarratt
2016-04-27 15:07
sorry, the setting is default per peer.address setting to 0.0.0.0:30303
jeffgarratt
2016-04-27 15:07
that is the GRPC port
jeffgarratt
2016-04-27 15:07
the HTTP port is 5000

2016-04-27 15:07

Where should I give some feedback on Hyperledger fabric ? Is this good channel ? For example, I invoke a chaincode to do some transaction, and then immediately query on worldstate gives me this error:
```Query chaincode result: {"jsonrpc":"2.0","error":{"code":-32003,"message":"Query failure","data":"Error when querying chaincode: Error:Failed to launch chaincode spec(Could not get deployment transaction for f94be74d5e8eaa1771642831198cf460486457ce96d765b552613040d4c095514c3dbb73c9d2c3fb743de570af8d463dcafb56683d3f32c4a49d597cea2676ad - ledger: resource not found)"},"id":5}```
Or do we have any list of error code ? The purpose is to develop front end application such that it knows about the status of transaction, and UI can show like "Processing transaction, please try later ..." or something like this.

i feel the command ./peer peer is strange, why not just use. /peer run or ./peer start

@grapebaba: you’re not the only one :simple_smile: discussion at https://github.com/hyperledger/fabric/issues/1158

Was just reviewing unrelated code when I noticed this: https://github.com/hyperledger/fabric/blob/master/core/chaincode/config.go#L77
ghaskins
2016-05-01 12:00
shouldn’t that be runtime.GOMAXPROCS(numProcsDesired)?
ghaskins
2016-05-01 12:01
that pattern repeats a few times too, fwiw

hey -- is anyone from IBM working on packaging for Fabric? If so, who would that be?
simon
2016-05-02 12:23
what do you mean by packaging?
simon
2016-05-02 12:23
rpm/deb stuff?
simon
2016-05-02 12:24
I don't think this is being worked on
tuand

@simon yep, that. @bmos299 do you know if anyone is working on packaging for Fabric?
sheehan
2016-05-02 12:52
@jeremyeder: @ghaskins: (not from IBM) has been the lead committer in this area. I don’t think he has investigated packaging the fabric, but he has looked into packaging some of its dependencies. He also did most of the base image work. https://github.com/hyperledger/fabric/tree/master/devenv/baseimage
You’ll want to get his advice/input for any packaging work
sheehan
2016-05-02 12:54
ah, see you already connected on the mailing list :simple_smile:

jeremyeder

ah, hey @ghaskins how are you
ghaskins
2016-05-02 14:06
good thanks
ghaskins
2016-05-02 14:06
speaking of packaging, that effort I mentioned was my first foray into launchpad based packaging…prior to that I was using the opensuse build service
ghaskins
2016-05-02 14:07
i wasnt a huge fan of the way the launchpad service worked in comparison to the suse engine, but seeing you work for RH perhaps there is a third option to consider?
jeremyeder
2016-05-02 14:07
@ghaskins: great -- ah yeah, you'll have to excuse me, i am not familiar with PPA etc
ghaskins
2016-05-02 14:08
that rocks packaging was my first time really using it myself
ghaskins
2016-05-02 14:08
ive done a ton of packaging work under the suse engine, that was just my first time using launchpad
ghaskins
2016-05-02 14:09
I just saw your renaming question: yes that is indeed the intent
jeremyeder
2016-05-02 14:10
@ghaskins: yeah as you can imagine. fedora, centos, rhel have equivalents
ghaskins
2016-05-02 14:10
the reason the docker side lagged is because I initially didnt have access to the “hyperledger” namespace in dockerhub
ghaskins
2016-05-02 14:10
but that was resolved a week or two ago, and its on my todo list
ghaskins
2016-05-02 14:10
yeah, i would imagine that is the case
jeremyeder
2016-05-02 14:11
@ghaskins: ah cool. do you have any interest in allowing a conditional somewhere in the packer stuff to allow for centos- or fedora-based build artifacts?
ghaskins
2016-05-02 14:11
i know the opensuse engine can generate artifacts for all the major distros, which is a nice feature I am not sure is replicated everywhere
ghaskins
2016-05-02 14:12
i personally maintain packages for RH/Suse/Ubuntu in there
ghaskins
2016-05-02 14:12
@jeremyeder: of course!
ghaskins
2016-05-02 14:12
if you have a proposal on how to integrate other platforms, i am totally open to that
ghaskins
2016-05-02 14:14
to be honest, i am not married to packer either….it was a proposal I made to try to unify vagrant+docker generation, but there might be other ways to achieve the same
jeremyeder
2016-05-02 14:14
yeah, same here wrt packer.
ghaskins
2016-05-02 14:14
i think the core requirement is to try to unify the generation of the images one way or the other from one source of truth
jeremyeder
2016-05-02 14:14
nod
ghaskins
2016-05-02 14:14
how we get there, i dont have a strong opinion as long as its reasonable
cbf
2016-05-02 14:14
@jeremyeder: we’d want to ensure that the CI incorporates alternate OS (and platform) builds (eg X, open power, Z/Linux, ARM, FPGA, etc)
jeremyeder
2016-05-02 14:15
@cbf: yep. understood. the challenge is that most distro build infras are not supporting all different packaging formats equally (probably why packer exists)
cbf
2016-05-02 14:16
d'accord
jeremyeder
2016-05-02 14:16
this is why i was questioning what the ultimate delivery mechanism will be for customers who want to use Fabric. will it be a container image or not.
cbf
2016-05-02 14:17
I would assume so
ghaskins
2016-05-02 14:17
thats def a question for @cbf etc…my motivation for involvement to date was w.r.t. reducing the overhead of iterative development builds
cbf
2016-05-02 14:17
certainly don’t see vagrant as being anything more than a convenience for developers
ghaskins
2016-05-02 14:17
not so much looking at production delivery vehicles (though I understand there can be a correlation/overlap)
ghaskins
2016-05-02 14:19
my guess is this will end up looking like other FOSS projects like openstack: there will be one upstream community supported platform and then the distros will package it up as appropriate for the different flavors
cbf
2016-05-02 14:20
@ghaskins: that’s in line with what I would hope we’d get to
ghaskins
2016-05-02 14:22
@jeremyeder: one task I have for the immediate future is to get the openblockchain/baseimage dockerhub available under hyperledger with additional provisions for $arch
ghaskins
2016-05-02 14:22
the current thought is this will be addressed with tags like :$arch-$version
jeremyeder
2016-05-02 14:22
@ghaskins: i see -- cool.
jeremyeder
2016-05-02 14:22
@cbf
jeremyeder
2016-05-02 14:22
woops.
ghaskins
2016-05-02 14:22
e.g. hyperledger/fabric-baseimage:x86_64-0.0.9
ghaskins
2016-05-02 14:23
then we can represent others like ppcle or s390 in a similar namespace
ghaskins
2016-05-02 14:23
but those would still be ubuntu, probably
ghaskins
2016-05-02 14:23
not sure how distro flavor might roll into that, input welcome
jeremyeder
2016-05-02 14:23
@cbf there are serveral assumptions being made in the existing devenv stack, im just seeing if i can wire in fedora/rhel in there.
ghaskins
2016-05-02 14:24
one question is: are you trying to get a RH base throughout (devenv and docker)? or just for the fabric environment
jeremyeder
2016-05-02 14:24
@ghaskins: right, and thats of course my question too :simple_smile:
cbf
2016-05-02 14:24
@jeremyeder: I’m all for having broader OS support
ghaskins
2016-05-02 14:25
to put it another way, do you need/care to have the docker be RH too, or is it ok as long as fabric can be deployed on RH
ghaskins
2016-05-02 14:25
(to be clear, i am not against either model, just trying to understand your goals)
jeremyeder
2016-05-02 14:25
@ghaskins: @cbf ahh. so first step is to just get openblockchain/baseimage deployed on openshift. ill do that today.
cbf
2016-05-02 14:26
:wink:
jeremyeder
2016-05-02 14:26
and then, as you can expect we would like to be considered as an option for the baseimage, with the version tags as you mentioned (there are several existing examples of this already)
ghaskins
2016-05-02 14:27
if you have some examples of how distro/arch things are handled within docker, pls share
cbf
2016-05-02 14:27
@jeremyeder: I think that it would be slick to demonstrate not just OS but k8s
jeremyeder
2016-05-02 14:27
nvidia does this for their cuda stack: docker pull nvidia/cuda:{centos,ubuntu}
cbf
2016-05-02 14:27
would assume there’s much overlap (if not complete)
ghaskins
2016-05-02 14:28
ah, so perhaps the tags should be like :$distro-$arch-$version ?
jeremyeder
2016-05-02 14:28
cbf: openshift is extremely close to k8s, id argue if it doesnt work on kube then its a bug
ghaskins
2016-05-02 14:29
i guess one question, particularly to @cbf and the TSC: would you like to see the “hyperledger” namespace reflect all distro variations as per above, or would we recommend it be handled as a sep namespace (ala “nvidia”)
ghaskins
2016-05-02 14:30
i could see it going either way
ghaskins
2016-05-02 14:30
it could be RH flavor of hyperledger references a different dockerhub (e.g. “redhat/*”)
cbf
2016-05-02 14:31
I think that all depends on who maintains the image, yes?
ghaskins
2016-05-02 14:31
my only thought is w.r.t. permissions/access to the hyperledger namespace, as well as potential crowding
ghaskins
2016-05-02 14:32
yes that is certainly true
jeremyeder
2016-05-02 14:33
well, red hat would maintain the fedora, centos and rhel images. but we would not maintain the Fabric image itself -- we would work that through our normal ISV partnership programs
jeremyeder
2016-05-02 14:35
ive been playing with this myself
jeremyeder
2016-05-02 14:35
i have a Dockerfile called c7perf on dockerhub which is based on the centos image. i just install a few extra tools on top of the centos image.
jeremyeder
2016-05-02 14:35
there are places for github hooks so when i change the c7perf Dockerfile in my github, dockerhub will rebuild c7perf image automatically
jeremyeder
2016-05-02 14:36
@ghaskins: what if we did somethins similar for Fabric -- when a Dockerfile is updated in the Master branch (or -stable?) then dockerhub rebuilds the image automatically?
jeremyeder
2016-05-02 14:36
@cbf
ghaskins
2016-05-02 14:37
@jeremyeder: thats probably tenable if integrated into some kind of CI trigger
jeremyeder
2016-05-02 14:37
yep, i guess when it sees a new "stable" tag
jeremyeder
2016-05-02 14:37
it == dockerhub
ghaskins
2016-05-02 14:37
right now, we only push the “baseimage” which changes infrequently based on the scripts under ./devenv/baseimage
ghaskins
2016-05-02 14:38
it could certainly be a trigger based on changes there, or whatever else is appropriate
ghaskins
2016-05-02 14:39
one problem that needs to be solved generally is version coupling
ghaskins
2016-05-02 14:39
right now, the notion that baseimage-v0.0.9 is current is spread out in a few different places
ghaskins
2016-05-02 14:40
the devenv/Vagrantfile and .travis.yml files come to mind, there may be others
ghaskins
2016-05-02 14:40
any time there is a new baseimage, we need to push the images out to atlas (vagrant) and dockerhub, and then update those two files
ghaskins
2016-05-02 14:41
the notion of rolling forward to a new release would have to unify and/or incorporate that notion
ghaskins
2016-05-02 14:42
not specifically related to your CI-based proposal, but I would love it if at least the definition were in one place (e.g. “./version.dat”) that the Vagrantfile and travis (and anything else that needed it) could draw from
jeremyeder
2016-05-02 14:43
oh
jeremyeder
2016-05-02 14:43
thats got to be taken from the fabric code somewhere, like a github tag, no?
ghaskins
2016-05-02 14:43
well, thats a different matter
ghaskins
2016-05-02 14:44
we _need_ to be creating github tags for the baseimage releases, but to date have not
jeremyeder
2016-05-02 14:44
oh
ghaskins
2016-05-02 14:44
right now its just hardcoded like here: https://github.com/hyperledger/fabric/blob/master/devenv/Vagrantfile#L33
jeremyeder
2016-05-02 14:45
ok. there have to be release tags for fabric and then all the build artifacts can be sure of what they're using
ghaskins
2016-05-02 14:46
i agree, I lobbied for that but lack the access to create the tags
ghaskins
2016-05-02 14:46
so it just was lost in the shuffle
jeremyeder
2016-05-02 14:46
ok -- where's your lobbying? i would also pile on :simple_smile:
ghaskins
2016-05-02 14:46
probably just on slack
ghaskins
2016-05-02 14:47
i dont think it was dropped out of disagreement
jeremyeder
2016-05-02 14:47
gotcha, let me file something.
ghaskins
2016-05-02 14:47
just wasnt a priority to be seen through to completion
ghaskins
2016-05-02 14:47
one annoying thing with github is it doesnt seem you can submit tags as a PR
ghaskins
2016-05-02 14:48
otherwise, I would have done that along with the code PRs
ghaskins
2016-05-02 14:48
IIUC it requires someone with write access to push them
jeremyeder
2016-05-02 14:49
theres one tag now
jeremyeder
2016-05-02 14:49
0.1.0
ghaskins
2016-05-02 14:49
yeah, i am not even sure what that was
ghaskins
2016-05-02 14:50
in this context, I would have done something like “baseimage-v0.0.9” to correlate to whats in dockerhub now
jeremyeder
2016-05-02 14:51
nod
jeremyeder
2016-05-02 14:51
let me just file an issue on github and see what comes back
ghaskins
2016-05-02 14:52
but anyway, the basic workflow is something like make changes to devenv/baseimage, push it to vagrant/dockerhub, update devenv/Vagrantfile and .travis.yml to reference new version, tag it in github as baseimage-$version
ghaskins
2016-05-02 14:53
any improvements welcome, with particular interest in unifying the Vagrantfile/travis version into something any subsystem may consume, and actually getting the tags created :wink:
ghaskins
2016-05-02 14:56
@cbf: IIUC there is some kind of formal CI effort being investigated now?
ghaskins
2016-05-02 14:56
I am thinking that whole thing above could be tied in there,
ghaskins
2016-05-02 14:59
@jeremyeder: i am not sure I am misunderstanding, but from your description it almost seems like dockerhub itself can rebuild the image?
jeremyeder
2016-05-02 15:00
yep!
ghaskins
2016-05-02 15:00
thats really cool, was not aware
ghaskins
2016-05-02 15:00
I was building the images locally and pushing up
jeremyeder
2016-05-02 15:01
yeah so it will watch for a new tag
jeremyeder
2016-05-02 15:01
here let me show you
ghaskins
2016-05-02 15:01
actually for a brief moment, I was using the Packer Build service in Atlas to cloud-build both vagrant and docker, but they have since made that a premium service that isnt free
jeremyeder
2016-05-02 15:10
ghaskins: ok so
jeremyeder
2016-05-02 15:10
i just merged a new pR
jeremyeder
2016-05-02 15:13
and now i hit this... https://github.com/docker/hub-feedback/issues/313 lol
cbf
2016-05-02 15:15
@ghaskins: yes, see my discussion in the # channel - let me get the link
cbf
2016-05-02 15:17
@muralisr: you might be interested in the discussion above between @ghaskins and @jeremyeder
muralisr
2016-05-02 15:18
thanks @cbf
ghaskins
2016-05-02 15:38
@jeremyeder: IIUC you were trying to show me an example of your build-trigger but hit a bug?
jeremyeder
2016-05-02 15:49
ghaskins: yeah, i moved the github repo to a different github org
jeremyeder
2016-05-02 15:49
dockerhub does not allow you to change the source repo without creating a new automated build
ghaskins
2016-05-02 15:49
ah
ghaskins
2016-05-02 15:50
i assume you are exploiting a webhook? https://docs.docker.com/docker-hub/webhooks/
ghaskins
2016-05-02 15:52
thats cool, didn’t know we could do that
jeremyeder
2016-05-02 16:01
ghaskins: can yuo see this https://hub.docker.com/r/jeremyeder/c7perf2/builds/
jeremyeder
2016-05-02 16:01
i just created a new automated build from the new org, and it built the image. then i pushed a small change to the dockerfile, and dockerhub saw that and is rebuilding the container now.
ghaskins
2016-05-02 16:02
yep, very cool
ghaskins
2016-05-02 16:03
so, if you could figure out a way to have vagrantfile/travis consume their version from something like git-revparse and have the builds triggered by the git-push, that would be +100 from my perspective
ghaskins
2016-05-02 16:04
i assume that the dockerhub build might be $arch opinionated/limited however, so we would still need a strategy for that
joseph
2016-05-02 16:04
Hi
jeremyeder
2016-05-02 16:04
hm
ghaskins
2016-05-02 16:05
@jeremyeder: actually, even just having a file checked in like ./version -> “0.0.9” would be a huge improvement if the revparse was too difficult to stablize
jeremyeder
2016-05-02 16:06
@ghaskins: i think we need to hear from binh q nguyen
jeremyeder
2016-05-02 16:06
he looks to be committing those type of things to git.
ghaskins
2016-05-02 16:06
of course, i dont have commit privs myself anyway :wink:
jeremyeder
2016-05-02 16:06
@binhn: ping :simple_smile:

FYI, we are working on a fix for the travis failure related to the unit test in platforms/car
cbf
2016-05-02 21:20
that’s one that is affecting me
ghaskins
2016-05-02 21:20
it seems that the PR that introduced the unit-test failure was masked by a travis-infrastructure bug that gave a false positive
cbf
2016-05-02 21:20
thanks for letting me know it’s not me;-)
ghaskins
2016-05-02 21:20
nope, testing a fix now
ghaskins
2016-05-02 21:21
i think the travis failure is a red-herring, its because travis is missing a dep…the unit test passes otherwise which is how it got past
ghaskins
2016-05-02 21:21
but sorry for the noise

have not seen this error before ... what line in .feature file was it trying to execute ?
tuand
2016-05-02 22:11
nvm , i see it `../peer/peer stop`
tuand
2016-05-02 22:12
looks like it can't find the peer executable but should have run into the same thing on start up ?
tuand
2016-05-02 22:16
possible ? although we should've have seen the same error when the peer is started ... maybe something in the behave python code or the docker-compose files

ghaskins

let me try
ghaskins
2016-05-02 22:20
that was weird, now its working
ghaskins
2016-05-02 22:21
@sheehan: as far as I know, the peer wasnt running earlier either
ghaskins

@sheehan: so far PR #1329 looks like a suitable stop-gap to stop the travis failures
sheehan
2016-05-02 23:46
thanks, will take a look shortly after I’m done with the current PR I’m looking at
ghaskins
2016-05-02 23:46
sure, note that any PRs based after PR1320 and before whenever you accept 1329 will likely need to rebase if you want to see travis pass before mergibng
ghaskins
2016-05-02 23:47
of course, hand testing them may be sufficient too if you are already running those
ghaskins

is it expected result or a bug?
gengjh
2016-05-03 06:30
I think it works as design, since we support multiple transaction certification
gengjh
2016-05-03 06:31
Issues transaction certificates (TCerts) to ECert owners. An infinite number of TCerts can be derived from each ECert. TCerts are used by network participants to send transactions. Depending on the level of security requirements, network participants may choose to use a new TCert for every transaction.

@ghaskins I am try deploy Hyperledger chaincode on PPC64LE, it seem it depend on openblockchain/baseimage , where can pull this image(ppcle)? I tried use ppc64le/golang as the base image, I got the following error message and can’t deploy the chaincode:

ghaskins
2016-05-03 11:22
@aaren: support for non x86 is still WIP
ghaskins
2016-05-03 11:22
what you can do is try to build the base image locally, this is facilitated in the ./devenv/baseimage directory
ghaskins
2016-05-03 11:22
i think you will need to install packer+jq and then do “make docker"
ghaskins
2016-05-03 11:23
that will produce the baseimage installed in your local environment
ghaskins
2016-05-03 11:25
im not sure this has been tried on ppcle yet so you are in unchartered waters, though there are people looking at getting z/p added first-class in addition to x so its only a matter of time
novusopt
2016-05-03 11:49
Hi, where can i find the openblockchain/baseimage Dockerfile for the execution of chaincodes?
novusopt
2016-05-03 11:54
@ghaskins: i did what you explained on my local machine (ubuntu) but i get still the same error (see aaren's error)
ghaskins
2016-05-03 12:20
@novusopt: I suspect what you are seeing is the docker image is a 2 phased design
ghaskins
2016-05-03 12:21
we commit a strictly versioned image to dockerhub (e.g. “0.0.9”) as the first phase, and then run a provisioner script as the second phase which ingests the versioned image locally and tags it with :latest
ghaskins
2016-05-03 12:22
my guess is, you ran the “cd ./devenv/baseimage; make docker” part of the workflow (which generates the first phase artifact for dockerhub) but still need to run phase 2
ghaskins
2016-05-03 12:23
if so, the answer is that the system runs "./scripts/provision/docker.sh 0.0.9” during provisioning (such as vagrant up, travis runs, etc) that you would nee to emulate
ghaskins
2016-05-03 12:23
does this sound like your situtation?
simon
2016-05-03 12:25
i still think this is too complicated
simon
2016-05-03 12:25
i want a single command to do everything - build and test source, build images, everything
ghaskins
2016-05-03 12:30
you have it: vagrant up :wink:
ghaskins
2016-05-03 12:31
just the world isnt that simple
ghaskins
2016-05-03 12:32
part of the problem is we are using a lot of bleeding edge tech (e.g. proto3) so normal dependency mechanisms fall apart
ghaskins
2016-05-03 12:33
if it werent for that, we could probably just JIT things with apt-get and get closer to what you are asking for
ghaskins
2016-05-03 12:34
but until then, we are stuck with the need to custom build things from source and/or host the artifacts of those builds ourselves
ghaskins
2016-05-03 12:34
both have their own challenges
novusopt
2016-05-03 12:58
@ghaskins: there is no Dockerfile for the chaincode docker environment?
simon
2016-05-03 12:58
no, it is hidden in core.yml
ghaskins
2016-05-03 13:07
There are multiple dockerfiles defined in yaml
ghaskins
2016-05-03 13:08
The one you are asking about is in core.yaml at chaincode.golang iirc
ghaskins
2016-05-03 13:21
Note that almost all of them dynamically augment what's in yaml at runtime
ghaskins
2016-05-03 13:21
Via the docker api
novusopt
2016-05-03 14:06
@ghaskins: thanks! it is working
ghaskins
2016-05-03 14:07
Nice
novusopt
2016-05-03 14:13
i think we should simplify it, or provide a manual which describes how to install the fabric on the local machine
ghaskins
2016-05-03 14:21
yeah, it needs refinement
ghaskins
2016-05-03 14:21
I have an idea I want to try
novusopt
2016-05-03 14:25
@ghaskins: great
ghaskins
2016-05-03 14:26
out of curiosity, are you building non-x86 too like @aaren ?
ghaskins
2016-05-03 14:26
or was this just non-vagrant x86
novusopt
2016-05-03 14:26
non-vagrant x86 (ubuntu 14.04)
ghaskins
2016-05-03 14:26
gotcha
ghaskins
2016-05-03 14:26
i think there are a fairly large number of people with that particular config
novusopt
2016-05-03 14:27
yes
novusopt
2016-05-03 14:27
i think a good starting point would be a simple script
ghaskins
2016-05-03 14:27
well, thats what we were trying to work towards with the ./scripts/provision area
novusopt
2016-05-03 14:28
ah cool
ghaskins
2016-05-03 14:28
so, [vagrant|travis|custom|whatever] -> ./scripts/provision/*.sh at provisioning time
ghaskins
2016-05-03 14:29
right now its just docker+custom, though I was already working on delineating between host/docker and different hosts
novusopt
2016-05-03 14:29
good idea
ghaskins
2016-05-03 14:30
as per this (currently suspended) PR: https://github.com/hyperledger/fabric/pull/1327/files
ghaskins
2016-05-03 14:31
one problem is that the imperative scripts are more conducive to clean-slate provisioning such as the environments within vagrant/travis
ghaskins
2016-05-03 14:31
it might make sense to try to migrate to something more declarative like puppet so environments like yours may be properly reconciled
ghaskins
2016-05-03 14:31
but that is TBD
novusopt
2016-05-03 14:32
i see

it could be improved, but it is pretty straight-forward

@ghaskins: hey -- openblockchain/baseimage doesnt seem to include any of the fabric bits
jeremyeder
2016-05-04 13:52
is that supposed to be provided somehow else?
arner
2016-05-04 13:58
Hi @ghaskins, this was straight from the ibmblockchain/fabric image (https://hub.docker.com/r/ibmblockchain/fabric/). It seems like a bug in the build then? Is the Dockerfile available somewhere? (@jeremyeder I think this is what you would be looking for as well)
ghaskins
2016-05-04 13:59
@jeremyeder: yes, that is intentional…baseimage is just the base that we use for various fabric functions (such as devenv, chaincode-containers, and network simulation
ghaskins
2016-05-04 13:59
I can see the merits of having a complete image, but I envision that would be something in parallel to baseimage (and probably based on it)
ghaskins
2016-05-04 14:00
@arner: ah, ok, i am not familiar with the ibmblockchain build process
ghaskins
2016-05-04 14:00
i can say that we saw an illegal instruction issue in the early days that was fixed once we compiled rocksdb with the PORTABLE flag set
ghaskins
2016-05-04 14:01
so that is my guess as to what you are seeing
jeremyeder
2016-05-04 14:01
@ghaskins: ah yes ok thanks. i believe i do want an image that includes everything (what would be actually used by users not devenv)
ghaskins
2016-05-04 14:01
@jeremyeder: yeah, def a nice to have…if you come up with a pipeline for producing it im sure others would find it useful as well
ghaskins
2016-05-04 14:02
i suspect there are people already doing this, they just arent publishing it to the upstream repos
jeremyeder
2016-05-04 14:02
mmm

@arner: this is the line in question: https://github.com/hyperledger/fabric/blob/master/devenv/baseimage/scripts/common/setup.sh#L105
ghaskins
2016-05-04 14:04
failure to build with that will allow the rocksdb build to set aggressive gcc optimizations based on the platform that happens to be running the build

I have a comprehensive question, when a chaincode calls another chaincode is this then also a transaction?
ghaskins
2016-05-04 19:08
I believe it all executes under the originating transaction
ghaskins
2016-05-04 19:09
i.e. the second chaincode would see the tcert context of the caller that hit the first chaincode
ghaskins
2016-05-04 19:09
though I would also like to see the identity of the calling chaincode represented somehow, i dont think this is in place today

if you are running with security enabled, you can only deploy a chaincode when you have registered a user (its in the doc @binhn mentions)

yes, I did
arnaud
2016-05-05 14:26
I tried to be pretty thorough in looking for places where the peer command is invoked or referred to in docs so I could fix these but given how pervasive this is I may have missed some unfortunately
arnaud
2016-05-05 14:27
the ci tests failed but for some unrelated reason I believe

2016-05-05 14:49

really weird string of errors in the last 6-8 builds
jzhang
2016-05-05 22:51
@karthik: one thing that could trip you over was that unless you have security turned on in core.yaml, you must pass in the env variable in all commands including calls to init the chaincode
jzhang
2016-05-05 22:53
that happened to me on Mac where I pass in the env var during each call instead of setting it for the command line session. The instruction didn't show you need to do that for the chaincode calls.
sheehan
2016-05-05 23:51
@ghaskins: seems unit tests were failing locally due to the license change. It seemed to be a timing issue in the chaincode test. Strange because the change was comments only. On my phone so I'm having trouble seeing what's failing in CI
sheehan
2016-05-05 23:55
I backed up to https://github.com/hyperledger/fabric/commit/10395e55bebfb8b193e4d4ac42fc346801a7bcd4 locally and the build passed
ghaskins
2016-05-06 00:06
That's weird, I was looking through the commits to see what might have caused it. I saw the license patch but nothing jumped out at me as being a likely culprit
sheehan
2016-05-06 00:12
@muralisr: maybe you could take a look if you have a chance? I think a timing in one of the chaincode tests is too short
muralisr
2016-05-06 00:13
@sheehan: why do you think that
sheehan
2016-05-06 00:13
@ghaskins: yeah, very strange. I looked through it carefully and only saw comments and white space changes
sheehan
2016-05-06 00:14
@muralisr: because it was a comment only change, but now the test is failing. Not sure what else it may be

so the later won’t fail for changes to example02 and the former will
simon
2016-05-06 11:47
this is not a trivial issue - what are the semantics of upgrading a chaincode? should all chaincodes start using the new version?
simon
2016-05-06 11:48
shouldn't they have a choice on whether they should use the new version or not?
muralisr

well, that’s the purpose of the two examples - to show the effect of hard coding ids. But changing example02 is not really an “upgrade” as something known to the system.
muralisr
2016-05-06 12:00
@sheehan: @ghaskins - will run the latest and push out a PR to fix the test case if chaincode example02 has changed. I’ll also put a comment in chaincodeexample02 to note changes to 02 will affect 04

@muralisr: this seems to indicate the Go binaries do include source. I also read they're adding a feature in 1.7 to optionally not include the source. I remember we were asking this question for system chaincode
muralisr
2016-05-06 12:43
@sheehan: the unit tests run on the local file system and the peer image we create has the file system. It is only when you use the peer exe without the files in GOPATH that we will have a problem… right ?

How do i check the signature of a transaction within a chaincode. There is an example asset management which checks the signature, but they are using the metadata that means it is done manually

Hi @sheehan , @muralisr : so was that error determined? I'm running into a similar error when calling one cc from another (ie client(dev cmndline) -> cc1 -> cc2). If there is no error in cc2, it works fine, but if cc2 returns an Error (whether in an invoke or query), I get this type of error (ie Chaincode handler FSM cannot handle message) and cc1 gets killed even before it can print the response from cc2.
novusopt
2016-05-06 13:07
@simon: @adc or can i skip this in the chaincode because the validator checks already the signature?
simon
2016-05-06 13:07
the validator doesn't know what you want to check the signature against

2016-05-06 13:08
(this was on sha 53c67ac btw)
novusopt
2016-05-06 13:09
@simon: i think the validator checks the signature of every transaction, "does the user have the correct private key to the corresponding public key"....
simon
2016-05-06 13:09
well, but for asset management, you don't know who owns the asset

I am experiencing a suspicious behaviour when using the default dev setup (noobs consensus). If I boot up three nodes, vp0, vp1, vp2 and init some contracts to vp0, then all three nodes sync them and I can query / invoke contracts from any of them. However, if I turn off one of the node and boot it up again, even if it picks up the network, it does not get the contracts in the blockchain - I can't query the reborn. Is this the expected behaviour? I would rather have the new one syncing the contracts and after a while, being able to query it. Happy to dump here any trace if needed.

[Question] When and Who write to DB (rocksDB) ?
--
By looking at fabric (not extensively, but roughly), it looks like to me what each "peer" process keeps world state in the memory, and when the consensus is made against transaction, it records to it's "world state" (in memory). And it is written to RocksDB at some point (this is a question). I could not understand the condition when and who writes into the DB. As for writing the DB, looks like each "peer" process writes to rocksDB based on current world state, and world state is synced frequently within a network. If wring to DB is correct, question is a condition of writing to the DB. This came to my mind what will happen "when 1 peer has lost the connection due to the power outage or data center maintenance for 1 day, and can it recover the world state?" The last test might be able to done in local env.
ibmamnt
2016-05-09 06:07
[Question 2] When the world state syncronized ?
--
I have setup 4 peers with "docker-compose-4.yml" configuratio found in bddtest folder. After running 4 peers, I run several transaction, and then stopped one of it "vp3". And I have run several transactions. After it, I restarted "vp3". I see this inconsistency.
```$ curl -s http://172.17.0.3:5000/chain/ | jq '.height'
11
$ curl -s http://172.17.0.4:5000/chain/ | jq '.height'

$ curl -s http://172.17.0.3:5000/chain/blocks/10 | jq '.transactions[].uuid'

ibmamnt
2016-05-09 06:07
vp3 (http://172.17.0.4 in my env) is reporting block height '8' rather than '11'. And seems it does not change.

i hope @garisingh can give some guidance on this
simon
2016-05-11 09:24
I think transactions that fail (error return) should not be part of the block
garisingh
2016-05-11 09:25
@sheehan should be able to provide more details, but basically when you call "Put State" from within chaincode, the actual persisted state (i.e. what is stored in rocksdb) is not actually being updated yet. After a successful invocation of your chaincode function (meaning no unhandled exceptions or no exception created), what you end up with is basically an in-memory collection of the proposed state changes. Depending on the consensus algorithm and config parameters, at some point Commit is called by the system and at that time we actually attempt to write the changes to the database. If one of those Put calls results in an error, then things get rolled back (and as a matter of fact, if this was in a block of transactions, at this point I believe the entire block fails). But @sheehan can correct me where I am wrong
joseph
2016-05-11 09:25
@simon Actually, at step 3 I made it return an error based on a condition.
simon
2016-05-11 09:25
currently there is a single database transaction encompassing multiple chaincode transactions, but we may have to be able to roll back individual chaincode transactions
simon
2016-05-11 09:26
joseph: ah, so after the last putstate you return an error?
simon
2016-05-11 09:26
joseph: or do you mean you invoke 3 times?
garisingh
2016-05-11 09:26
@joseph - if your chaincode throws an exception, no state changes will occur, the tx is not processed and I don't believe the tx is in any block
joseph
2016-05-11 09:26
return an error after step 3.
garisingh
2016-05-11 09:27
each invoke on chaincode results in an atomic set of state changes - it's all or none. and if being processed as part of a batch, it is currently all or none for the batch
simon
2016-05-11 09:27
garisingh: i don't think so?
simon
2016-05-11 09:27
is that really the case?
garisingh
2016-05-11 09:28
I could be totally wrong :wink:
simon
2016-05-11 09:28
i think the errors are just collected
garisingh
2016-05-11 09:28
@sheehan best to answer - but I am pretty sure that is how it mostly works
simon
2016-05-11 09:28
but it doesn't matter much how it currently works - we should figure out how we want it to work
simon
2016-05-11 09:28
what are the correct semantics?
simon
2016-05-11 09:29
i think chaincode being able to abort the whole block is dangerous
garisingh
2016-05-11 09:30
so - the result of a chaincode invocation is going to be a set of one or more state changes. I think we can agree that those should be all or nothing. Within chaincode, you can handle any errors you want, but if you return success, I think all state changes made should be considered an atomic set of operations
simon
2016-05-11 09:31
yes
garisingh
2016-05-11 09:32
on the batch thing, I agree that one tx should not roll back an entire block, although this can be quite tricky depending on the transactions. this is probably why we do need to think about some type of MVCC approach
simon
2016-05-11 09:32
right
simon
2016-05-11 09:32
that will address a lot of issues
simon
2016-05-11 09:32
we really need to think of this as a database, not of some undefined something system
garisingh
2016-05-11 09:33
agreed
garisingh
2016-05-11 09:33
now we can probably be intelligent about things as well given that state is associated with chaincode - so if there was a batch of tx and they all invoked different chaincode / functions / state, perhaps we can optimize as well

But I am pretty sure that I am close to being correct in how things work in the code today as implemented
joseph
2016-05-11 09:34
For confirmation, in case of returning an error within my chaincode, no states were saved at step 1, 2 and 3?
garisingh
2016-05-11 09:34
correct
simon
2016-05-11 09:35
it should be so
simon
2016-05-11 09:35
i'll have a look
joseph
2016-05-11 09:35
Nice. Thanks you, guys.
simon
2016-05-11 09:41
garisingh: i think you're right. the code rolls back the current tx state
simon
2016-05-11 09:41
but then, why do we record the transaction and the error in the block?
garisingh
2016-05-11 09:45
@simon - interesting - I recall at one point that not being the case although I could be wrong there as well. I guess if we think about it, the transaction was technically invoked and perhaps it is valuable to know that your transaction resulted in an error. And of course given that tx processing is async from the invoker's perspective, the only place to store the "result" (even if an error) is the ledger.
garisingh
2016-05-11 09:45
but confusing all around
simon
2016-05-11 09:45
it seems simple
simon
2016-05-11 09:47
but that's some DoS potential - I could invoke one chaincode over and over. say I don't have the authorization or the balance to perform that transaction; that would mean that I could spam the blockchain
simon
2016-05-11 09:47
and this can't be cleared easily later
simon
2016-05-11 09:49
garisingh: there are certainly situations where a transaction is considered invalid and never makes it in a block. because we have to handle those as well, we could use the same mechanism to notify transaction errors
garisingh
2016-05-11 09:50
agreed
garisingh
2016-05-11 09:52
perhaps it exists, but it would probably be helpful to have a flow diagram of the state machine replication
garisingh
2016-05-11 09:54
e.g. more details on ```submit / invoke transaction --> consensus --> ordered list of transactions --> execute chaincode --> collect state changes --> process state changes ... ```
garisingh
2016-05-11 09:55
IMHO, we actually have 2 state machines - one to execute chaincode (outputting proposed state changes) and another to actually process the state changes
simon
2016-05-11 09:56
you mean a message flow diagram?
simon
2016-05-11 09:57
i can try to create that
garisingh
2016-05-11 09:59
basically the flow of a message from submission until it reaches the ledger
garisingh
2016-05-11 09:59
and everything that happens in between :wink:

@simon - I spoke with @jyellick and @kostas about doing something similar for consensus (including checkpointing). Perhaps we can combine these together. I think this would be very helpful for everyone in the community as it is not clear from the protocol spec alone how everything flows together. Let me know how I can help as well

added a sample yesterday that may be useful for testing https://github.com/hyperledger/fabric/blob/master/examples/chaincode/go/passthru/passthru.go
muralisr
2016-05-11 13:56
it just passes Invoke / Query arguements to another chaincode… the called chaincode ID is sent via the “Function” parameter
suma
2016-05-11 13:59
@muralisr: this is very interesting. I have chaincodes calling chaincodes. Does this approach have performance advantages?
muralisr
2016-05-11 14:01
@suma likely not. Main goal was to write cc-to-cc tests quickly
suma
2016-05-11 14:01
ok. got u. neat, thoguh. i’ll try it. i think it will be useful for me nevertheless
sheehan
2016-05-11 14:11
@garisingh: haven’t read the entire conversation, but you’re correct about state changes being held in memory until the block is committed. At that point it’s written to the DB. We do have the ability to roll back either individual transactions or the entire block. It’s up to the consensus mechanism if they use this functionality
muralisr
2016-05-11 14:26
^^ just add to this from a chaincode point of view…. transaction execution can (1) return with a fabric error (2) return with a chaincode error and (3) return success.
muralisr
2016-05-11 14:27
(1) and (2) will cause the state of the transaction to be rolled back. The transaction itself will be entered in the block for non-sieve consensus (sieve may have other subtleties from a block creation point of view… @simon ?)

I am running the docker-based setup and my peer is running on ip 172.17.0.2:30303. I am not able to use the REST api from my windows (Host) machine on that peer. How should I do this?
mcrafols
2016-05-12 07:40
you are running it inside vagrant right¿
ibmamnt
2016-05-12 08:07
@nits7sid: If you want to run apis from outside of Docker host machine, probably easiest way to setup port forward something like:
```docker run --name=vp0 \
--restart=unless-stopped \
-it \
-p 5000:5000 \
-p 30303:30303 \
-e CORE_PEER_ID=vp0 \
-e CORE_VM_ENDPOINT=http://172.17.0.1:4243 \
-e CORE_PEER_ADDRESSAUTODETECT=true \
hyperledger-peer peer peer```
ibmamnt
2016-05-12 08:08
Then you should be able to access from remote machine using port:5000 (restAPI port).

Question regarding `peer chaincode` comamands:
I assume `-p` and `-l` are only relevant to `chaincode deploy`, and `-n` is only relevant to `chaincode query/invoke`. Is that correct?
sheehan
2016-05-13 15:27
yes, I believe that’s the case
muralisr
2016-05-13 15:46
@dmurik… the one exception is if you are running in —peer-chaincodedev mode
muralisr
2016-05-13 15:47
then you do “./peer chaincode deploy -n “the_name_I_gave_to_chaincode"
muralisr
2016-05-13 15:47
basically you are saying “already deployed…just use this name to send init"
dmurik
2016-05-13 17:26
@muralisr: Thanks for that. I noticed that this is actually mentioned in `docs/API/CoreAPI.md` but under a section called "Devops [DEPRECATED]". I assume it would be a good idea to make this documented somewhere else too...

Hi all, just wondering what encryption algorithm the Fabric uses?
garisingh
2016-05-16 21:22
@paulx: for transactions, we use AES256 in CFB mode
garisingh
2016-05-16 21:22
the symmetric encryption key is derived using ECIES
paulx

Hi all, I'm new to Hyperledger and I'm trying to follow this guide to set up a network for development: https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/devnet-setup.md
I can start up the first and the second peer, but when I try to deploy the chaincode to the network, I never see the message ```"Received build request for chaincode spec"``` on the output screen of any of the peers.
Instead, I can only see ```16:33:40.960 [container] WriteGopathSrc -> INFO 021 rootDirectory = /opt/gopath/src ``` in the first peer.
Any help would be greatly appreciated, thank you!
dmurik

I think the hyperledger/fabric and the fabric-api don't work together at this time. I believe.
nickmelis
2016-05-18 14:50
ah….and who does the fabric-api work with?
guglielmo_n
2016-05-18 14:51
All, @dmurik , @muralisr,
This is the current situation, I can find the chaincodeID in the peer logs, for example:
```08:04:58.423 [chaincode] beforeRegisterEvent -> DEBU 71b Got REGISTER for chaincodeID = name:"1edd7021ab71b766f4928a9ef91182c018dffb86fef7a4b5a5516ac590a87957e21a62d939df817f5105f524abddcddfc7b1a60d780f02d8235bd7af9db81b66" , sending back REGISTERED```
but the ```peer chaincode deploy ...``` command does not print the ID, which makes it pretty unusable ATM from a client's standpoint.
nickmelis
2016-05-18 14:51
and where does it come from?
grapebaba
2016-05-18 14:52
you can ask @ghaskins
ghaskins
2016-05-18 14:54
the id is a composite hash of several parameters, including a hash of the chaincode itself, the ctor parameters, etc….as far as retrieving it from the command, I am not sure as I use the REST interface directly, typically
ghaskins
2016-05-18 14:54
(it is returned in the deploy response, but not sure how to get the peer-chaincode subcommand to display it
guglielmo_n
2016-05-18 14:57
According to https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/devnet-setup.md it should (or used to) print it!
guglielmo_n
2016-05-18 15:01
@ghaskins: yeah it seems to be better to use the REST APIs in this particular case, thank you.
ghaskins
2016-05-18 15:02
I thought it did too, but I havent used it in a while
nickmelis
2016-05-18 15:03
@grapebaba, @ghaskins, is it only possible to interact with an HyperLedger node via REST APIs at the moment then?
grapebaba
2016-05-18 15:08
i remember ghaskins told me fabric expose both rest and grpc service
grapebaba
2016-05-18 15:10
fabric-api seems a SDK to support grpc

I am writing sth with the fabric. but Rest API is not enough. I should make it work with the fabric over grpc.

ibmamnt
2016-05-19 04:36
@yingfeng, though I have not tried, I may want to export the three images (hyperledger/fabric-baseimage, hyperledger-peer and membersvc) from your Vagrant image, and import to non vagrant envrironment.

quick question on the example at https://github.com/hyperledger/fabric/blob/master/examples/chaincode/go/chaincode_example01/chaincode_example01.go
nickmelis
2016-05-20 10:28
why does the Query function does nothing?
garisingh
2016-05-20 10:47
@nickmelis: looks like it is basically a stateless chaincode example as no state is ever stored anywhere which would make Query a no-op
garisingh
2016-05-20 10:47
example02 is the one most commonly used to start with to look at Put / Get state
nickmelis
2016-05-20 10:47
right, in fact it looks like the 02 is the fully functional one
garisingh
2016-05-20 10:48
yep
simon
2016-05-20 11:06
that's how it should be
nickmelis
2016-05-20 11:08
I’m playing with example02, right after deploying the chaincode with two entities (Bob and Tom) I try to query for both, and I get an error saying {'Error':'Nil amount for Bob'}
nickmelis
2016-05-20 11:08
how’s it possible?
simon
2016-05-20 11:11
the deploy takes some time to execute
nickmelis
2016-05-20 11:12
even after some time, I get the same result
nickmelis
2016-05-20 11:12
how long does it take?
simon
2016-05-20 11:13
it needs to compile the chaincode - possibly even download a docker container first
simon
2016-05-20 11:13
on my machine it sometimes takes 40 sec
nickmelis
2016-05-20 11:14
when I get back the chaincode name, does it mean the code has been compiled?
simon
2016-05-20 11:14
no
simon
2016-05-20 11:14
it means that the request has been submitted
nickmelis
2016-05-20 11:15
even after a while, it still throws the same error
nickmelis

unless you have some additional containers running, the container may still be being assembled
nickmelis
2016-05-20 11:18
@karthik: yes exactly, Bob 100 and Tom 200
nickmelis
2016-05-20 11:19
same as the example at https://github.com/hyperledger/fabric/blob/master/docs/API/CoreAPI.md#chaincode

I understand that we deploy chaincode ony once. In practice, the chaincode can be updated in time. So how to redeploy in an effective way?
muralisr
2016-05-21 15:26
@joseph @nickmelis currently, there is not satisfactory solution to “redeploy” and in general maintenance. The best you can do is “deploy” a variation. As @ghaskins pointed out there is planning in progress to upgrade and terminate no specific timeline at the moment unfortunately…but should happen after due process in the community
joseph
2016-05-21 15:29
I see.
joseph
2016-05-21 15:31
by the way, a state of a chaincode that stored in the world state is cloned to all validators or it is kept locally ?
ghaskins
2016-05-21 15:41
Ignoring confidentiality constraints, cloned

@joseph - which certificate are you looking for?
garisingh
2016-05-22 09:20
@joseph - to answer your state question above, in the current implementation of the fabric, chaincode runs on all validating nodes and therefore the state produced by any given chaincode is available on all validating nodes as well. technically the state itself is not "cloned" but rather what happens is that the functions you invoke against chaincode are actually executed against chaincode on each validating node (the one exception is when a node falls behind / reconnects to the network, but that is a different discussion)

joseph
2016-05-22 09:23
@garisingh: thank your for your answer for the question above.
garisingh
2016-05-22 09:27
@joseph - the certificate of the client which called a chaincode function is available via `stub.GetCallerCertificate()`
garisingh
2016-05-22 09:31
the `stub.GetCallerMetaData()` function will only return info if you actually included metadata in the deploy and / or invoke transaction
joseph
2016-05-22 09:33
stub.getCallerCertificate() is returning a certificate.
joseph
2016-05-22 09:33
@garisingh: Thanks
joseph
2016-05-22 09:34
For confirmation, is that a deployer certificate?
garisingh
2016-05-22 09:34
not sure what you mean by "deployer" certificate?
joseph
2016-05-22 09:36
I looked some chaincode examples.
joseph
2016-05-22 09:37
They said we should get a deployer certificate by calling stub.GetCallerMetata() and so on.
garisingh
2016-05-22 09:41
which examples? for stub.GetCallerMetata() to return anything, you actually have to send metadata with the transaction (either a deploy or invoke transaction). You can see this here: https://github.com/hyperledger/fabric/blob/master/examples/chaincode/go/asset_management/app/app_internal.go#L129

Hi, I’ve stood up a cluster of 4 validating peers (with pbft consensus plugin and security enabled) as well as a member services node and everything seems to be functioning properly. I’ve deployed, invoked, and queried the example chaincode [https://github.com/hyperledger/fabric/tree/master/examples/chaincode/chaintool/example02] using the REST API and have moved onto the asset management chaincode [https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management]. However, I can’t seem to figure out how to interact with this chaincode via the REST API. Are there any documented REST calls for it / has anyone successfully done this themselves? Many thanks! cc: @guglielmo_n @sjcorbett

It seems the payload has more information than transaction. For example, if I query like /transactions/{uuid}, I get like:

chaincode rest api always meets time out when i setup a simple develop enviornment:
1. docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp1 -e CORE_PEER_ADDRESSAUTODETECT=true -e CORE_PEER_DISCOVERY_ROOTNODE=172.17.0.2:30303 hyperledger-peer peer node start --peer-chaincodedev
2. CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=172.17.0.2:30303 ./chaincode_example02
3. curl -H "Content-Type: application/json" --data @deploy.json http://172.17.0.2:5000/chaincode
where deploy.json is:
{
"jsonrpc": "2.0",

},
"ctorMsg": {
"function":"init",

4. the calling of curl meets time out frequently, sometimes it's successful. why does it happen?

I've got the reason: when development enviornment is used, don't use docker to start peer node

@ghaskins: you told me to put it in the $GOPATH/src and set the path from there

I have not been succesful in setting the path to the chaincode

@mcrafols: it seems that at some point (im guessing with go1.6), fully qualified paths seem to work
ghaskins
2016-05-24 15:39
it used to be true that type=GOLANG required $GOPATH/src relative paths, but a colleague of mine pointed out recently that this doesn’t appear to be true any more
ghaskins
2016-05-24 15:40
to be clear, it must be an FQP w.r.t. the peer that will handle the deploy()
ghaskins
2016-05-24 15:40
not the client (unless you are running the client on the same machine, in which case they are equivalent)

2016-05-24 15:41
yes, we know this is annoying, yes, it is being worked on, but for now, thats how it works...
nickmelis
2016-05-24 15:42
@mcrafols: the only way I’ve found to deploy and test a chaincode without using a GitHub repo is by following this guide: https://github.com/hyperledger/fabric/blob/master/docs/API/SandboxSetup.md
nickmelis
2016-05-24 15:42
It’s some sort of development sandbox, so I don’t know if this is what you’re looking for
mcrafols
2016-05-24 15:43
@nickmelis: yes, I have developed the chaincode on it, but wan't to do the next step and deploy it over a VP network
nickmelis
2016-05-24 15:43
yeah I think we’re all waiting for it :slightly_smiling_face:
ghaskins
2016-05-24 15:43
@mcrafols: your only choices right now are to have the chaincode available via URL, or installed in a FQP on the peer that you plan to send the deploy() to
ghaskins
2016-05-24 15:44
you only need to have it accessible on the peer that handles the deploy() directly, as the first peer will package and distribute the code to the others after that
nickmelis
2016-05-24 15:44
@ghaskins: what’s FQP?
ghaskins
2016-05-24 15:44
fully qualified path
ghaskins
2016-05-24 15:45
i.e. root relative
nickmelis
2016-05-24 15:45
right, so to have it in $GOROOT/src?
ghaskins
2016-05-24 15:46
if its not fqp (meaning, does not have a root slash, e.g. “my/awesome/chaincode”, then I think it will prepend $GOPATH/src to that
ghaskins
2016-05-24 15:46
if it has a leading slash, then its an FQP taken verbatim
ghaskins
2016-05-24 15:46
e.g. /home/nickmelis/my/awesome/chaincode
mcrafols
2016-05-24 15:47
would this work when the VP runs in the docker image?
ghaskins
2016-05-24 15:47
if you put your chaincode in the docker image with it :wink:
nickmelis
2016-05-24 15:47
right, so you’re saying I can put my chaincode into /home/nickmelis/my/awesome/chaincode on the VP and then call deploy() via REST passing the fully qualified path?
ghaskins
2016-05-24 15:47
bottom line: _not_ using URL means it has to be in the local filesystem of the peer that will accept the request
ghaskins
2016-05-24 15:48
@nickmelis: yes
ghaskins
2016-05-24 15:48
@mcrafols: if you are using a docker container for your peer, the local fs for the peer is the docker container
nickmelis
2016-05-24 15:48
@ghaskins: cool, thanks! that was useful
mcrafols
2016-05-24 15:49
@ghaskins: $GOPATH/src/github.com/hyperledger/fabric/core/container ?
ghaskins
2016-05-24 15:49
@mcrafols: how are you launching the peer?
mcrafols
2016-05-24 15:50
docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp0 -...
mcrafols
2016-05-24 15:50
because as far as I know launching it outside the image is challenging
mcrafols
2016-05-24 15:50
at least
ghaskins
2016-05-24 15:50
i assume at the end of that you are referencing hyperledger-peer
mcrafols
2016-05-24 15:50
hyperledger-peer peer node start
mcrafols
2016-05-24 15:51
yes sorry
ghaskins
2016-05-24 15:51
right, ok, so if you run “docker images” you will see “hyperledger-peer” is a container on your system
mcrafols
2016-05-24 15:51
yes
ghaskins
2016-05-24 15:51
that image was created (directly or indirectly) via “make peer-image” at some point earlier
nickmelis
2016-05-24 15:51
ok I’ve just tried with the FQP and it works…great news :slightly_smiling_face:
ghaskins
2016-05-24 15:52
@nickmelis: awesome!
ghaskins
2016-05-24 15:52
@mcrafols: so you have a few different choices
mcrafols
2016-05-24 15:52
@nickmelis: are you running you VP without docker?
nickmelis
2016-05-24 15:52
@mcrafols: yes I am…single peer
ghaskins
2016-05-24 15:52
#1 inject what you want into either hyperledger-peer (or create a derivative image from hyperledger-peer)
ghaskins
2016-05-24 15:53
#2 keep using hyperledger-peer but use a volume mount to make your chaincode visible to the container
ghaskins
2016-05-24 15:53
#3 stop using docker and run the peer directly
ghaskins
2016-05-24 15:53
it sounds like @nickmelis is using option 3
nickmelis
2016-05-24 15:54
I am, although I am only running a single node
nickmelis
2016-05-24 15:54
not a proper network...
ghaskins
2016-05-24 15:54
yeah, for simple things that works fine
nickmelis
2016-05-24 15:54
yeah exactly
ghaskins
2016-05-24 15:54
FWIW, I very rarely do anything but exactly this
ghaskins
2016-05-24 15:54
I tend to be testing chaincode function and dont care about consensus
nickmelis
2016-05-24 15:55
it would be really useful to have visibility over the fabric roadmap and see what’s being planned for the next few months
mcrafols
2016-05-24 15:55
regarding #3 many people have had problems deploying it outside docker, right?
ghaskins
2016-05-24 15:55
@mcrafols, not sure why…the host environment (at least if you are using vagrant) is virtually identical to the docker environment
ghaskins
2016-05-24 15:56
so, unless you need multiple nodes or isolation, it should be more or less the same
ghaskins
2016-05-24 15:56
you are limited that you can only run 1 instance without rigging all the paths/ports (like /var/hyperledger and port 30303)
ghaskins
2016-05-24 15:56
but it should be operationally similar
ghaskins
2016-05-24 15:57
@nickmelis: I think we all want that :wink:
mcrafols
2016-05-24 15:57
ok, but I am trying with multiple VP because I have two clients and they can't point to the same VP
nickmelis
2016-05-24 15:57
@ghaskins: sorry guys, I don’t want to make pressure on you :stuck_out_tongue:
ghaskins
2016-05-24 15:58
@mcrafols: ok, then you need docker
ghaskins
2016-05-24 15:58
so, you can attack from option 1 or 2, 2 is probably the better choice IMO
ghaskins
2016-05-24 15:58
hold on, let me look up the option you want
ghaskins
2016-05-24 16:01
ghaskins
2016-05-24 16:02
@ghaskins uploaded a file: https://hyperledgerproject.slack.com/files/ghaskins/F1BCHFPC2/-.sh and commented: for instance
ghaskins
2016-05-24 16:03
this maps /local-dev on the host to /local-dev in the container
ghaskins
2016-05-24 16:04
change the paths to taste, though this is probably a good configuration if you are using vagrant+LOCALDEVDIR option
ghaskins
2016-05-24 16:04
once that is done, you should be able to use an FQP like /local-dev/path/to/my/awesome/chaincode and the peer will be able to see it
mcrafols
2016-05-24 16:05
oh great (awesome indeed)! let me try it
nickmelis
2016-05-24 16:10
cos every node need to have access to the chaincode, right? and with a shared folder you just drop the chaincode in there, am I right?
mcrafols
2016-05-24 16:10
not every node
mcrafols
2016-05-24 16:10
just the one where you are doing the deploy
nickmelis
2016-05-24 16:10
then why do you need the other nodes to have access to the chaincode?
mcrafols
2016-05-24 16:11
when you do this set up of a network: https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/devnet-setup.md
mcrafols
2016-05-24 16:11
that allows to build several peers
mcrafols
2016-05-24 16:11
you run them in docker images (it's like having a VM for every peer)
mcrafols
2016-05-24 16:12
so this peers run in a VM that cannot access the host filesystem
nickmelis
2016-05-24 16:13
ok you’re saying you run ALL the nodes in docker?
nickmelis
2016-05-24 16:13
in this case you just need to share a folder from the host to ONE of your docker images, am I right?
mcrafols
2016-05-24 16:13
yes every node is a docker image
mcrafols
2016-05-24 16:13
exactly
nickmelis
2016-05-24 16:13
ok got it!
nickmelis
2016-05-24 16:14
if you deploy on one node, does it then get propagated to the other nodes automatically?
mcrafols
2016-05-24 16:14
yes via consensus
nickmelis
2016-05-24 16:14
so I can deploy on node 1 and invoke on node 2?
mcrafols
2016-05-24 16:14
that's the nice thing of distributed systems
mcrafols
2016-05-24 16:15
like blockchain
nickmelis
2016-05-24 16:15
yeah I know this is the case with Ethereum for example, I just thought it wasn’t ready yet
nickmelis
2016-05-24 16:15
so the only issue to solve is make the chaincode source available to ONE of the validating peers, right?
mcrafols
2016-05-24 16:16
yes
nickmelis
2016-05-24 16:16
ok I got it now!
ghaskins
2016-05-24 16:18
sorry, was in the other channel, but @mcrafols is right
ghaskins
2016-05-24 16:18
only the peer that receives the actual deploy needs to access the URL/filesystem
ghaskins
2016-05-24 16:18
all other nodes get a copy via the consensus network
mcrafols
2016-05-24 16:19
I am running this command:
vagrant@hyperledger-devenv:v0.0.9-66ca505:/local-dev$ docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT=true -v /local-dev:/local-dev hyperledger-peer peer node start
mcrafols
2016-05-24 16:20
@ghaskins: from what you suggested, where /bin/bash would go?
ghaskins
2016-05-24 16:38
@mcrafols: sorry, that was just for my example
ghaskins
2016-05-24 16:38
you dont need/want it
ghaskins
2016-05-24 16:39
should have been your same command + “-v /local-dev:/local-dev”, thats it
ghaskins
2016-05-24 16:39
looks like you have it right
mcrafols
2016-05-24 16:40
so I have the chaincode right to the vagrant /local-dev/
mcrafols
2016-05-24 16:40
and then this
mcrafols
2016-05-24 16:40
vagrant@hyperledger-devenv:v0.0.9-66ca505:/opt/gopath/src/github.com/hyperledge
r/fabric/peer$ CORE_PEER_ADDRESS=172.17.0.2:30303 ./peer chaincode deploy -p /l
ocal-dev -c '{"Function":"init", "Args": []}'
mcrafols
2016-05-24 16:41
@mcrafols uploaded a file: https://hyperledgerproject.slack.com/files/mcrafols/F1BCK8N4X/Untitled.txt
mcrafols
2016-05-24 16:42
keeps saying path does not exist
ghaskins
2016-05-24 16:42
if your chaincode in the same dir you volume mounted, I would have epxected that to work
ghaskins
2016-05-24 16:42
you can trouble shoot with bash
ghaskins
2016-05-24 16:42
at the end of your peer-launch, instead of “peer node start” put “/bin/bash
ghaskins
2016-05-24 16:43
and then cd /local-dev, does it look like you expect>
ghaskins
2016-05-24 16:43
?
mcrafols
2016-05-24 16:43
yes
mcrafols
2016-05-24 16:43
the chaincode is there
ghaskins
2016-05-24 16:45
hmm, ok, i thought FQP worked, let me try something
mcrafols
2016-05-24 16:45
well @nickmelis was succesful using the FQP
ghaskins
2016-05-24 16:46
(worst case, you could use /local-dev/src/mycode with GOPATH=/local-dev
ghaskins
2016-05-24 16:46
but yeah, and I have some colleagues here that have been using FQP too, IIUC
ghaskins
2016-05-24 16:46
the bigger challenge was getting your code into the container, we hve that now
ghaskins
2016-05-24 16:46
now just need to work out the mechanics of the specification
mcrafols
2016-05-24 16:48
wait
mcrafols
2016-05-24 16:48
when I do the /bin/bash
mcrafols
2016-05-24 16:48
it get to this path root@8988af087f27:/opt/gopath/src/github.com/hyperledger/fabric/peer#
ghaskins
2016-05-24 16:51
thats fine, thats because the hyperledger-peer has a CWD set
ghaskins
2016-05-24 16:51
do a “df”, you should see your /local-dev mounted
mcrafols
2016-05-24 16:52

mcrafols
2016-05-24 16:53
I thought that maybe it couldn't find the folder because it was looking from the .../peer path
ghaskins
2016-05-24 16:57
no, it should be fine since it was fully qualified
ghaskins
2016-05-24 16:57
to prove it, try this: docker run -it -v /local-dev:/local-dev hyperledger-peer ls /local-dev
ghaskins
2016-05-24 16:57
you should see whatever you mounted
ghaskins
2016-05-24 16:58
this is probably a stupid question: but are you sure you are directing your deploy to the right container?
mcrafols
2016-05-24 16:59
yes to the VP that I ran with -v /...
ghaskins
2016-05-24 16:59
ok
ghaskins
2016-05-24 17:00
did the ls test pan out?
mcrafols
2016-05-24 17:00
when I run your command I see the contents in the /local-dev of vagrant
ghaskins
2016-05-24 17:00
that sounds right to me
ghaskins
2016-05-24 17:00
is that not what you expected?
mcrafols
2016-05-24 17:00
it is
mcrafols
2016-05-24 17:00
and the chaincode is there
ghaskins
2016-05-24 17:00
ok
ghaskins
2016-05-24 17:01
let me ask you this: is /local-dev a chaincode package, or a single .go file?
ghaskins
2016-05-24 17:01
@nickmelis: when you launch with FQP, are you specifying the folder or a .go file ?
mcrafols
2016-05-24 17:02
a single .go file
ghaskins
2016-05-24 17:02
@mcrafols: not sure this will work, but try /local-dev/file.go
ghaskins
2016-05-24 17:02
i wonder if there is some goofiness because im sure your package isnt “local-dev"
ghaskins
2016-05-24 17:03
if the direct file doesnt work, try moving the file to its proper package folder under local-dev
mcrafols
2016-05-24 17:05
what do you mean by proper package folder?
mcrafols
2016-05-24 17:05
it does not work
mcrafols
2016-05-24 17:06
if i set the path to . then it tries to deploy something
mcrafols
2016-05-24 17:06
but then does this
ghaskins
2016-05-24 17:06
well, you know how go has packages like “foo/bar”, which would expect any files in foo/bar/*.go to have “package bar” at the top
mcrafols
2016-05-24 17:06
@mcrafols uploaded a file: https://hyperledgerproject.slack.com/files/mcrafols/F1BCHCX7E/-.txt
ghaskins
2016-05-24 17:07
thats weird, it looks like it built something
mcrafols
2016-05-24 17:07
yeah I get the same if I try the path /
mcrafols
2016-05-24 17:09
@mcrafols uploaded a file: https://hyperledgerproject.slack.com/files/mcrafols/F1BD5TRA6/-.txt
mcrafols
2016-05-24 17:09
I don't understand what's trying to deploy
mcrafols
2016-05-24 17:09
but those are the only paths that have "worked"
ghaskins
2016-05-24 17:09
at this point, probably best if @nickmelis or someone else that has used FQP could chime in
ghaskins
2016-05-24 17:09
one last thing to try:
ghaskins
2016-05-24 17:10
make a GOPATH like structure under your /local-dir and then set it
ghaskins
2016-05-24 17:10
e.g. docker run …. -e GOPATH=/local-dev ….
ghaskins
2016-05-24 17:11
then use a relative gopath name
mcrafols
2016-05-24 17:12
trying the deploy like this?
CORE_PEER_ADDRESS=172.17.0.2:30303 ./peer chaincode deploy -p $GOPATH -c '{"Function":"init", "Args": []}'
ghaskins
2016-05-24 17:12
no i mean on the vp0 launch
ghaskins
2016-05-24 17:13
say install your code in /local-dev/src/mycode
mcrafols
2016-05-24 17:13
yeah I did the launch like this
mcrafols
2016-05-24 17:13
POINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT
=true -e GOPATH=/local-dev -v /local-dev:/local-dev hyperledger-peer peer node
start
ghaskins
2016-05-24 17:13
ok, good
ghaskins
2016-05-24 17:13
now, using my example above, you would do “peer chaincode deploy -p mycode …"
mcrafols
2016-05-24 17:14
mycode being the go file?
ghaskins
2016-05-24 17:14
im not sure if it wants a package or file
ghaskins
2016-05-24 17:14
try both
mcrafols
2016-05-24 17:15
i think the package
mcrafols
2016-05-24 17:15
but i'll try both
mcrafols
2016-05-24 17:18
it seems that it deploys something
mcrafols
2016-05-24 17:18
because I made the folder eNot
mcrafols
2016-05-24 17:18
and trying the deploy it gives this error
mcrafols
2016-05-24 17:20
@mcrafols uploaded a file: https://hyperledgerproject.slack.com/files/mcrafols/F1BCY7QLF/-.txt
mcrafols
2016-05-24 17:22
it is kind of getting something, because if I deploy also specifying the file.go
mcrafols
2016-05-24 17:22
it says
mcrafols
2016-05-24 17:23
Error: Error building chaincode: rpc error: code = 2 desc = "Error getting chain
code package bytes: code does not exist file /local-dev/src/eNot/file.go is not dir\n"
mcrafols
2016-05-24 17:24
@ghaskins: I'll keep trying tomorrow to see if I am succesful
mcrafols
2016-05-24 17:24
thank you very much!! your help is very much needed!
ghaskins
2016-05-24 17:24
no problem, sorry I wasnt more helpful
mcrafols
2016-05-24 17:25
well it seems that now it gets to the folder
ghaskins
2016-05-24 17:25
(I dont use type=GOLANG and I am typically launching with devmode)
mcrafols
2016-05-24 17:25
still extremely helpful!
ghaskins
2016-05-24 17:46
@mcrafols: my colleague confirmed it is the directory you pass in with -p
ghaskins
2016-05-24 17:46
so, not sure why local-dev didnt work, BUT, in our case the name of the go file was the same as the dir
ghaskins
2016-05-24 17:47
e.g. /local-dev/foo/foo.go as specified with /local-dev/foo
ghaskins
2016-05-24 17:47
perhaps that is part of the story
tsariounov
2016-05-24 18:25
probably, if go builds it, it by default names the executable after the directory. all our cc's are named after the directory.
ghaskins
2016-05-24 18:37
thanks @tsariounov
arnaud
2016-05-24 20:30
Looking at the growing list of issues it's clear that we need to get better at giving people proper guidance as to what ought to be raised as an issue
arnaud
2016-05-24 20:31
having usage questions from newcomers mixed in with real bugs is rather messy

maybe we can update the issue template (https://github.com/hyperledger/fabric/blob/master/.github/ISSUE_TEMPLATE.md) with something like "For general purpose questions, please use [StackOverflow](http://stackoverflow.com/questions/tagged/hyperledger)."
arnaud
2016-05-24 20:50
@sheehan: good idea!
cbf
2016-05-24 21:00
: there are a good number of stackoverflow questions (and some answers) and generally we should all be vigilant and responsive…
cbf
2016-05-24 21:01
I have also noted that when people talk about Hyperledger fabric, they often just shorten it to “Hyperledger"
cbf

I’ve started editing responses and questions when I see this but those need to be peer reviewed http://stackoverflow.com/questions/36910077/where-are-chaincodes-executed/36910078#36910078
arnaud
2016-05-24 22:32
@sheehan: by the way, if you update the template I'd appreciate if you could remove the space that's between the [] for all the things we need to check
sheehan
2016-05-24 22:33
ok
arnaud
2016-05-24 22:33
that way one can simply add an x without having to also delete the space
arnaud
2016-05-24 22:33
if a space is left the formatting doesn't work

I run a chaincode in sanbox environment.
joseph
2016-05-25 02:16
I want to get metadat by calling stub.GetCallerMetadata().
joseph
2016-05-25 02:16
It returns empty.
joseph
2016-05-25 02:17
Is it reasonable for value of the metadata is empty?
muralisr
2016-05-25 02:54
The metadata is something user passes at the time of deployment. It can be anything. So if you didn’t pass anything, it can be empty
muralisr
2016-05-25 02:55
metadata handling is exemplified in fabric/examples/chaincode/go/asset_management_with_roles - both in the chaincode and in the test driver
joseph
2016-05-25 03:00
I got it.
joseph
2016-05-25 03:01
by the way, I verify a signature like this
joseph
2016-05-25 03:02
callerCert, err := stub.GetCallerCertificate();
sigma, err := stub.GetCallerMetadata()
if err != nil {
return false, nil, errors.New("Failing retrieving metadata")
}
payload, err := stub.GetPayload()
if err != nil {
return false, nil, errors.New("Failing getting payload")
}
binding, err := stub.GetBinding()
if err != nil {
return false, nil, errors.New("Failing getting binding")
}
eccLogger.Debug("passed certificate [%x]", adminCert)
eccLogger.Debug("passed sigma [% x]", sigma)
eccLogger.Debug("passed payload [% x]", payload)
eccLogger.Debug("passed binding [% x]", binding)
ok, err := stub.VerifySignature(
adminCert,
sigma,
append(payload, binding...),
)
joseph
2016-05-25 03:03
I always get the verify signature failing.
joseph
2016-05-25 03:04
@muralisr: do you have any idea about it?
joseph
2016-05-25 03:15
why does all information come from one stub but verify itself signature failed?
joseph
2016-05-25 04:48
I saw an API to verify signature.
joseph
2016-05-25 04:48
// VerifySignature ...
func (stub *ChaincodeStub) VerifySignature(certificate, signature, message []byte) (bool, error) {
// Instantiate a new SignatureVerifier
sv := ecdsa.NewX509ECDSASignatureVerifier()
// Verify the signature
return sv.Verify(certificate, signature, message)
}
joseph
2016-05-25 04:48
How do we get the signature to send to the API?
mikezaccardo
2016-05-25 05:12
@joseph we are facing the exact same problem right now!
mikezaccardo
2016-05-25 05:13
it seems to want a DER which is a binary representation, yet we need to POST it in the “metadata” field which requires base64 encoding
mikezaccardo
2016-05-25 05:13
mikezaccardo
2016-05-25 05:14
GET /registrar/{enrollmentID}/ecert
GET /registrar/{enrollmentID}/tcert
mikezaccardo
2016-05-25 05:14
that gets url-encoded certs
joseph
2016-05-25 05:15
we parse ecert to get the signature?

2016-05-25 05:30
@joseph: we drilled down on same code and found derToX509Certificate(certificate) which is fine if called programmatically but as you say we can’t pass binary metadata via POST
mikezaccardo
2016-05-25 05:53
it looks like the intention is not to use the REST API for this example, but instead use the apps: https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management/app
mcrafols
2016-05-25 08:41
@ghaskins: I finally could deploy it!
mcrafols
2016-05-25 08:44
The previous path is a local path relative to $GOPATH in the docker image
mcrafols
2016-05-25 08:45
(that's why yesterday by setting the $GOPATH=local-dev I was able to access my chaincode)
mcrafols
2016-05-25 08:46
It is somewhat confusing that the deploy path is github.com.... because it leads to think that it is getting the chaincode from github but it is really getting a local copy (just that the folder is named http://github.com)
mcrafols
2016-05-25 08:48
I have also tried having a different name in the folder than in the chaincode file and it works
mcrafols
2016-05-25 08:50
Finally, I got the chaincode in the docker image just by making the folder in the vagrant path /opt/gopath/src/github.com/hyperledger/fabric/peer and then building the image (go test -run BuildImage_Peer)
mcrafols
2016-05-25 08:53
I guess that if in the node start it is set -v local-dev:localdev -e GOPATH=/local-dev then the chaincode could be deployed too and it could be accessed from outside the docker image too
nickmelis
2016-05-25 09:13
@mcrafols: that is useful
mcrafols
2016-05-25 09:56

2016-05-26 06:15
could I setup the network environment without varant and docker ? it seems when i start a peer node on machine A using :
peer node start
and start another peer node on machine BS using:
export CORE_PEER_DISCOVERY_ROOTNODE = ip of machine A
peer node start
then i got error on machine B:
panic: Error reading CORE_NOOPS plugin config: Unsupported Config Type ""
do i need some extra procedure to start on bare metal without docker and deploy chaincodes?
joseph
2016-05-26 06:55
is it possible to read data from rocksdb locally?
joseph
2016-05-26 08:39
Can we run asset management example in dev mode? what is a right metadata for that example?
nickmelis
2016-05-26 09:30
what is listening on port 31315? I can’t find anything in the logs but I can see the port is in use by fabric
yingfeng
2016-05-26 11:18
how to deploy fabric to a production enviornment? It seems all the existing documents are sandbox or dev environment on single machine.
ghaskins
2016-05-26 11:41
@yingfeng: I would study the docker-compose files to see what they are setting for each VP
ghaskins
2016-05-26 11:42
@joseph: can you clarify what you mean by “locally"
ghaskins
2016-05-26 11:42
e.g. do you mean from within chaincode? or just from something colocated with the node that runs the vp
ghaskins
2016-05-26 11:43
for the former, no….for the latter, the db is stored in /var/hyperledger/production (by default)
ghaskins
2016-05-26 11:43
(though you would want to be aware of rocksdb-specific rules governing concurrent access
ghaskins
2016-05-26 11:44
i.e. you might only be able to safely open the database if the peer is not actively running
ghaskins
2016-05-26 11:46
@nickmelis: its helpful to grep peer/core.yaml to find that answer
ghaskins
2016-05-26 11:47
@yingfeng: support for production deployments is emerging, the project is too young to have this polished
yingfeng
2016-05-26 11:48
@ghaskins: could I run fabric on multiple physical nodes?
ghaskins
2016-05-26 11:52
of course
ghaskins
2016-05-26 11:52
its just a matter of setup
ghaskins
2016-05-26 11:53
the docker-compose stuff is effectively doing the same things, they are all isolated from one another in terms of filesystem/network/etc
ghaskins
2016-05-26 11:53
so, you could take hints from the docker-compose as to how its configuring the different nodes and replicate that on physical boxes
ghaskins
2016-05-26 11:53
you would just be on your own to actually orchestrate it
ghaskins
2016-05-26 12:04
alternatively, you could try to use docker-swarm to distribute the docker-compose based workload out to physical machines
ghaskins
2016-05-26 12:04
i’ve never tried this, but it should be theoretically possible
yingfeng
2016-05-26 12:05
here is my experiments using calico as docker SDN https://github.com/hyperledger/fabric/issues/1602, but i got wrong when deploying chaincodes
ghaskins
2016-05-26 12:07
i am not an expert in this regard by any stretch, but @corecode is correct, you need to ensure that the deployed peer image can reach the docker daemon since the peer uses docker to isolate chaincodes too
ghaskins
2016-05-26 12:07
seeing it use a unix channel is most certainly a bad configuration, the docker daemon will be running outside the peer container
ghaskins
2016-05-26 12:09
You need to set vm.endpoint, as per https://github.com/hyperledger/fabric/blob/master/bddtests/compose-defaults.yml#L5
ghaskins
2016-05-26 12:10
so that the peer instance running in the container can break out of the container and find the relevant docker controller
ghaskins
2016-05-26 12:10
failing to set this will result in it looking for the daemon via UDS, which will not work
ghaskins
2016-05-26 12:11
i would scrutinize the docker-compose config, its already doing mostly what you need, you just need to port to your environment
joseph
2016-05-26 12:17
@ghaskins: I mean whether I can read directly data from /var/hyperledger/production/db using rocksdb client.
ghaskins
2016-05-26 12:18
i do not imagine you “can’t”, its not like we altered the rocksdb engine
ghaskins
2016-05-26 12:18
whether you can do so safely or in any meaningful way is an exercise for the reader :wink:
ghaskins
2016-05-26 12:20
i dont know rocksdb specifics, but I have worked with a ton of other dbs and most of them might not be happy with multiple concurrent access, so you might need to shut the peer down first
simon
2016-05-26 12:20
yea, i'd like to have a rocksdb cli as well
joseph
2016-05-26 12:21
@ghaskins: I got it.
simon
2016-05-26 12:21
joseph: or do you want to build an application on that?
joseph
2016-05-26 12:21
I want to examine how data ecrypted in rockdbs.
ghaskins
2016-05-26 12:22
@joseph: reading between the lines: are you trying to see how/if peer protects the rocksdb layer itself?
joseph
2016-05-26 12:22
yes.
ghaskins
2016-05-26 12:22
or are you interested in just seeing the raw ledger data
joseph
2016-05-26 12:23
both :slightly_smiling_face:
ghaskins
2016-05-26 12:23
ah, i see…i havent been involved in any of that impl, but I am reasonably certain you are not going to see much in the way of protecting the rocksdb layer
ghaskins
2016-05-26 12:23
note that this is perfectly ok in my mind
ghaskins
2016-05-26 12:23
the threat model is not local access at the peer level
ghaskins
2016-05-26 12:24
the peer environment is considered trusted by the peer, its the network of other actors that is not trusted
ghaskins
2016-05-26 12:24
but as such, the peer code doesnt try to obfuscate neither .text nor .data within the node
simon
2016-05-26 12:25
joseph: why do you want to read the database directly?
ghaskins
2016-05-26 12:26
therefore, it is perfectly acceptable to store data in the local filesystem generally unprotected, and I suspect we do exactly that….the only way to go deeper would be to use HW enclaves, etc
joseph
2016-05-26 12:26
@simon: someone ask me how much security of data on rocksdb does.
ghaskins
2016-05-26 12:26
but we dont do that today
simon
2016-05-26 12:26
joseph: what?
ghaskins
2016-05-26 12:26
the security is derived from the node itself, not the rocksdb layer
simon
2016-05-26 12:26
i don't understand that sentence
ghaskins
2016-05-26 12:27
@joseph: the node is a black box accessible via port 31315…all of the security is derived from that
joseph
2016-05-26 12:27
@simon: I mean that someone ask whether hacker reading directly data from rocksdb.
ghaskins
2016-05-26 12:27
(or whatever the grpc channel is, cant recall)
simon
2016-05-26 12:27
ah
yingfeng
2016-05-26 12:28
my mistake. After I set CORE_VM_ENDPOINT=http://172.17.0.1:2375, the chaincode deploy will not meet error outputs, but when I use restful apis as invoke/query, the peer will report (Error starting container: no such image), and i did not see chaincode images have been created
simon
2016-05-26 12:28
well, intruder having local access to the machine = pwnd
ghaskins
2016-05-26 12:28
@simon: well, hold on, not quite
joseph
2016-05-26 12:28
@ghaskins: your information is very useful. I should read it carefully.
ghaskins
2016-05-26 12:28
rocksdb does nothing to add security, yes
ghaskins
2016-05-26 12:29
but you arent necessarily completely pwnd…heh
simon
2016-05-26 12:29
joseph: all data of the local peer is accessible if you have access to rocksdb
ghaskins
2016-05-26 12:29
just pwnd w.r.t. info that the particular VP may have been privy too
simon
2016-05-26 12:29
yea
ghaskins
2016-05-26 12:29
if the VP was not in the endorser scope, that is still safe
ghaskins
2016-05-26 12:30
but I think we are in agreement
ghaskins
2016-05-26 12:30
@yingfeng: im guessing you do not have the basemage deployed perhaps
ghaskins
2016-05-26 12:31
@joseph @simon I think its safe to say generally that the security is derived at the network level (and this is ok, IMO)
yingfeng
2016-05-26 12:31
@ghaskins: only hyperledger-peer is not enough ?
ghaskins
2016-05-26 12:32
until we have an enclave like solution, anyway
joseph
2016-05-26 12:32
@ghaskins: I got it.
yingfeng
2016-05-26 12:32
this is the output of `docker images`:
hyperledger-peer latest 0f28d42a3384 About an hour ago 1.963 GB
ghaskins
2016-05-26 12:33
you could try to further encrypt the db, but that is security theater without using a HW protection
ghaskins
2016-05-26 12:33
@yingfeng: yes, you need to have hyperledger/fabric-baseimage:latest on those nodes too
ghaskins
2016-05-26 12:33
note that this is a synthetic image that is generated by “make base-image"
ghaskins
2016-05-26 12:33
e.g. you wont find it on dockerhub
ghaskins
2016-05-26 12:34
the chaincode layer will base its isolation on that image
ghaskins
2016-05-26 12:34
i suspect that is what you are running into now
joseph
2016-05-26 12:36
@ghaskins: I'll try it. Thank you so much. I have a better understanding.
yingfeng

These are outputs of peer node.
simon
2016-05-26 12:42
you will have to set the loglevel to DEBUG

@yingfeng the 'no such image' error may also mean that there's an error in your chaincode which caused it to fail to build.

Hi, @baohua , I applied your patches actually but did no help~, it's just an extra configuration.

actually, when u use overlay, you will meet this issues, but from your configuration, seems there’s also other problem. will reply u later.
yingfeng
2016-05-27 01:48
Actually, I created the dockernetwork with name of "net1", and when I use "net1" in the configuration `containerNetworkmode`, the chaincode container could not be even created.
yingfeng
2016-05-27 01:50
So the above outputs(in issue 1583, chaincode image was created, but query failed) still belong to the situation of `containerNetworkmode: host`

can someone please point me in the direction of some chain code examples? I looked at the chaincode_example02.go but I was wondering if there were others. Is it possible to hit an HTTP end point from a contract?
ghaskins
2016-05-27 02:34
did you see the others along side example02?
ghaskins
2016-05-27 02:34
as far as HTTP access, the short answer is “no"
ghaskins
2016-05-27 02:34
the long answer is, this will probably “work” if you try it today, as we are not locking down the container very much
ghaskins
2016-05-27 02:35
but a) this will change eventually, and b) its a really bad idea regardless w,r,t, deterministic responses from the chaincode
ghaskins
2016-05-27 02:36
rather, try to think about injecting whatever state/data to the contract, rather than the contract pulling the state/data in
iamsamwood
2016-05-27 02:42
@ghaskins makes sense, thank you!
iamsamwood
2016-05-27 02:44

How to login to peer network in development mode ? I used the configuration (e.g. <fabric-path>/bddtests/docker-compose-4-consensus-classic.yml ) to setup my development network in localhost, then try to login to each peer. I was able to login one of them, but others failed like:
```$ curl -X POST 172.17.0.5:5000/registrar --data '{"enrollId": "test_user0", "enrollSecret": "MS9qrN8hFjlE"}'
{"OK": "Login successful for user 'test_user0'."}
$ curl -X POST 172.17.0.6:5000/registrar --data '{"enrollId": "test_user0", "enrollSecret": "MS9qrN8hFjlE"}'
{"Error": "rpc error: code = 2 desc = 'Identity or token does not match.'"}
$ curl -X POST 172.17.0.3:5000/registrar --data '{"enrollId": "test_user0", "enrollSecret": "MS9qrN8hFjlE"}'
{"Error": "rpc error: code = 2 desc = 'Identity or token does not match.'"}
$ curl -X POST 172.17.0.4:5000/registrar --data '{"enrollId": "test_user0", "enrollSecret": "MS9qrN8hFjlE"}'
{"Error": "rpc error: code = 2 desc = 'Identity or token does not match.'"}```
Is there anything I need to setup to use muliple peers ? I'm trying to setup 4 apps. Each try to access peers (e.g. vp0, vp1, vp2, vp3) in dependently.

I noticed with different user name, I can login to each peer. Maybe restriction in devnet setup.

What's the possible reason why chaincode has not been registered after successfully creating ? For this issue https://github.com/hyperledger/fabric/issues/1602

is there an easy way to include fabric-api in your Java project?
nickmelis
2016-05-27 08:54
I’m trying to get it up and running but finding a lot of problems
nickmelis
2016-05-27 08:55
it would be great to be able to use fabric-api rather than having to create another protobuf client
ibmamnt

@yingfeng: Maybe, peer address is not passed to chaincode executable well. Mine is like this.
```
$ docker inspect <chaincode-container>
"Cmd": [
"/opt/gopath/bin/6a5e8de94d239722c0529b6998969e3dd83e5e536035e6d1d6b093878d481f9f78c7502c295b0104ca7c69d7625ed3b6f6968a6fe469a5f1299e25dee9b5cfca",
"-peer.address=172.17.0.3:30303"
],
```

I pull the latest code with commit of "a11ce403cbad1f5cd90bd807de0c65eaf226f9a3", and rebuild the fabric image, then it could work! The previous image was built using code just 1 day before, I've not found relationship between several latest commits and the networking issue I reported..

2016-05-27 11:03
@ibmamnt: the issue here is actually not a devnet restriction it is due to the way the APIs actually work and what they do. When you call the REST APIs to register / login users against a peer, the peer then basically acts as a client on your behalf (kind of like a wallet). So the peer itself actually calls all of the membersvcs APIs under the covers and essentially downloads all of the enrollment material locally. `enrollSecret` is basically a one time use token, so when you login to the first peer, that `enrollSecret` cannot be used again hence the failures and also the reason why you can use a different enrollID / enrollSecret against each peer and things work. There is a new NodeJS SDK which is coming out which will use the "native" API and have wallet like functionality. In that case, you'll be able to point the client at multiple peer using the same credentials. Hope this helps
yingfeng

I setup a simple stress testing environment, and the single peer node even hangs under a relative higher pressure, and could not recover anymore. https://github.com/hyperledger/fabric/issues/1627

2016-05-27 19:02
then I will update the PR against fabric to use that for the test
ghaskins

@ry, it would be a directory copied from hyperledger/fabric, so not really a .git repo ready to go
arnaud

right, it's just some chaincode example we need to reside in a different repo for testing purposes

unforunately, no…but fortunately the stuff that does need to go in is pretty straight forward
arnaud

yeah, it's just a few files
arnaud

ghaskins

unless I am misunderstanding, i think it will be minimal…the imports that it declares will be stuff like …/shim and that is fine to draw from the other official repo IMO
arnaud

agreed
sheehan
2016-05-27 19:05
I feel like the name of that repo is a bit confusing. I’d expect the tests to be in there, but they’re not

arnaud
2016-05-27 19:14
ah, ok

2016-05-27 19:15
or I could clone fabric, since fabric-test is a subset of fabric, right?
arnaud

yeah but it's going to bring in too much stuff

sheehan
2016-05-27 19:19
Is this really a unit test? As you’re contacting a running peer, I don’t think any of these tests contribute to the `go test -cover` result.
sheehan
2016-05-27 19:28
as for the name of the repo, “fabric-test-resources” or “fabric-test-assets” ? I also wouldn’t mind having a nice chaincode with it’s own repo, something a bit more flushed out than chaincode_example01. Like a “hello-chaincode” repo or something like that
ghaskins
2016-05-27 19:31
all sounds good to me
ghaskins
2016-05-27 19:32
I didn’t understand the comments you made about it possibly not being a unit test though
ghaskins
2016-05-27 19:32
IIUC, its invoking the deploy path with an http based path, which should increase coverage I would imagine
ghaskins
2016-05-27 19:33
(since to my knowledge we didnt have anything testing http based deploys)
ghaskins
2016-05-27 19:33
but maybe I am misunderstanding
ry
2016-05-27 19:40
OK. https://github.com/hyperledger/fabric-test is created with the initial content suggested.
ry
2016-05-27 19:40
if you want another repo name or something, just get @cbf to bless it and it’s easy enough to make happen
sheehan
2016-05-27 19:43
@ghaskins: oh, it’s possible I’m wrong. I believe at least some of these tests need a peer to be running. I thought the test was contacting that peer and that anything on the “server” side was not included in the test coverage
ghaskins
2016-05-27 19:44
thats a good question, i thought these tests executed in unit-test context and not against a peer
ghaskins
2016-05-27 19:44
but I might be wrong
kostas
2016-05-27 19:44
before I create an issue for this, who is the intended audience for the Travis CI README that's in the repo?
kostas
2016-05-27 19:45
it seems like the first three quarters of the document are addressed to the repo maintainers - why are the developers exposed to this info?
kostas
2016-05-27 19:46
I'd argue that the only relevant info to them is towards the end; the "How to skip Travis Build execution for PRs?" section (which probably belongs to either `CONTRIBUTING.md` or `docs/dev-setup/install.md`)
ry
2016-05-27 19:49
kostas: probably rename the whole travis ci readme? we’re working on getting jenkins up and running so it may soon be obviated regardless
arnaud
2016-05-27 19:56
@sheehan: that new test doesn't depend on a running peer, it's self contained
arnaud
2016-05-27 19:57
and it should increase coverage because it uses the getCodeFromHTTP function of hash.go which isn't tested at all otherwise
arnaud
2016-05-27 19:58
I do like your suggestions for the name of the repo
arnaud
2016-05-27 19:59
-resources sounds slightly better to me
arnaud
2016-05-27 19:59
for some reason
sheehan
2016-05-27 20:08
@arnaud: ah, ok. good to know it’s self contained

> Chain Auditor - Entities with the permission to interrogate transactions.
(Ref: https://github.com/hyperledger/fabric/blob/master/docs/glossary.md )
'endorser' seems to do endorsement (typically found in linkedin - which assures like this person has this skills, I gurantee, something like this). So I think 'audit' and 'endorser' are quite different as far as I read the document.

B: as a slight riff, we could do os packaging (though I know that idea had some resistance in the past regarding deps, so perhaps similar sentiment would be directed at product
ghaskins
2016-05-31 18:24
one unknown with packaging would be how docker images are managed, though
ghaskins
2016-05-31 18:24
(today we download/build them as a product of the software build system, which is slightly different than how os packages tend to work

C: sounds fine, though it could just be a releasenotes.txt too, whatever works best
ry
2016-05-31 18:26
also, on other projects I do something like git merge —no-ff origin/RB16.04 about once a day in a release cycle so master is never too far behind RB
ghaskins
2016-05-31 18:26
:anguished: i have no strong opinion on other than to say its probably too early/premature to commit to any kind of LTS

ghaskins

ghaskins
2016-05-31 18:29
regarding B, it might be the most natural fit to target docker, at least for now
cbf
2016-05-31 18:29
suggest we use wiki for releases complete with release notes… as a log of all releases
ghaskins
2016-05-31 18:29
we would have to beef up a pipeline to push to dockerhub though, right now its very manual
binhn
2016-05-31 18:34
@cbf it would be the wiki of the branch, right? or on the fabric, we would create a page “releases” and have an entry for each release?
cbf
2016-05-31 18:35
no, wiki off the fabric repo
binhn
2016-05-31 18:35
@ghaskins: is that the pipe from CI (or Jenkin) build to dockerhub?
cbf
2016-05-31 18:35
so yes, wiki page called “releases” linked from top level page
binhn
2016-05-31 18:36
ok, got it
ghaskins
2016-05-31 18:39
@binhn: exactly
ghaskins
2016-05-31 18:39
ideally have some CI pipeline that can react in an intelligent way, build the assets and push them out
ghaskins
2016-05-31 18:39
e.g. perhaps in response to release tags
ghaskins
2016-05-31 18:40
right now, i have to do them all by hand…its not terrible because we only publish the base image and it changes infrequently, but that wont be the case if we decide to use docker more generally
binhn
2016-05-31 18:43

@ry: do you know if our jenkins has a big pipe to dockerhub?

binhn: define big pipe? if we’re publishing huge artifacts we (LF) usually will set up a Nexus server or similar locally
binhn
2016-05-31 18:54
enough to push a few gigabytes — an image is a little more than 1G and we need to push several

2016-05-31 18:57
I suspect a Nexus system would be better. the Jenkins could publish to Nexus directly and then update dockerhub. are we going to be pulling from dockerhub on every build?
binhn

no, the build caches the base images

I have some questions on the consensus design:
1. If I setup two peer nodes as the initial fabric network, after some time, I wanted to add the third peer node into the fabric network, will the third peer node have the consistent state with existing two peer nodes?
Since each peer is a replicant, the new peer node should synchronize data from existing peer nodes to keep the state consistency, however, I do not see such behavior, the new peer will return different query response with the existing one.
2. If I post `invoke` approaches to multiple peers concurrently, according to the consensus protocol, the eventual state of each node should be consistent, right?
However, this is my test: I post stress `invoke` requests to `peer1` and `peer2`, then stop the requests. After some time(aim to wait for the nodes to reach consensus), I send query request to both peer nodes, but I've got different value. It seems replication state machine is not ready under current design.
kostas
2016-06-03 06:46
@yingfeng: #1 we don't support dynamically adding validators yet, this is coming a bit later on. #2 doesn't sound right though. which consensus plugin do you use?
yingfeng
2016-06-03 06:46
@kostas: I am using the default consensus plugin---`pbft`
yingfeng
2016-06-03 06:47
If I sent single invoke query to peer nodes, I can get consensus result. But my experiment is to perform the stress testing on multple peer nodes concurrently
kostas
2016-06-03 06:48
can you try this experiment with N=4 peers and report back?
yingfeng
2016-06-03 06:49
sure, do you mean I try it in N=2 and N=3 peers is not correct ?
kostas
2016-06-03 06:55
won't say that just yet; I want to reproduce this locally first (am traveling now, will have access to a laptop in ~12h)
yingfeng
2016-06-03 09:14
@kostas: I setup 4 peers, and perform stress `invoke` requests on two peers, after finished, then I send query request to each peer, and found each peer will return a different state

Is there any work being done to implement a db other than rocksdb at the moment? I came across this, https://github.com/hyperledger/fabric/issues/839, and though it would be useful for the sake of choice to make it easy to implement any type of db that a user would like. Abstracting the data interface would have to be done to get rid of some of the proprietary rocksdb code so that any db can work but would anyone object to this? Are we planning on just sticking with rocksdb in the long run?
greg_not_so
2016-06-03 19:08
i don't see a reason to limit the project to only one db, so if redis and others want in, why not let them?

Hello guys!
cbruguera
2016-06-07 13:12
I have a question... I'm quite a blockchain newbie, but I'm researching into different technologies since I am building a platform for management of identities and KYC.
I was told that IBM OBC was a good choice for us, and I'm barely at the beginning of my research... Is IBM OBC somehow "deprecated" now? Is HyperLedger fabric the thing I should be looking for?
simon
2016-06-07 13:14
obc was donated as hyperledger fabric
simon
2016-06-07 13:14
so that's the thing to look at
cbruguera
2016-06-07 13:14
Thank you very much
cbruguera

I'll probably be asking some more questions later, since I'll be getting started with fabric soon.

@dianfu: regarding status, I don’t know. I am just the feature requester :wink:
dianfu
2016-06-07 13:43
ok. thanks a lot.:grinning: Is there any other way to identity a user's identity in chaincode?
dianfu
2016-06-07 13:45
with tcert, seems that it's difficult to do so.
ghaskins
2016-06-07 13:53
to be clear, that is the point :wink:
ghaskins
2016-06-07 13:53
if the user identity isn’t important to mask, you can always opt to have the ECERT id included
ghaskins
2016-06-07 13:54
i think support in general for any of this is still emerging however
ghaskins
2016-06-07 13:55
what I was asking for was something in the middle…stable id for the purposes of chaincode function, but obfuscated true-identity from the perspective of unprivileged entities
nickmelis
2016-06-07 14:01
I’m using fabric via JSON api and trying to experiment with permissioned blockchain
nickmelis
2016-06-07 14:02
the first option is to pass a “securecontext” username
nickmelis
2016-06-07 14:02
and it has to be configured in membersrvc.yaml if I’m not mistaken
nickmelis
2016-06-07 14:03
with the registrar API I can login and get tcert and ecert, but how can I use those certificates when invoking/querying chaincode?
ghaskins
2016-06-07 14:05
nickmelis: the only way I know how to right now is via the SDK
ghaskins
2016-06-07 14:05
./sdk/node
ghaskins
2016-06-07 14:05
though im sure the protocol could be emulated if you really wanted to
nickmelis
2016-06-07 14:06
but there’s no option to use it via JSON API right now, correct?
dianfu
2016-06-07 14:08
The rest api in peer node currently use TCert to construct the transaction. If I want to use ECert, I have to construct the transaction by myself. Is my understanding correct?
dianfu
2016-06-07 14:11
seems that there is no switch to let user choose whether to use ECert or TCert in the rest API.
ghaskins
2016-06-07 14:11
@nickmelis: not sure, you could look at how the SDK does it I suppose
ghaskins
2016-06-07 14:11
@dianfu: my understanding is that ecerts can not be used directly in a txn
ghaskins
2016-06-07 14:12
IOW, you always use a tcert, with varying level of detail exposed between the ecert/tcert
nickmelis
2016-06-07 14:15
@dianfu: is there a way to pass the TCert in the JSON request through the API rather than the “securecontext” ?
nickmelis
2016-06-07 14:17
looking at the API definition here -> https://github.com/hyperledger/fabric/blob/master/docs/protocol-spec.md#6213-chaincode-api
binhn
2016-06-07 14:17
@nickmelis: JSON RPC API doesn’t allow passing TCert, but it automatically selects a TCert for the transaction. You should look at the client SDK, which has more flexibility
nickmelis
2016-06-07 14:18
ok so all the users are in the yaml file, right?
nickmelis
2016-06-07 14:18
based on that, the sdk creates and sends ECert/TCerts
binhn
2016-06-07 14:19
there’re Membership Services API to add users, but the easiest way to test is to stick the users into the yaml file
nickmelis
2016-06-07 14:19
@binhn: when you say Membership API are you talking about the /registrar API?
binhn
2016-06-07 14:20
no, it’s gRPC api; let me find the doc
nickmelis
2016-06-07 14:20
ah right
binhn
2016-06-07 14:20
nickmelis
2016-06-07 14:21
so I would need a gRPC client right?
binhn
2016-06-07 14:21
the client SDK (javascript) provides that
binhn
2016-06-07 14:21
or you can use other languages that support gRPC
nickmelis
2016-06-07 14:22
is there any Java gRPC client out there?
nickmelis
2016-06-07 14:22
or should I build my own one?
nickmelis
2016-06-07 14:23
I think fabric-api was an attempt towards that direction, but I’ve never managed to get it up and running
binhn
2016-06-07 14:23
you can build your own or look at the Java Fabric project to contribute
nickmelis
2016-06-07 14:23
who’s developing the fabric-api project atm?
binhn
2016-06-07 14:24
mainly @tamas
nickmelis
2016-06-07 14:27
ok thanks. It would be interesting to know if there is a roadmap and what developments are planned for fabric-api
nickmelis
2016-06-07 14:28
and also how the other guys here use fabric-api. I would like to just import it as an external library into my Java project
dianfu
2016-06-07 14:31
@ghaskins: Thanks very much. So your feature request about a certificate between ECert and TCert is very useful. Without it, it's very difficult to identity a user's identity and so it would be unable to do access control in chaincode.
binhn
2016-06-07 14:51
@dianfu: you might want to take a look at this doc https://github.com/hyperledger/fabric/wiki/Attribute-Certificate-Authority
dianfu
2016-06-07 15:17
@binhn: Thanks a lot for your sharing. An interesting feature. While it seems that it's still in discussion or in development? I cannot find any code related.

What is the upper limit for how much data can be stored in a chaincode’s state and is it all managed in peer's memory ?
nkunkel
2016-06-08 06:13
During chaincode deployment I keep running into the error:
[chaincode] chaincodeSupport -> DEBU -2d handler not found for chaincode /home/ibm/loyaltyBank.go:0.0.1
Does this mean fabric can't find my chaincode source file? Does the path supplied for the -p argument during chaincode deployment not use absolute paths?

when I POST to the /registrar API, does the user I am using have to be configured in membersrvc.yaml first?
gengjh
2016-06-08 09:38
currently, the answer is yes I think. As I know there is plan to manage the users via system cc.
nickmelis
2016-06-08 09:40
someone was talking about the ability to add users via API, but I think it’s only viable via gRPC at the moment
gengjh
2016-06-08 09:40
yes. only gRPC for now

Hi, is there any script to calculate currentBlockHash value of specific block ? I'm aware <rest-url>/chain will produce currentBlockHash and previousBlockHash. But /chain/blocks/{block} will not print out blockhash itself. Say, if the height is 100, I'd want to calculate Blockhash of block '98 ' to verify previousBlockHash value of latest block ('99') is valid.
simon
2016-06-09 09:44
ibmamnt: i think the REST interface should return the hash itself

Morning all; I've created a Go module to help out with the boilerplate involved in parsing arguments that are passed in to chaincode from REST calls: you register a function (with a standard typed parameter list) and the module parses all the arguments from `args []string` into built-in types, or unmarshals them from JSON, and calls the function with them. Is there any interest in this? Where can I submit this? Sorry if this isn't the right channel to ask in.
ghaskins
2016-06-09 15:10
@pschnap: I’ve been working on something similar (https://github.com/ghaskins/chaintool). Perhaps we can collaborate
ghaskins
2016-06-09 15:11
mine works with dynamic code generation rather than a module, though
pschnap
2016-06-09 15:52
@ghaskins: interesting looking project! (Surprised me to find it's written in Clojure!) My module seems like it would fit in the back-end for Go implementations generated by your code -- whether it should be part of your project or part of the hyperledger itself is difficult to say, thought it seems like it might fit better in the hyperledger project directly. As for collaboration, this was just something that I wrote while I had some down-time between project tasks and I don't know what I'll be tasked with next -- hyperledger isn't my primary project.
ghaskins
2016-06-09 15:53
@pschnap: note that I have made a recent proposal to include chaintool in the hyperledger code base…i think it will be reviewed at next weeks TSC call

nkunkel
2016-06-09 16:46
@mcrafols I had forgotten to set the OPENCHAIN_CHAINCODE_ID_VERSION and OPENCHAIN_PEER_ADDRESS parameters. I'm still not 100% sure how the peer address works, but I believe it routes the calls to the chaincode's "symbolic" urls to the peers with the "physical" paths of the chaincode. For some reason directly giving the absolute physical paths directly in the chaincode url does not work.
mcrafols
2016-06-09 16:47
I think the path is relative to $GOPATH/src
mcrafols
2016-06-09 16:50
@nkunkel: are you using openchain?
nkunkel
2016-06-09 16:50
Yes
nkunkel
2016-06-09 16:51
It's an openchain project I inherited and trying to get it to work with fabric has broken too much stuff to make it worth it.
nkunkel
2016-06-09 16:53
I'm aware the path was relative to $GOPATH/src, I stored my chaincode relative it but still no dice. May have been a bug with the version of openchain I'm using.
cbf
2016-06-09 17:36
@nkunkel: openchain has been deprecated for a while… you may want to fork/clone the hyperledger/fabric repo and build a new environment https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/install.md
nkunkel
2016-06-09 17:40
In the future I will, but for now I'm stuck with this and a looming deadline =/
markparz
2016-06-09 20:51
@nkunkel: Can you give us more information on the deadline? We would like to clean out that repo to make sure nobody else uses that extremely old code, but don’t want to pull the rug out from under you
nkunkel
2016-06-09 20:53
Could someone help me diagnose an error. I'm sending a GET request from a node.js client to Openchain.
Get the following error back:
STATUS: 404
HEADERS: {"access-control-allow-headers":"accept, content-type","access-control-allow-origin":"*","content-type":"application/json","date":"Thu, 09 Jun 2016 20:41:41 GMT","content-length":"42","connection":"close"}
DATA: {"Error": "Openchain endpoint not found."}
Any ideas? Seeing as this is an Openchain supplied error, that means we're connecting to the chaincode server correctly, but we're not able to identify the specific chaincode I'm trying to query? Or could it identify the correct chaincode, but could not find the specific function within it I'm trying to query?
nkunkel
2016-06-09 20:55
It's a demo for LinuxCon. I think the sales guys might want to use it for client demos at some point, but I think we'll just have them connect to my current machine and won't need to provision new ones.

2016-06-09 23:42
it's just the query function that is giving me the error.

mrshah
2016-06-10 12:37
AFAIK - Duplicate Handler Error can be ignored. This might happen due to grid networking & discovery. The peer might be dialing again to the same peer when it discovers it through multiple peers
bcbrock

@iamsamwood: how are you trying to run this? via the REST API or the peer cli?
garisingh
2016-06-11 21:18
unfortunately, I don't think you can do it either of those ways. You'll want to check out https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management/app which uses a native Go client to deploy and invoke the chaincode
garisingh
2016-06-11 21:19
once the new NodeJS SDK is done, you should be able to do this via a NodeJS app though
iamsamwood
2016-06-11 21:24
@garsingh i was trying both, but didn't try the SDK thank you!
garisingh
2016-06-11 21:25
https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management/app definitely works as well - just a Go client version
garisingh
2016-06-11 21:26
you'll see in app_internal.go a deployInternal function which sets the metadata for the deploy transaction
iamsamwood
2016-06-11 21:26
okay great

2016-06-11 21:26
i assume the dev VM has all the deps i need to run this?

@garisingh: it looks like the docs are out of date, they refer to https://github.com/hyperledger/fabric/blob/master/consensus/docker-compose-files/compose-consensus-4.md which is gone--are there still docker-compose files for launching a small network

Does anybody have worked on to compile .proto files in fabric into python ? I did some initial test like:
```protoc --python_out=/tmp/python --proto_path=/usr/include -I=. fabric.proto```
And create a small python program, but failed like:
```$ python test.py
Traceback (most recent call last):
File "test.py", line 2, in <module>
import fabric_pb2
File "/home/amnt/tmp/fabric_pb2.py", line 16, in <module>
import chaincode_pb2 as chaincode__pb2
File "/home/amnt/tmp/chaincode_pb2.py", line 17, in <module>
from google.protobuf import timestamp_pb2 as google_dot_protobuf_dot_timestamp__pb2
ImportError: cannot import name timestamp_pb2```
The purpose is to add dump feature for restapis (e.g. /transactions/{txuuid}) result. e.g. "payload". Dump to something like:
``` transaction = transaction = fabric_pb2.Transaction()
transaction.payload = '<returnvalue-of -resultapi>'.decode('base64')
print transaction.payload```
ibmamnt
2016-06-14 07:13
Or in other word, dump utility of protocol buffer message enbbeded in the result of restapi are actually fine for me.

jonathanlevi
2016-06-14 15:28
(Good morning) @david.acton Give me a use-case please?
jonathanlevi
2016-06-14 15:29
It might be a bit more than merely having a few `membersrvc` servers running. Is it for load-balancing? Do you want them fully in synch?
david.acton
2016-06-14 15:40
@jonathanlevi: It’s mainly for redundancy. If I have a "mission critical" application that requires 99.9% uptime and I have a membersrvc on one node/machine/data centre and any of those components should go down, I cannot perform any of the membership services while that node is offline. If I’m able to have redundancy, I can mitigate against machine/data centre failures. I’d like a membersrvc nodes to act like the rest of the validating and non-validating nodes and replicate themselves.
jonathanlevi
2016-06-14 15:41
OK, thanks for the info! So a few things.
jonathanlevi
2016-06-14 15:42
1. Redundancy in terms of replicated `membersrvc` servers... (let's call them CAs going forward, easier to type ;-))
jonathanlevi
2016-06-14 15:42
is not supported at all. I can tell you right away.
jonathanlevi
2016-06-14 15:43
There isn't a RAID type/back-end syncrhonization process, which allows changes to propagate.
jonathanlevi
2016-06-14 15:43
2. However, that said, you can use more than one server to 'split the load' by having multiple CAs.
jonathanlevi
2016-06-14 15:44
Say, by region/responsibility or some other form(s) of grouping.
jonathanlevi
2016-06-14 15:45
3. Another alley worth exploring is understanding why you need the `membersrvc` uptime. In a way, when looking at the ECert/TCert (and ACert) design...
jonathanlevi
2016-06-14 15:46
(for Enrollment-, Transcation and Attribue- Certificate), you can work in a relatively asynchronous mode, if you pre-generate the certs that you would need.
jonathanlevi
2016-06-14 15:49
----
That said, and I'm really being careful here, not to over-sell... we/some of us are spending a considerable amount of time to make the CAs more of a set of standalone process, preparing also for a pretty intense set of stress testing, looking into the scalability and performance... but also the resiliency and stability, which sound like your main concerns too!
jonathanlevi
2016-06-14 15:50
I hope to be able to give you some more numbers by the end of this week, or towards the beginning of next week... but you are more than welcome to get in touch and share some of your numbers/performance/set up/etc... and we can take a look into more specifics.
jonathanlevi
2016-06-14 15:51
Don't know if I answered your question (too directly/discouragingly) or otherwise? Because I would really encourage you to try it, and provide us feedback.
cbf
2016-06-14 15:52
thanks very helpful
david.acton
2016-06-14 15:55
@jonathanlevi: Thanks so much for your response!! That is very useful information. I understand that CAs don’t need to be up on such a high level, but what is the consequence at the moment if one is destroyed though an act of God or a bad actor? So I have a CA that does Europe and it’s destroyed, what are my options then?
jonathanlevi
2016-06-14 15:56
OK. So there are two ways to think about such scenarios:
1. Act of God: say CA (let's think about VeriSign, for example. WLOG) is not available.
jonathanlevi
2016-06-14 15:57
In that case, if Verisign is offline and cannot issue new certificates (think SSL certificates) for web-servers, then it's not really the end of the world, right?
david.acton
2016-06-14 15:57
cool.. understood
jonathanlevi
2016-06-14 15:57
They just don't accept new CSR (Certificate Signing Requests)/issue new certs.
jonathanlevi
2016-06-14 15:57
OK. Number 2
jonathanlevi
2016-06-14 15:58
2. A bad actor/player. Here the concern is how to revoke someone's public key actually, right?
david.acton
2016-06-14 15:58
correct
jonathanlevi
2016-06-14 15:59
Either by using CRLs (Certificate Revocation Lists) or another mechanism... to be very honest? The CAs don't support CRLs interactively just yet.
jonathanlevi
2016-06-14 16:00
We have the mechanics, in place, for one to be able in the future to verify a (E/T/A) Certificate... but while this will be more secure in some way, it won't scale as such.
jonathanlevi
2016-06-14 16:01
My preference is to have a customizable policy. That is:
jonathanlevi
2016-06-14 16:01
You should be able to configure in a granular way, how you choose to validate certificates before accepting them.
jonathanlevi
2016-06-14 16:02
It will give you the ability to check once a week/day or so, that nothing was revoked (still, not too much load in terms of stability)
jonathanlevi
2016-06-14 16:02
That's one end of the spectrum.... or on the other hand, verify everything...
jonathanlevi
2016-06-14 16:03
... in which case, keeping a side DDoS attacks, etc, will really make you bound to the uptime of the CAs (which is probably what you were asking about earlier on).
jonathanlevi
2016-06-14 16:04
If I could choose (and I don't know enough about the application), I tend to prefer something in between.
jonathanlevi
2016-06-14 16:04
Verify that stuff in not revoked, periodically (but not for every Cert/request), but also statistically, check from a time to time....
jonathanlevi
2016-06-14 16:04
---
jonathanlevi
2016-06-14 16:05
Another related question: How many CAs/nodes do you envisions deploying? Are they all in your control (at least, at first)?
jonathanlevi
2016-06-14 16:06
What's the Transaction/Enrollment request ratio (roughly estimated, etc.). These parameters can help you choose/configure the right policy...
david.acton
2016-06-14 16:12
@jonathanlevi: Thanks again for the information!!! very very useful. I’m still getting my head around this in detail, but the customizable policy sounds good.
jonathanlevi
2016-06-14 16:14
OK. Please feel free to ask away as you are learning this. I'll just throw one last thing at you...
david.acton
2016-06-14 16:14
sure
jonathanlevi
2016-06-14 16:14
Client Authentication can also help reduce load.
jonathanlevi
2016-06-14 16:16
So in some cases, it is quick for the server to not accept connections from nodes if they don't authenticate well. If you are able to know enough about the nodes, etc (again, subject to your deployment), that's also something to look it. Not always possible (e.g. some versions of, IoT/mobile/roaming too frequently, of course... really a function of how much control you have on the nodes, and whether or not you can make it a smooth(er) process to enroll). CAs do support various levels of delegated roles (e.g. a "registrar" role that can accept new enrollments, etc.)
jeroiraz
2016-06-14 16:47
@david.acton, Just adding some extra info to the ongoing discussion with @jonathanlevi:
CAs don't hold in-memory state: all required data is persisted into a relational db.
You should be able to use a DB of your choice as there are no vendor-specific sql statements being used. You could have a replicated db and schedule backups as you consider appropriate, so if a CA goes down, it could be easily restarted without sync delays.
jonathanlevi
2016-06-14 16:55
Yes, we can probably move the DB settings to the configuration, so that one can replace the DB easily. At the moment we have sqlite3 in the code. But it will be easy to move out.

Hi all,
Has anyone had success developing chaincode that imports vendored Go packages which are also imported (and vendored) by fabric itself? (I'm developing my chaincode outside of the fabric repo).
For example, I want to define a function to manipulate the result of `stub.GetTxTimestamp()`. The result type is `gp.Timestamp` which is imported from `"google/protobuf"`.
If I add the line `gp "google/protobuf"` to my chaincode program import lines, and add the `vendor/google/protobuf` (and its dependency `vendor/github.com/golang/protobuf`) dir to my repo, I get the following error about the colliding types:
```
./example.go:77: cannot use timestamp (type *"http://github.com/hyperledger/fabric/vendor/google/protobuf".Timestamp) as type "org/example/vendor/google/protobuf".Timestamp in argument to isOK
```
The reason here is that I'm importing `shim` as a library, but Go libraries should not have a `vendor` dir (but fabric has a `vendor` dir because it is also an executable). If this is not clear I can open a Github issue with a proper code example.
simon
2016-06-14 17:13
yea that doesn't work
simon
2016-06-14 17:13
you can't really use a package that uses vendoring
simon
2016-06-14 17:14
exactly because of these type compatibility issues
dmurik
2016-06-14 17:15
@simon: I assume a proper solution would be to create a new `hyperledger/fabric-shim` project which includes only the shim package, without vendor. Then chaincode program should only import that package.
simon
2016-06-14 17:15
yes
dmurik
2016-06-14 17:15
@simon: It might also make the chaincode docker containers a bit smaller, on the way.

2016-06-14 17:17

Hello guys! I'm reading the hyperledger fabric protocol specs and it's surely an interesting project. Very comprehensive and elegantly designed.
However, I don't see much mentioning about digital currencies or other assets over the hyperledger fabric. Am I missing something? ...I know this is intended as a framework for more general blockchain applications, but what if I want to build an incentivized network with hyperledger? Is this not suitable for cryptocurrencies?

@cbf: I opened Github issue 1832: https://github.com/hyperledger/fabric/issues/1832 . Also suggested there to "hide" the protobuf internals - for example, GetTxTimestamp should return a standard Go time.Time that doesn't require another dependency.

sheehan

it depends on what you need to audit. If it possible to include the information you need to audit in the transactions (the args of the chaincode) and then the chaincode verifies those args and makes the necessary changes to the state, it may be possible to only look at transactions when auditing past history. This is would be similar to bitcoin.

Hi, I'm a newbie here. Trying to understand how transactions are implemented. I see that when a 'invoke' function is called, the args contain the data (or world state) that is written to the block. When a GET operation is done on the API : /transactions/{uuid}, the response contains a payload field which is hashed. What does this payload consist of? Is it the hash of the args sent when executing a chaincode function? How is this hash calculated? Is there any way to get the data from it?
harshal
2016-06-16 15:57
me and @pkulkark are trying to write a sample application where we are interested in tracking the historical changes for a particular value in a world state. Since apart from world state, older blocks don't keep the world state (but only hash of world state) we are kinda stuck there. All we want to do is plot the changes in the value against time while traversing the blocks. Also, we don't want to overload world state by keeping all the old data in world state itself. Any pointers?

But until that happens is there any way around with existing impl?
garisingh
2016-06-16 16:12
@harshal and @pkulkark - it kind of depends on exactly how complex your chaincode logic is. The actual payload of every transaction is stored within each transaction in a block (function invoked and parameters passed). Depending on what your actual chaincode functions do, it is possible to either "replay" the transactions outside the chaincode just by parsing each block / set of transactions or depending on the payload itself (e.g. you are actually passing the updated state in the invoke), you could use that. The other option would be to use the custom events (which I think are now committed) from within your chaincode to output the latest state at the end of a function invocation within chaincode. These events would be available via the event API or should be available waiting the transaction metadata in the recorded blocks
garisingh
2016-06-16 16:12
(not optimal / ideal) but could / should work
harshal
2016-06-16 16:32
@garisingh: thanks. The restful API endpoint *GET /transactions/{UUID}* returns only payload hash. I was trying to dig around code to see how this payload hash is calculated.
harshal
2016-06-16 16:36
I presume the payload is converted into a byte array and then a hash is calculated on that byte array.
garisingh
2016-06-16 16:42
should be base64 encoded actually
garisingh
2016-06-16 16:42
at least transactions are base64 encoded on the blocks endpoint
harshal

I found this in core.yaml:

# This is the basis for the Golang Dockerfile. Additional commands will
# be appended depedendent upon the chaincode specification.
Dockerfile: |
from hyperledger/fabric-baseimage
#from utxo:0.1.0
COPY src $GOPATH/src
WORKDIR $GOPATH
Does that mean we can add something to the baseimage for the docker container the go code is running in?
ghaskins

So would that be a possible way to have oracle-like behaviour? Or would that be considered bad practice..
arner

I mean, in theory you could maybe even run a light bitcoin node or connect to the ethereum network
ghaskins
2016-06-16 20:01
you mean to place some other task in that container as an ENTRYPOINT type process?
arner
2016-06-16 20:07
Yeah, something like that... Would be kind of a hack and I don't know how it would play with the on-demand nature of the vm. Maybe it'd be better not to run a fullblown process but still it opens up possibilities.. Can we use the http library to make calls outside of the vm
arner
2016-06-16 20:08
?
ghaskins
2016-06-16 20:18
right now? yes. Long term, no, that would be bad
ghaskins
2016-06-16 20:19
right now little is done to lock it down, but this needs to change
ghaskins
2016-06-16 20:19
the only thing chaincode should do is react to things coming from the peer, like invoke()/query() requests
ghaskins
2016-06-16 20:19
and those methods should be modeled on a pure function where the only persistence is the world-state
ghaskins
2016-06-16 20:20
if you reach outside the container, it will impact the determinism of your response
arner
2016-06-16 20:21
Right. That would be bad indeed. Is there any thought being put into how to handle the oracle problem? Or would it be less of an issue in a permissioned environment?
ghaskins
2016-06-16 20:23
Yes, system chaincode is part of that story

@garisingh @iamsamwood re: your discussion above about asset management example: it does not appear that the REST API alone can be used for this example given then need for certs in metadata, but running the [https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management/app] app does work
mikezaccardo

it requires a cluster of validating peers with security and privacy enabled (and probably something other than noops for consensus, but not totally sure if that’s required)

you can set this up using the compose blueprints that are located somewhere in the codebase (the link to it has since broken)

@vinding a while back you asked if it’s straightforward to set up (sorry for delay) — it is straightforward to set up using my blueprint, but developing it was tricky because i had trouble finding documentation for everything that was needed by it. it ended up being some trial end error wrt the environment variables passed to the containers.

hi all, i’ve expanded my deployment work to create clusters of VPs on different, geographically separated data centers, all of which report to one root node VP. i’ve found that the asset management example consistently fails on these distributed setups. containers for the chaincode are NOT deployed on the VP hosts. here’s a log of the app failing: https://gist.github.com/mikezaccardo/cb7112315dcedb0d242a37ea853f3ce6
mikezaccardo
2016-06-17 15:12
since these setups work when the VPs are all co-located, i’m thinking it may be some kind of timeout issue — is there a low timeout for chaincode deployment that may be failing here? i don’t see logs that confirm this, though.
mikezaccardo

I’ve been working on two enhancements on the side that I think will be useful at some point down the road beyond a basic robust fabric: 1) persistent events support by utilizing an external message queue, 2) asynchronous transaction API parallel to the /chaincode REST API. details are here including instructions to try out the prototype in the fork: https://github.com/jimthematrix/blockchain-features
jzhang

Hi there, I have a maybe naive question, I am just trying to understand the fabric spec right :
Do non-validating peers need to be certified by the CA to handle the API requests and event stream ?
The CA is used to allow the peers into the network, then who decides wether it's a peer (nvp) or a validator (vp) ?
thanks!

@sajz - good question - 2 part answer for now. First, we currently have a static whitelist for validating peers which you need to be added to (that list is in core.yaml and needs to be the same across all VPs) (I forget if we also set the total number somewhere as well). Second, in order to connect to the network as a validating peer, you need to have a role of validator which is assigned to you when you are registered with membership services (the ECA to be exact). If you have the role of validator, when you enroll (which happens under the covers when starting a peer), the certificate you are issued with have the role embedded in it as an attribute
garisingh
2016-06-17 19:32
Short answer: you need to be added to membership services with the role of validator and need to be added to the whitelist of validating peers in the config today
garisingh
2016-06-17 19:32
we'll be adding dynamic whitelist in the future as well
garisingh
2016-06-17 19:33
@kostas @simon @cca correct me if I said anything wrong ^^^^^
kostas
2016-06-17 20:17
right on the "you need to be added to memserv as a validator", right on the "we'll be adding dynamic whitelisting", wrong on the "static whitelisting". (we were about to add it, but we rightly ditched it in favor of a better, less hacky implementation that will make use of the event mechanism that was just added). as things stand right now, `vp2` can be taken offline, replaced with a different `vp2` and the system will admit them just fine. this is obviously not acceptable. (by the way, you set the number of expected VP nodes in `consenus/obcpbft/config.yaml`)
muralisr

@kostas: can you expand on the _ less hacky implementation that will make use of the event mechanism that was just added_ please ?

2016-06-18 17:09
@kostas - right - thanks - should have been more clear. but in the end, while you can have a different node connect as `vp2` if `vp2` goes down, that does mean that you would also have had to been able to enroll the second peer who wants to be `vp2` as well (since enrollPwd is one shot only). So if you have security enabled and you only ever issued enrollment credentials to 4 peers with validator role, no one else could actually join the network as `vp0,vp1,vp2 or vp3`

1) are you running all the peers in docker containers?
2) are you running in Vagrant?
3) if not running in Vagrant, you'll need to configure the docker daemon on your host system to listen on tcp (e.g. `-H ) instead of just the default unix socket
4) Are you using the Docker compose files in the *bddtests* folder?

buhrmi
2016-06-20 12:07
lol
ashnur
2016-06-20 12:07
buhrmi: i am not sure if you really want that
buhrmi
2016-06-20 12:07
i do
buhrmi
2016-06-20 12:07
i know what i want lol
ashnur
2016-06-20 12:08
however this correlates to something I was thinking about the other day
ashnur
2016-06-20 12:09
that if we had a right to the blockchain as we have right to freedom of speech, and this blockchain would be run by governments and firms and basically everyone in some aspect, it could simplify everything humans do and requires auditing
buhrmi
2016-06-20 12:09
@ashnur: yeah that's what i wanna build
buhrmi
2016-06-20 12:10
i thought that's hyperledger's vision
simon
2016-06-20 12:10
centralization is the bane of all systems
simon
2016-06-20 12:10
better come up with a structure like the internet
simon
2016-06-20 12:10
the network of networks
ashnur
2016-06-20 12:10
but the question as always is, what is the incentive to manage this for those who actually have the resources, and what are the guarantees that they will not steer it in a way that benefits them more than the common people
simon
2016-06-20 12:10
figure out a network of blockchains
buhrmi
2016-06-20 12:10
yeah well i think the fabric is a good starting point
simon
2016-06-20 12:10
i.e. a cross-chain transaction protocol
simon
2016-06-20 12:11
make it truly "hyper" ledger, like hypertext
buhrmi
2016-06-20 12:11
yup
buhrmi
2016-06-20 12:11
really would love a public test-chain
buhrmi
2016-06-20 12:12
maybe i can propose it
simon
2016-06-20 12:12
maybe you can host one
buhrmi
2016-06-20 12:12
on my phone
simon
2016-06-20 12:12

still very confused about the namespacing/permissions of the variables that are stored with `stub.PutState` in the chaincode examples
buhrmi
2016-06-20 14:16
are they global? what are they tied to? is there documentation about that?
simon
2016-06-20 14:18
buhrmi: the variables are per-chaincode
simon
2016-06-20 14:18
buhrmi: imagine one key/value table per chaincode
pschnap
2016-06-20 14:21
@buhrmi from what I recall there's a chaincode instance name and there are variable names within the chaincode for the state; the actual name the variables are stored under is chaincode_instance + internal_key so it can't be accessed by other chaincode instances, only the instance using it
buhrmi
2016-06-20 14:21
i see... can a chaincode be changed once it has been deployed?
ghaskins
2016-06-20 14:22
@buhrmi: right now, you can only upload a new one…eventually we will have “upgrade” as part of lifecycle management but it will be controlled
buhrmi
2016-06-20 14:25
@ghaskins: okay i was hoping the answer would be "no" cause i assume other users will interact with some deployed chaincode and it would be weird if behavor suddenly changes
ghaskins
2016-06-20 14:25
thats where the “controlled” comes in
ghaskins
2016-06-20 14:25
I think chaincode will need to have facilities that allow it to take part of when/whether it can be upgraded
ghaskins
2016-06-20 14:26
(which could include human/external approval)
ghaskins
2016-06-20 14:26
so, in this system, a chaincode would be written such that it disables upgrade as part of its policy should that be desired
ghaskins
2016-06-20 14:27
or, perhaps it requires 2-3 stakeholder approval, etc etc
buhrmi
2016-06-20 14:27
note that i'm thinking about a scenario where the blockchain is deployed publicly, inviting anyone to deploy chaincode
ghaskins
2016-06-20 14:28
shouldnt matter
ghaskins
2016-06-20 14:28
a blockchain is about governing change via rules that are agreed upon by consensus…you can make those rules whatever you want
buhrmi
2016-06-20 14:28
is there an example of one chaincode querying another chaincode?
ghaskins
2016-06-20 14:29
yes
buhrmi
2016-06-20 14:29
cool ...
buhrmi
2016-06-20 14:30
also, this `"secureContext": "user_type1_xxxxxxxxx"` in the rest api, is this ibm bluemix specific?
ghaskins
2016-06-20 14:31
first is raw/direct chaincode to chaincode invoke, second is chaintool based
buhrmi
2016-06-20 14:31
ok cool got it
ghaskins
2016-06-20 14:32
I dont think secureContext is bluemix specific
buhrmi
2016-06-20 14:36
hmmm to me it looks like the /registrar endpoint is tied to IBM bluemix credentials to authorize ...
muralisr
2016-06-20 14:36
@buhrmi
https://github.com/hyperledger/fabric/blob/master/examples/chaincode/go/chaincode_example05/chaincode_example05.go is another example (does not hardcode called chaincode’s ID)
ghaskins
2016-06-20 14:37
@buhrmi: I wouldnt be surprised if the membersrvc running on bluemix was integrated with bluemix credentials, but that doesn’t mean membersrvc in general is
ghaskins
2016-06-20 14:37
i thought you were asking about the secureContext field in general
buhrmi
2016-06-20 14:40
yeah i don't like this "secureContext" approach at all
buhrmi
2016-06-20 14:42
it has the word "secure" in it but i don't know how it's secure ^_^. the call is not signed or anything
buhrmi

bfuentes

ghaskins
2016-06-20 14:43
the problem is you are misunderstanding the architecture/intent there
ghaskins
2016-06-20 14:43
its not your fault, its confusing and poorly communicated, this hung me up too
ghaskins
2016-06-20 14:43
the issue is that you need to understand that part of that flow is intended to be part of the "client context"
ghaskins
2016-06-20 14:44
that is, if you look at a flow like this [client]->(rest)->[nvp]->(grpc)->[vp vp vp]
ghaskins
2016-06-20 14:45
its easy to assume that the (rest) portion is your client talking to the network
ghaskins
2016-06-20 14:45
and in that sense, the concept of “secureContext” is totally broken
ghaskins
2016-06-20 14:45
but the problem is, thats not the intended architecture
ghaskins
2016-06-20 14:46
rather, it looks like this: [trusted: [client]->(rest)->[nvp]]->(grpc)->[untrusted: [vp vp vp]]
ghaskins
2016-06-20 14:47
or, really, [trusted: [client]->(http)->[webtier]->(rest)->[nvp]] ….
ghaskins
2016-06-20 14:47
once you understand that, things start to make more sense
ghaskins
2016-06-20 14:47
also know that work is under way to collapse much of that via the SDK
ghaskins
2016-06-20 14:48
so, the “secureContext” is a mechanism that something like a trusted webtier and a trusted NVP convey identity via proxy
ghaskins
2016-06-20 14:48
for hosted wallets, etc
ghaskins
2016-06-20 14:49
if you wanted more of an SPV wallet type thing, you want to be using the SDK in which case the functions of client/nvp are collapsed together
ghaskins
2016-06-20 14:49
make sense?
buhrmi
2016-06-20 14:49
NVP VP SPV are abbreviations for....? ^_^
ghaskins
2016-06-20 14:50
VP= validating peer, NVP = non-validating peer, SPV is a bitcoin term, i think it stands for single payment verification
buhrmi
2016-06-20 14:50
ah okay , yeah then it makes sense
ghaskins
2016-06-20 14:51
i had the same thought as you: “how is this not completely broken”, heh
buhrmi
2016-06-20 14:51
haha
ghaskins
2016-06-20 14:51
understanding the above is key
ghaskins
2016-06-20 14:52
related, see the concept of a “registrar” in membersrvc parlance
buhrmi
2016-06-20 14:52
but still, i think it would be "cooler" to be able to deploy chaincode without having a user database and just use a "whatever-publickey" to "log in" and provide signatures
ghaskins
2016-06-20 14:52
im not sure what you mean
buhrmi
2016-06-20 14:53
i assume the membersrvc thing (i haven't looked into that very much) is looking up credentials to provide this "secureContext" value
ghaskins
2016-06-20 14:54
well, transactions on the actual network are signed by transaction-certificates which are subordinate to an enrollment certificate
ghaskins
2016-06-20 14:55
the membersrvc function is to manage/disseminate credentials and the issuance of certificates, of which secureContext plays a part
buhrmi
2016-06-20 14:55
yeah, so without having a transaction certificate signed by that enrollment certificate i can't send transactions, right?
ghaskins
2016-06-20 14:56
something like that, but that is on the (grpc) side of the link
buhrmi
2016-06-20 14:56
i want to deploy a node that does not use an enrollment certificate
ghaskins
2016-06-20 14:56
so, turn off security in your network
buhrmi
2016-06-20 14:56
and use self-signed everything
buhrmi
2016-06-20 14:56
will try
ghaskins
2016-06-20 14:57
or, turn on security but create an ACL for deploying chaincode that doesnt check tcerts
ghaskins
2016-06-20 14:57
or, do whatever you want
buhrmi
2016-06-20 14:57
haha
buhrmi
2016-06-20 14:57
sounds good :smile:
ghaskins
2016-06-20 14:57
all that matters is you have rules and all the nodes agree to them
buhrmi
2016-06-20 14:58
will experiment a bit
buhrmi
2016-06-20 14:58
i'm off to sleep
buhrmi
2016-06-20 14:58
thanks for the explanations
ghaskins
2016-06-20 14:59
the bottom line: your system decides what constitutes a valid transaction…if you want a system that doesnt require a tcert to be valid, then you code it that way
ghaskins
2016-06-20 14:59
(the funny thing being, thats the easy case ;)
ghaskins
2016-06-20 15:00
the hard case is when you actually do want them
buhrmi
2016-06-20 15:02
so i want a blockchain where i (or anyone else) can deploy chaincode without a certificate, while still being able to prove ownership over the deployed chaincode by having a private key and the chaincode is signed
buhrmi
2016-06-20 15:04
the attitude being "not giving a f*ck what's in the system, but if somebody tells me that he/she put it in there, he better be able to prove it"
simon
2016-06-20 16:38
yea good luck administrating that system
simon
2016-06-20 16:38
people will host warez servers in your chaincode
codascud
2016-06-20 18:16
@ghaskins: thanks for the explanation. really helpful.. In case of really, [trusted: [client]->(http)->[webtier]->(rest)->[nvp]] architecture. How (and why?) should one use the POST localhost:5000/registrar API?
ghaskins
2016-06-20 18:17
@codascud: I am not too familiar with that aspect of the system so I am not sure
codascud
2016-06-20 18:18
got it.. thanks…
ghaskins
2016-06-20 18:18
but I can say this: there is the concept of registrar in the SDK that is probably related
ghaskins
2016-06-20 18:18
and in that model, the registrar is responsible for proxy login of the things it is hosting
ghaskins
2016-06-20 18:19
so I suspect the /registrar endpoint is related to that
ghaskins
2016-06-20 18:20
e.g. if I am a wallet hoster…i might have X clients whom are integrated with some extrinsic identity system that the wallet hoster and wallet apps federate to
ghaskins
2016-06-20 18:20
one the hosting tier is happy with a security principal, it acts as a registrar for that principal w.r.t. the block chain
ghaskins
2016-06-20 18:21
IOW, the hosting tier, using registrar credentials, logs in the subordinate identity via proxy
codascud
2016-06-20 18:21
thanks.. Is CA different from registrar?
ghaskins
2016-06-20 18:22
i think so
ghaskins
2016-06-20 18:22
i think the registrar is a type of role in the identity system the CA manages
ghaskins
2016-06-20 18:22
i.e. one CA might have many registrars, each of which are responsible for some set of subordinate identities
garisingh
2016-06-20 18:23
@codascud: @ghaskins is fairly close in his explanation. Some of this is left over from previous ideas about non-validating peers (a concept which is more or less disappearing) as well as the lack of a native client for the fabric and membersrvcs APIs (the gRPC stuff - which the new Node SDK actually uses)
garisingh
2016-06-20 18:26
The various security endpoints exposed on the peer (/registrar, the get enrollment cert and get transaction cert) basically invoke a membersrvcs "client" code which is embedded in the peer code under the overs. So `/registrar` assumes that someone has already added users to the ECA (in the past via membersvcs.yaml , now also via the client SDK) and what it does is log in the user and download the enrollment material under the control of the peer (you can actually see all of the files in the `/var/production/.membersvcs` directory under something like clients
garisingh
2016-06-20 18:28
as @ghaskins says, this is then used a a pseudo *wallet* when using the transitional REST / JSON-RPC APIs (you include secureContext in the REST request and the peer hosting that endpoint checks to see if it has the enrollment material for that "user" in its file system) to create signed transactions which are then submitted to the blockchain
ghaskins
2016-06-20 18:29
@garisingh: that makes sense to me, thanks for clarifying
garisingh
2016-06-20 18:30
And the original concept was that the entity hosting the peer would put their own security (e.g. proxy, API mgmt) in front of the REST endpoint. This is still viable, although moving forward we have the new NodeJS SDK and I'd expect that we'll actually start building wallets / REST servers, etc on top of that and extracting this stuff out of the peer code itself
garisingh
2016-06-20 18:31
also, the new Node SDK gives full access to membersvcs directly rather than going through the peer. The plan is to also start building SDKs in other languages as well as extract the current Go client out of the peer as well for standalone use
garisingh
2016-06-20 18:31
OKAY - my essay is over now :wink:
codascud
2016-06-20 18:32
thanks @garisingh @ghaskins for the explanation!
ghaskins
2016-06-20 18:32
@garisingh: everything you said is consistent with my understanding (except I wasnt as familar with the legacy paths, like /registrar) so thank you for all that
garisingh
2016-06-20 18:34
no worries. we should probably offer up some deep dive sessions on membersvcs, the new SDK, etc to get folks up to speed on all of the changes, etc plus what all this stuff actually does / means. Its definitely not entirely obvious
ghaskins
2016-06-20 18:39
@ghaskins uploaded a file: https://hyperledgerproject.slack.com/files/ghaskins/F1JHTDZ97/pasted_image_at_2016_06_20_02_39_pm.png and commented: This is the picture I have in my head describing all this
ghaskins
2016-06-20 18:40
the concept of registrar/securityContext is to bridge those two domains
ghaskins
2016-06-20 18:40
the hosting tier lives in both domains
ghaskins
2016-06-20 18:44
@garisingh: accurate?
garisingh
2016-06-20 18:45
@ghaskins: looks good
ghaskins
2016-06-20 18:45
(and, as we both mentioned, is collapsed in the SDK model
garisingh
2016-06-20 18:45
did you have that picture or did you use one of your magic tools to whip it up real quick?
ghaskins
2016-06-20 18:45
i just whipped it up
ghaskins
2016-06-20 18:46
feel free to reuse
ghaskins
2016-06-20 18:47
i think what gets lost on people joining the project is that pretty much the entire rest-api is only meant to be used in that “trusted” box
ghaskins
2016-06-20 18:49
so, theres a documentation opportunity I suppose

Hello, I was wondering if someone could clarify the present state of Transaction Confidentiality. The protocol document has the section:
*4.7.2 Simplified transaction confidentiality* that states
>Disclaimer: The current version of transaction confidentiality is minimal, and will be used as an intermediate step to reach a design that allows for fine grain (invocation) access control enforcement in the next versions.
Is the _simplified transaction confidentiality_ model what is currently toggled in the core.yaml configuration file?

@simon: what's the alternative? using a CA?
buhrmi
2016-06-21 01:04
this entire exercise is to create something without a central authority ... so using a certificate authority goes against the core idea of an open block chain
adc
2016-06-21 07:13
@nick.dawson: what we have currently in the fabric is an hybrid between what is described in Section 4.7.2 and Section 4.3.2. In this hybrid, the symmetric chain key is replaced by an asymmetric key pair whose secret part is distributed to the validators at enrollment time. Therefore only validators can decrypt the transactions.

@all Is there an example on how to use ibm-blockchain-js v1.0.0? https://github.com/IBM-Blockchain/ibm-blockchain-js have snippets.. quite helpful.. but am wondering if someone have a sample project?
nick.dawson
2016-06-21 21:28
CC: @kostas
@adc: Thank you for the clarification. In this hybrid approach, is there a way to keep transactions confidential to a subset of the validating peers? For example, if I have three parties (Party A, Party B, and Party C) and all parties run validating peers, is there a way for Party A to transact with Party B without Party C being able to see the content of the transaction?
As I understand it, in the hybrid approach, validators can decrypt all of the transactions, so Party A and Party B would not be able to initiate transactions without party C being able to decrypt them. The transactions in this case would be hidden from Users that are transacting through NVP, but the VP would have full visibility into the transactions.
Is this correct?

Hey everybody, quick question. I am using Postman to communicate with the chaincode which works perfectly. The issue I just ran into and been trying to figure out is when I attempt to send an object in the args instead of multiple strings, such as in the cp chaincode example, I get this error: "data": "Error unmarshalling chaincode request payload: json: cannot unmarshal object into Go value of type string"
simon
2016-06-22 15:32
i don't think you are allowed to send an object?
castlesb
2016-06-22 15:35
For instance, "args":[
{"name":"test name", "address":"test address"}
]
castlesb
2016-06-22 15:36
instead of "args":[
"test name", "test address"
]
simon
2016-06-22 15:36
yes, i don't think that's supported
castlesb
2016-06-22 15:37
Gotcha, thanks for the response!

I've seen the term "sub-chain" used in some parts of fabric documentation. Could someone give me some pointers on how does that actually work? Where can I read detailed info on subchains? How do multiple chains interact in a single hyperledger fabric network?

Can I get the value of the state from NewChaincodeQuery() function?

I have successfully brought up the system on a Ubuntu 16.04 desktop and a Mac OSX laptop. By success I mean I can deploy the example02 chaincode and run invoke transactions and queries against the running docker vms. However when I deploy the system on a ubuntu laptop I can not successfully run the "make peer" command in vagrant. The error I get is: Sending build context to Docker daemon 16.97 MB

@tim.s: can you try to do ]$ make peer from inside the fabric folder?
tim.s
2016-06-22 20:04
That is where I was $GOPATH/src/github.com/hyperledger/fabric when I was running the 'make peer'
ghaskins
2016-06-22 20:06
@tim.s: so IIUC you are trying to build outside of vagrant?
ghaskins
2016-06-22 20:07
oh wait, you said “in vagrant"
ghaskins
2016-06-22 20:07
nm
tim.s
2016-06-22 20:08
I noticed that in install.md it has the 'make peer' but in dev-setup.md it has 'make peer-image'
ghaskins
2016-06-22 20:09
they are different commands
ghaskins
2016-06-22 20:10
“make peer” builds the peer executable, peer-image builds the docker container that is intended to host a peer executable
tim.s
2016-06-22 20:10
yes - I got onto this path because in the ../fabric/build/bin there was no peer command
tim.s
2016-06-22 20:10
also I could not make membersrvc
ghaskins
2016-06-22 20:10
yes, “make peer” should generate ../fabric/build/bin/peer binary
ghaskins
2016-06-22 20:11
as a somewhat blind guess, i am wondering if you are having problems with the hostfs
ghaskins
2016-06-22 20:11
if you are in vagrant, the environment is largely normalized…but one thing that isnt is certain parts of the filesystem are punched through to your host
ghaskins
2016-06-22 20:12
(and this includes the $GOPATH)
ghaskins
2016-06-22 20:12
so, perhaps we are seeing some kind of problem with accessing the shared filesystem to ubuntu
tim.s
2016-06-22 20:12
that is a possibility. the laptop I am trying to do this on is a client laptop reprovisioned for ubuntu with only 58GB of disk. The others I successfully brought up are my own
codascud
2016-06-22 20:12
ah..
ghaskins
2016-06-22 20:12
i assume you have space at least
codascud
2016-06-22 20:13
do you have virtualization enabled?
codascud
2016-06-22 20:13
in your bios?
ghaskins
2016-06-22 20:13
(can you post the result of “df -a"
ghaskins
2016-06-22 20:13
@codascud: @tim.s wouldnt be able to vagrant up if he didnt
tim.s
2016-06-22 20:13
yes - df -h says I still have 52GB
ghaskins
2016-06-22 20:13
@tim.s ok
ghaskins
2016-06-22 20:14
@tim.s if you are willing to experiment
ghaskins
2016-06-22 20:14
can you try something for me
ghaskins
2016-06-22 20:14
?
tim.s
2016-06-22 20:14
be happy to - otherwise I am thinking of completely rebuilding the entire box
ghaskins
2016-06-22 20:15
if you look in df, there are 4 places that the vagrant image punches through to the host (/vagrant /local-dev /hyperledger and the $GOPATH)
ghaskins
2016-06-22 20:15
we want to see if we can build something that is NOT in one of those
tim.s
2016-06-22 20:16
ok
ghaskins
2016-06-22 20:16
i think /tmp qualifies, so lets do this there
ghaskins
2016-06-22 20:16
mkdir /tmp/go; export $GOPATH=/tmp/go
nkunkel
2016-06-22 20:16
Is there a docker image for Hyperledger and it's dependencies for s390 RHEL 7.1?
ghaskins
2016-06-22 20:17
cd /tmp/go/src/github.com/hyperledger/fabric; make peer
ghaskins
2016-06-22 20:17
@nkunkel: i dont think prefabricated, but the base image for s390 RHEL $something is available and you can build the rest on it
ghaskins
2016-06-22 20:18
the only thing I am not sure on is the version of RHEL
ghaskins
2016-06-22 20:18
@vpaprots would know
tim.s
2016-06-22 20:18
can I find that with docker images?
ghaskins
2016-06-22 20:18
@tim.s find what? the s390 stuff?
tim.s
2016-06-22 20:19
yes

nkunkel

Nope, just trying to get set up. Been on a really old version of OBC for forever and thought this might be a good opportunity to switch to fabric.
nkunkel
2016-06-22 20:21
Maybe the 7.2 image works on 7.1?
vpaprots
2016-06-22 20:21
I would think it shouldnt be all that different

2016-06-22 20:24
@ghaskins: So I must have missed a step
vpaprots
2016-06-22 20:24
on 390, you got to install docker yourself.. and it doesnt come part of the repo yet, unless you are on xenial
tim.s
2016-06-22 20:25
The laptop is 16.04
nkunkel
2016-06-22 20:26
yup I've seen that, already got docker installed
nkunkel
2016-06-22 20:27
Whats the link to the 7.2 Hyperledger docker image?
vpaprots
2016-06-22 20:27
try running `make behave`.. that should pull everything auto-magically
nkunkel
2016-06-22 20:28
dope, I'll try that
tim.s
2016-06-22 20:34
still get the same error
nkunkel
2016-06-22 22:31
yea running make clean peer at the end of the setupRHELonZ.sh script gives me "No Go in Path". Looks like it didn't install golang correctly

@ashnur: Apart from the documentation on fabric… you can try Bluemix (it has a free account for 30 days)
ashnur
2016-06-23 14:35
I am looking at the docs
ashnur
2016-06-23 14:36
and I am confused
codascud
2016-06-23 14:37
looking for installation instructions or general information about fabric?
ashnur
2016-06-23 14:37
Ok, so more specifically, I would like to try to run an instance and try to write some chaincode and run it to see what it is possible with it
ashnur
2016-06-23 14:37
like do some POC or something
ashnur
2016-06-23 14:38
(i am not very specific, i just realized:( )
codascud
2016-06-23 14:40
well you can try chain code using Bluemix and follow instructions here https://github.com/IBM-Blockchain/learn-chaincode...
codascud
2016-06-23 14:41
https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go has great examples too...
ashnur
2016-06-23 14:42
sadly, I do have to run an own node and not use some third party service
ashnur
2016-06-23 14:42
however I think it is enough to just run a non-validating node
ashnur
2016-06-23 14:43
the problem for me right now is the sheer amount of docs. I just don't know where to look, there are too many places to look at. :smile:
codascud
2016-06-23 14:44
yeah you are right.. so if you want to do the installation then either (1) install using vagrant OR (2) install everything from scratch...
codascud
2016-06-23 14:44
ashnur
2016-06-23 14:44
codascud
2016-06-23 14:44
(2) follow steps in https://github.com/hyperledger/fabric/blob/master/devenv/setup.sh
ashnur
2016-06-23 14:45
ok, so the dev-setup is not just for fabric-devs?
codascud
2016-06-23 14:45
I am not sure of that...
ashnur
2016-06-23 14:45

2016-06-23 14:45
ok, thanks for the pointers :slightly_smiling_face:
ghaskins
2016-06-23 14:46
@ashnur: if you want to do any dev, including chaincode, the devenv is a good way to start
ghaskins
2016-06-23 14:46
but that is good feedback for the doc, we should make that more clear
ghaskins
2016-06-23 14:47
in its simplest form, you just need a system with virtualbox+vagrant, check out the tree, cd to devenv, and do “vagrant up"
ashnur
2016-06-23 14:47
ghaskins: I think it would be nice to just have a list of links on the beginning of the project readme: if you want just this: read that, if you want to develop this, read that.. etc
ashnur
2016-06-23 14:47
i know vagrant at least :smile:
ashnur
2016-06-23 14:48
(and i hate it too, but i think all devops tools are terrible)
ghaskins
2016-06-23 14:48
(theres a small amount of peripheral requirement too, like for instance you need an os/bios with HVM/VMX enabled to run the virtualbox-based vagrant
ashnur
2016-06-23 14:48
yeah, i know :smile:
ghaskins
2016-06-23 14:48
but, if you manage to get vagrant up to complete without errors, then “vagrant ssh” and you should have everything you need to run fabric and develop chaincode
ashnur
2016-06-23 14:49
thank you, that is encouraging :smile:
ghaskins
2016-06-23 14:49
heh, sorry, i didnt mean to emphasis the “if you manage"
ghaskins
2016-06-23 14:49
its pretty reliable
ashnur
2016-06-23 14:49
i set up vagrant more than a dozen different times for different purposes before, but never ever without seriously annoying issues :slightly_smiling_face:
ashnur
2016-06-23 14:50
yeah, after it is configured, it usually just runs fine, that is nice
ghaskins
2016-06-23 14:50
the biggest problem we seem to run into is people within China sometimes cannot access some of the docker repositories that the vagrant provisioner tries to access
ashnur
2016-06-23 15:03
I am from europe so probably will not be an issue :slightly_smiling_face:

In the REST call what does the “id” mean?
{
"jsonrpc": "2.0",
"method": "query",
"params": {
"type": 1,
"chaincodeID":{
"name": <address>
},
"ctorMsg": {
"function":"query",
"args":["a"]
}
},
"id": 5 ---> What is id here?
}
sheehan
2016-06-23 20:38
"The request id. This can be of any type. It is used to match the response with the request that it is replying to."
codascud
2016-06-23 20:40
So does this mean that if two request is sent to server with id as “5" then there will be an error?
sheehan
2016-06-23 20:42
no, you can use the same ID for every request if you want
codascud
2016-06-23 20:43
hmmm…thanks @sheehan
sheehan
2016-06-23 20:48
One reason you may use it is for batch requests http://www.jsonrpc.org/specification#batch but I’m not sure if the Fabric JSON-RPC API supports batching
sheehan
2016-06-23 20:49
@anya: Are batch requests supported by the JSON RPC API? ^^^

What is the next step to set up my dev environment for running fabric? I just used this script (https://github.com/hyperledger/fabric/blob/master/devenv/setupRHELonZ.sh)
Do I now just need to make a bash script to start a validating peer node and I'm done?
codascud
2016-06-24 02:29
@nkunkel: have you compiled peer?
codascud
2016-06-24 02:30
if you are installing fabric without vagrant then go to fabric/ folder and type in make peer
codascud
2016-06-24 02:30
if oyu need CA, then also do a make membersrv
codascud
2016-06-24 02:32
and if you need REST enabled, then go to core/rest]$ and start http server with this command: sudo http-server -a 0.0.0.0 -p 5554 --cors
nkunkel
2016-06-24 02:34
Is there a scenario where one would not need REST enabled. How else is the chaincode invoked or queried?
codascud
2016-06-24 02:34
yes.. you can use CLI to do all chaincode operations..
codascud
2016-06-24 02:35
REST is optional...
nkunkel
2016-06-24 02:36
Interesting, thank you (fabric newbie)
codascud
2016-06-24 02:37
sure… do execute the test cases after you compile peer… can be done by ]$ make unit-test …
nkunkel
2016-06-24 03:10
so after starting the peer, and enabling rest I just deploy the chaincode and I'm good to go?

So I guess I should be trying out the dev-preview then
cbf
2016-06-24 08:10
yes, please :grinning:
ashnur
2016-06-24 09:22
well, setting up vagrant went surprisingly smooth
ashnur
2016-06-24 09:22
i mean, i am inside the running box now, after vagrant ssh :slightly_smiling_face:
ashnur
2016-06-24 10:16
i spoke too soon. :disappointed:
ashnur
2016-06-24 11:07
I remember seeing some kind of mentions of public meetings here?
codascud
2016-06-24 12:25
@nkunkel: yes… Then if you want, you can configure some options available in core.yaml file
codascud
2016-06-24 14:58
Any idea How are the users defined in membersrv/membersrvc.yaml replicated to all the peers in the network?
garisingh
2016-06-24 15:54
@codascud: users are not replicated. Authentication / authorization of users at the peer level is handled via digital signatures. Peers initially connect to membership services and download their relevant enrollment material (their certificates, encryption keys and root certificate for the ECA/TCA). Client / users would also initially connect to membership services and get their enrollment material as well. They then use their enrollment key to receive transaction certificates which they use to sign transactions and submit to peers
garisingh
2016-06-24 15:55
Now perhaps you were talking about what happens when using the REST interface and the story there is a bit different because in that case the peer which you initially "log on" to via the /registrar endpoint effectively becomes the "client" for you and has your enrollment material which means that you can only invoke transactions via REST on that peer with any single ID
garisingh
2016-06-24 15:57
https://github.com/hyperledger/fabric/blob/master/sdk/node/README.md does a pretty good job of showing how this works using the new NodeJS SDK which uses the native gRPC API directly rather than using the REST endpoints
codascud

garisingh
2016-06-27 09:07
@nick.dawson: that error generally occurs if the user does not exist in membership services or potentially you were using an older version of membership services at some point and it is pointing at a database with an older structure.

Hi @cbf, the images don’t have any description, source repository reference, etc. It will really help for this purpose

Call to /registrar gives the following error:
{
"Error": "rpc error: code = 2 desc = 'Identity lookup error: sql: no rows in result set'"
}
Payload:
{
"enrollId": "broker",
"enrollSecret": "password"
}
How do I create a new client named broker? Do I have to edit membersrvc.yaml file? Thanks..

How can I add mode users with registrar role? I have a network of 3 peers and one CA
cbf
2016-06-27 23:06
@codascud: membersrvc is not my area of expertise… sorry… @garisingh more likely has insights for that
codascud
2016-06-27 23:07
thanks for the reply! Will keep trying...
garisingh
2016-06-27 23:09
The /registrar endpoint is actually used for logging in existing users. Simplest option is to add the user in the membersrvc.yaml file
codascud
2016-06-27 23:09
Got a dummy registrar working.. Had to add the (1) user in membersrvc.yaml and ALSO under (2) attributes:
# attribute-entry-0: diego;institution_a;company;ACompany;2015-01-01T00:00:00-03:00;;
attribute-entry-0: broker;institution_a;company;ACompany;2015-01-01T00:00:00-03:00;;
codascud
2016-06-27 23:10
Is that the correct way @garisingh ?
garisingh
2016-06-27 23:10
Assuming you are on the latest version of the fabric, you can now also use the NodeJS SDK to create new users rather than adding them directly to the YAML file
codascud
2016-06-27 23:11
got it… have not tried the SDK yet.. will do it soon.. Thanks @garisingh @cbf!!
codascud
2016-06-27 23:12
Initially I was just adding user under the “Users:” tag… seems like we also need to write it under “attributes” secion aswell...
garisingh
2016-06-27 23:13
I will need to doublecheck on that but if that works for you now it does not hurt anything
codascud
2016-06-27 23:13
yup true :-}
codascud
2016-06-28 00:04
There seems to be a bug (or may be i am getting it wrong):
codascud
2016-06-28 00:04
Once I call /registrar API and successfully register a user
Req: { "enrollId": "jim", "enrollSecret": "6avZQLwcUe9b" }
Res: { "OK": "User buyside is already logged in." }
Then the second time the API return OK even with WRONG password:-
Req: { "enrollId": "jim", "enrollSecret": "wrong Password" }
Res: { "OK": "User buyside is already logged in." }
codascud
2016-06-28 00:05
is it expected?
garisingh
2016-06-28 00:50
Sadly yes
garisingh
2016-06-28 00:51
You only need to and can log in once
garisingh
2016-06-28 00:53
After that, when you issue invoke calls you will put the enroIlID in the secureContext field and behind the scenes the peer acts like a wallet for you
codascud

trying out fabric, and I started the first validating node with noops and without security enabled. then i deploy the 02 example from a different ssh prompt, seems to work fine, the validating (in its name at least) node outputs: `08:54:09.091 [container] WriteGopathSrc -> INFO 018 rootDirectory = /opt/gopath/src` (and nothing else). Then I write `peer node status` in the same prompt from where I deployed the example, and it outputs : https://gist.githubusercontent.com/ashnur/777f6256f71b9290df9debd178897cba/raw/219042dc0096723b600f2f47838cc27a196f3dd1/peernodestatus

I suspect I got lost somewhere, but I don't know why it says connection refused
garisingh

@ashnur - are you running the peer node in a Docker container?
ashnur
2016-06-28 13:06
@garisingh: i am running the dev env
garisingh
2016-06-28 13:06
in Vagrant? (sorry - been a while since I looked at those docs - I run everything native)
garisingh
2016-06-28 13:07
try setting the environment variable CORE_PEER_ADDRESSAUTODETECT=true
ashnur
2016-06-28 13:07
yes, windows 10 host, virtualbox & vagrant on an ubuntu box on which Docker is running
ashnur
2016-06-28 13:08
will try but since then i tried out bunch of other stuff not sure if i can still reproduce it exactly
garisingh
2016-06-28 13:09
else the peer reads the value out of core.yaml (and the default value is 0.0.0.0:30303 in the core.yaml)
codascud
2016-06-28 13:25
Where does the “fmt.Println()” statements written in CC get printed by default? I have peer running in debug mode but still don`t see the fmt.Println() stmts.. CC works fine… I can get and put values from CLI...
simon
2016-06-28 13:27
they should go to stdout
codascud
2016-06-28 13:27
stdout of peer?
simon
2016-06-28 13:28
no, of chaincode
ghaskins
2016-06-28 13:29
I think (unless something has changed) that if you do a standard deployment, the cc stdout is not externally accessible
codascud
2016-06-28 13:30
hmmmm… so I have peer & membersrvc running.. I dont see o/p on them.. Where is the chaincode stdout?
ghaskins
2016-06-28 13:30
if you use devmode, it just hits the terminal in which you launched the cc in devmode
codascud
2016-06-28 13:31
ah..got it..thanks… And is there a CC log configuration?
ghaskins
2016-06-28 13:31
not sure, there needs to be if there isnt one
ghaskins
2016-06-28 13:32
its not been a painpoint for me because I am still in the phase of exclusively using devmode
ghaskins
2016-06-28 13:32
I would search the issues, and, if none found, create one
ghaskins
2016-06-28 13:33
I would like to see that feature too, at least for dev
garisingh
2016-06-28 13:35

2016-06-28 13:35
yeah.. looking into it

@garisingh: didn't change much and I have to finish something before I can get back to that issue :slightly_smiling_face: but thanks and I will follow up after I am done
codascud

@garisingh: the dev mode is enabled in core.yaml (mode:dev), am I correct?
muralisr
2016-06-28 13:43
@codascud: I’d use ./peer node start —peer-chaincodedev mode which does all the right things for dev mode

including set chaincode.mode to dev

so, this marbles demo is really nice and all, but i am already seeing cracks :slightly_smiling_face:

2016-06-28 14:38
@ashnur status just reports “up” currently.

any idea what could be going wrong here?
muralisr
2016-06-28 14:46

can you paste the chaincode startup command , peer start up command and the query command please
muralisr
2016-06-28 14:47
CORE_CHAINCODE_ID_NAME=mycc
muralisr
2016-06-28 14:47
then “-n mycc” should be used in the query

codascud

yes
muralisr
2016-06-28 15:01
can you paste the chaincode command ?
codascud
2016-06-28 15:02
hmmm.. the CLI command?
muralisr
2016-06-28 15:03
so in dev mode, the user runs the chaincode
muralisr
2016-06-28 15:03
as opposed to the peer “starting” it
codascud
2016-06-28 15:07
ohk.. there seems to be an issue with the handle (contract address?) Can you help me with the CLI command that I can execute to run the query->read() in cc

and then invoke, query etc

ah! it workes!! thanks!!! @muralisr
muralisr
2016-06-28 15:26
anytime, @codascud
jzhang
2016-06-28 15:30
@muralisr: do I understand it right that chaincode has to be either available in the peer’s local file system or https://github.com? I’ve tried both and both worked fine, but the same chaincode pushed to an enterprise github within my company’s firewall (with an url like https://github.ibm.com) I could not get it to deploy successfully
ghaskins
2016-06-28 15:37
jzhang: one thing to understand is that a ton of the system was designed with the assumption that an NVP is part of “the client”….so the right way to think about it is the it has to be available to the _clients_ local filesystem, not necessarily “a peer” per se
ghaskins
2016-06-28 15:37
this becomes more apparent when you use the SDK, which collapses “the client” + NVP into one process
jzhang
2016-06-28 15:37
fair point Greg, for my specific case I’m using REST APIs to deploy
ghaskins
2016-06-28 15:38
this process then packages up the chaincode for a peer-digestable transaction and is carried around in payload
ghaskins
2016-06-28 15:38
yeah, the REST api is really a way for a client to extend into the NVP
ghaskins
2016-06-28 15:38
once I understood that point, things made a lot more sense
ghaskins
2016-06-28 15:39
things feel more natural (to me) when using the SDK
jzhang
2016-06-28 15:40
thing is though, REST APIs are the easiest way to deploy chaincode during development
ghaskins
2016-06-28 15:40
understood, and theres nothing wrong with continuing to do that (at least while the REST api is not deprecated)
ghaskins
2016-06-28 15:41
just understanding that the thing you are talking to is considered part of your client makes it easier to understand what is happening
jzhang
2016-06-28 15:41
i haven’t tried the SDK, does it work headlessly? or would i have to write a wrapper node app to use it?
jzhang
2016-06-28 15:41
yes Greg, that’s a very good point
ghaskins
2016-06-28 15:41
im not sure what you mean “headlessly”….its a nodejs based SDK so presumably you would need a nodejs application to drive it
ghaskins
2016-06-28 15:42
but, it doesnt require an NVP, so in that sense its “backendless” at least, heh
jzhang
2016-06-28 15:42
(my next question was going to be when would the REST API start supporting a zip upload, but now with what you said above it’s a moot point)
ghaskins
2016-06-28 15:42
yeah, the “zip upload” is what comes out the other side (of the NVP and/or SDK)
ghaskins
2016-06-28 15:43
the payload is not signed, is not a deploy txn, etc, until it hits that processing layer
ghaskins
2016-06-28 15:43
it “feels” like it is because of the way the REST api presents it, but its not fully baked
jzhang
2016-06-28 15:43
i know there’s a node package that i can use with require() in my node wrapper, i know how to do that. I was wondering if there’s a headless package that I can use to something like “node sdk.js —file-upload —file /some/path/to/chaincode"
jzhang
2016-06-28 15:44
sounds like the answer is no
jzhang
2016-06-28 15:44
but it would be a useful tool to have during chaincode development
ghaskins
2016-06-28 15:44
oh i see, i think the answer is no but I also think that wouldnt be hard to come up with
jzhang
2016-06-28 15:44
yep
ghaskins
2016-06-28 15:44
I have been thinking about similar for chaintool clients
ghaskins
2016-06-28 15:44
which are a superset of that
codascud
2016-06-28 15:47
May be this one pointing to your network:
codascud
2016-06-28 15:47
@jzhang:
jzhang
2016-06-28 15:53
thanks for the pointer @codascud , looks interesting, although it still doesn’t help in my case since it still requires the code to be pushed to a http://github.com repo (a requirement per the Bluemix-based blockchain service).
jzhang
2016-06-28 15:54
to me if i need to keep my chaincode private it looks like I’d have to resort to using the SDK
ghaskins
2016-06-28 15:55
(or at least understand you need a privately controlled NVP ;)
ghaskins
2016-06-28 15:55
though I think the SDK is the way to go
jzhang
2016-06-28 15:58
is there doc on setting up a NVP? I’ve heard on and off that NVPs are to be removed from the architecture, and also does the v2.0 architecture still have an NVP equivalent?
jzhang
2016-06-28 15:59
note that the NVP would have to be a native process (as opposed to a docker instance) since the chain code is constantly changing during development
ghaskins
2016-06-28 16:33
yes to doc, and yes, I think they might be going away, or at least away in this particular capacity
ghaskins
2016-06-28 16:33
also note that docker vs native process shouldnt matter much, architecturally
ghaskins
2016-06-28 16:34
you could always launch the NVP with a volume mount if for some reason it made sense to your workflow to have an NVP in a container
ghaskins
2016-06-28 16:34
that said, it probably doesnt
jzhang
2016-06-28 16:39
scratch what I said above re: native process, you are right i could mount a volume when launching the container to point to the chaincode folder

I am getting an error on “go build ./“ while creating my function that gets called by Query(),.. The error is: Error: t.myReadFn undefined (type *SimpleChaincode has no field or method myReadFn)
Any pointers how to fix it?
garisingh
2016-06-28 17:17
@codascud: would have to look at your actual chaincode. Likely you can fix the error by just removing the `t.` from `t.myReadFn` or making sure that `myReadFn` is attached to the SimpleChaincode struct
tim.s
2016-06-29 13:07
fmt.Printf within chaincode question. When I deploy and invoke chaincode to several peers the fmt statements do not generate any output to the terminal screens. As a test I was deploying example02 which contans fmt statements. Is there a way of getting the output of the fmt methods?
codascud
2016-06-29 13:20
@tim.s: I was facing the same issue yesterday.. Here is how you can see the print statements…
codascud
2016-06-29 13:21
(1) build your code by myCCdir]$ go build ./

(2) CORE_CHAINCODE_ID_NAME=<any handle> CORE_PEER_ADDRESS=127.0.0.1:30303 ./myCCdir
codascud
2016-06-29 13:22
you can now see all your printf statemets on this soncole..

*console

2016-06-29 13:22
thanks - will let you know
tim.s
2016-06-29 13:26
@codascud: First problem encountered is that the build does not pull in http://github.com/op/go-logging - so I get build errors. Sorry I am a newbie with golang
codascud
2016-06-29 13:48
@tim.s: you can use a very simple example in the begining and build from that. Here is a very simple example:
codascud
2016-06-29 13:50
start/chaincode_start.go — I would suggest (I did it this way myself) compile this CC and add print statements to see o/p on console.. then move to finished/chaincode_finished.go….
tim.s
2016-06-29 16:54
@codascud: Thanks. I was able to get stdout printf to the console when I started a single peer using the sandboxsetup.md instructions. However
tim.s
2016-06-29 16:56
when I use the peer startup from the devnet-setup.md I do not get the stdout.
tim.s
2016-06-29 16:57
The difference is that using devnet-setup.md lets you start multiple connected peers whereas the sandbox-setup.md peer startup only allows a single peer node. At least I have not been able to connect a second one.
nkunkel
2016-06-29 21:06
I have a question involving chaincode functions. I know the standard Init, Invoke, and Query can be called by doing something like peer chaincode invoke -p ...... or peer chaincode query -p....
nkunkel
2016-06-29 21:07
What about other functions you defined. Like say I had a function approve.
yanglei
2016-06-29 21:07

nkunkel
2016-06-29 21:07
Would I have a chaincode approve -p...
nkunkel
2016-06-29 21:08
or would it just stay as invoke, and just the Function parameter I pass to -c be approve?
muralisr
2016-06-29 21:09
@nkunkel the later
nkunkel
2016-06-29 21:10
Okay that's what I thought, thank you
muralisr
2016-06-29 21:10
sure thing
nkunkel
2016-06-29 22:17
Having an issue, and wondering if it's a bug in fabric, or something I'm doing wrong on my end.
In my chaincode, apart from the standard Init, Invoke, and Query functions I have a few extra ones I have put in, for example one called Approve.
I can invoke my Init/Invoke/Query using peer chaincode deploy/invoke/query -p $CPATH -n $NAME -c '{"Function":"Init/Invoke/Query", "Args": ["egg"]}'
nkunkel
2016-06-29 22:18
Now if I want to trigger my approve function I do:
peer chaincode invoke -p $CPATH -n $NAME -c '{"Function":"Approve", "Args": ["egg"]}'
However that doesn't work. It doesn't call my Approve function, it calls my Invoke function.
tim.s
2016-06-30 00:27
@nkunkel: Look at the AssetManagement chaincode in the examples. It shows how to manage the addition function invocations from the Invoke function
nkunkel
2016-06-30 00:31
Oh wow, okay so the invoke just becomes a handler for all function calls that arent init or query?
ghaskins
2016-06-30 00:47
@nkunkel: FWIW, the chaintool project provides what you are looking for to a degree by managing the dispatch table for you

@codascud: Can you clarify the method you were describing to display printf statements in the console?
CORE_CHAINCODE_ID_NAME=<any handle> CORE_PEER_ADDRESS=127.0.0.1:30303 ./myCCdir
Does this mean I preface my chaincode deploys with CORE_CHAINCODE_ID_NAME=myhandle or does it have to be each individual invoke and query as well in order to see their corresponding printf statements?
So for example would this be correct?
CORE_CHAINCODE_ID_NAME=chaincode CORE_PEER_ADDRESS=0.0.0.0:30303 peer chaincode deploy -p http://github.com/hyperledger/fabric/chaincode/bank -c '{"function":"Init", "args":["name":"owner1", "balance":"1000"]}'

I am trying to set up a network of 4VP , 1NVP using dockers and a CA as an executable with security is enabled and privacy is disabled..I noticed that after I deploy the chaincode and call invoke functions I could retrieve the block height and transactions front the VPs, but in case of NVP it says no blockchain found...isn't the NVP also holds the copy of the shared ledger?

I am testing out the hyperledger/fabric-peer and hyperledger/fabric-membersrvc docker containers and when i try and deploy chaincode, the transaction results are:
```
"transactionResults": [
{
"error": "Error starting container: cannot connect to Docker endpoint",
"errorCode": 1,
"uuid": "2bc507ae-5adf-4ac7-ba9f-abc367ce6887"
}
]
```
This stack overflow article recommended mounting the docker socket into the docker container…
http://stackoverflow.com/questions/37573410/failed-to-launch-chaincode-specerror-starting-container-cannot-connect-to-dock
I tried mounting `-v /var/run/docker.sock:/var/run/docker.sock ` and it didnt resolve the issue.
this is my docker-compose files:
*compose-defaults.yml*
```
vp:
image: hyperledger/fabric-peer
environment:
- CORE_PEER_ADDRESSAUTODETECT=true
- CORE_VM_ENDPOINT=http://127.0.0.1:2375
- CORE_LOGGING_LEVEL=DEBUG
# Startup of peer must be delayed to allow membersrvc to come up first
command: sh -c "sleep 5; peer node start"
#command: peer node start
# Use these options if coverage desired for peers
#image: hyperledger/fabric-peer-coverage
#command: ./peer.test --test.coverprofile=coverage.cov node start
membersrvc:
image: hyperledger/fabric-membersrvc
command: membersrvc
```
*docker-compose.yml*
```
vp0:
extends:
file: compose-defaults.yml
service: vp
ports:
- "5000:5000"
- "30303:30303"
environment:
- CORE_PEER_ID=vp0
volumes:
- /var/run/docker.sock:/var/run/docker.sock
membersrvc:
extends:
file: compose-defaults.yml
service: membersrvc
ports:
- "50051:50051"
environment:
- CORE_LOGGING_LEVEL=DEBUG
```
*Not sure if I am missing something, but as i understand it, the VPs run the chaincode in docker containers. I am running a VP as a docker container (vp0). Is vp0 trying to spawn its own docker container to execute the chaincode?*
tuand
2016-07-01 17:33
the peer does run the chaincode inside a docker container. For docker-compose config examples, take a look at the files in hyperledger/fabric/bddtests
nick.dawson
2016-07-01 17:34
so it is running a docker container inside of a docker container?
tuand
2016-07-01 17:35
yes

2016-07-01 17:35
do an `ip ad` and see what docker0 is set to ? you might need to change your core_vm_endpoint

Instead of the "Error starting container: cannot connect to Docker endpoint”, I now get the following error:
```
{"transactionResults": [
{
"error": "Error starting container: Tag latest not found in repository http://docker.io/hyperledger/fabric-baseimage",
"errorCode": 1,
"uuid": "9333f022-e2f5-42da-b42c-088e420749d5"
}
]
}
```
To try and fix this i built the base image and tagged it as latest
```
$ cd $FABRIC/images/base && make docker
> ...
> Successfully built 7d600d503e09
$ docker tag 7d600d503e09 hyperledger/fabric-baseimage:latest
$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
hyperledger/fabric-baseimage latest 7d600d503e09 19 minutes ago 1.061 GB
hyperledger/fabric-baseimage x86_64-0.0.10 7d600d503e09 19 minutes ago 1.061 GB
```
It doesnt give me that error anymore, Now i get this error...
```
{"transactionResults": [
{
"error": "Error starting container: cannot normalise nothing",
"errorCode": 1,
"uuid": "a2253f1e-ffbe-4bb1-8f8c-d4c001cef572"
}
]
}
```
Any ideas on what could be going on? Did tagging it myself actually _fix_ anything or is there something else going on?
*update*: looks like the “cannot normalise nothing” error might be a docker for mac bug. googling “cannot normalise nothing” only comes up with one result:

Is it possible for a given VP to have the data within its premises(only to that VP), but not to other VPs? I am visioning like each VP has some data(not everything) to itself, not sharing with other VPs/network.

Hello guys, I 've been reading the protocol specification, and I have a couple of questions...
cbruguera
2016-07-05 15:01
1) "there is no expiration/revocation of ECerts"... Why is that so? Isn't there any mechanism thought in case a user might lose his certificate/keys or have it stolen somehow? Any thoughts on this?

2016-07-05 15:02
2) "it is recommended to only enable the REST service on non-validating peers on production networks"... Why is this so?

Well, I'll make use of the occasion to ask a third question (probaly this has been asked before)...
cbruguera
2016-07-05 23:54
3) All certificate issuance is done by "certificate authorities" (depending on the type of certificate to be used) which so far looks like a single Membership Svc. Server within the network... Are there any plans to further decentralize (or even distribute) such functionality so that there is not a single point of failure in the handling of certificates?
jonathanlevi
2016-07-06 00:18
@cbruguera: Hi Carlos, you can see/read/discuss more about these in #, but specifically to this question it really depends on your definition of single PoF
cbruguera
2016-07-06 00:19
Well, if such server fails, no certificates can be issued.
jonathanlevi
2016-07-06 00:19
While we don't have replication across domains, etc... you can distribute the load and the responsibility and actually delegate roles and affiliations... to make it much more scalable.
jonathanlevi
2016-07-06 00:19
OK, thanks for clarifying.
jonathanlevi
2016-07-06 00:20
So, you can have more than a single server issuing certificates
jonathanlevi
2016-07-06 00:20
You can have several ECAs, TCAs, etc...
cbruguera
2016-07-06 00:20
Ok, so is there some mechanism for distributing such task?
jonathanlevi
2016-07-06 00:20
Nope, but I'm actually working on something along these lines.

At the moment, you can see the tests... they create a new ECA and a TCA object (struct)
jonathanlevi
2016-07-06 00:22
Which later on, accept say 'Certficate Signing Requests'
jonathanlevi
2016-07-06 00:22
(of specific sorts, OK? I'm generalizing)
cbruguera
2016-07-06 00:22
Yeah, that would be more elegant (and blockchain-like)
jonathanlevi
2016-07-06 00:22
We do agree that the Certs processing (not issuing) can be hangled 'off-line'
jonathanlevi
2016-07-06 00:23
Yup, I'm totally there. I don't want to work with the direct objects AT ALL, tbh.
cbruguera
2016-07-06 00:23
However, I was pondering how crazy it was to rely the certificate handling to the network itself... Like taking the CA code and make it into smart contracts, maybe using some sort of "shared computation", so that the "authority" is the network, truly decentralizing certificate issuance (even within a permissioned network, decentralization is important)
jonathanlevi
2016-07-06 00:24
I'm doing some refactoring, so that you/one can launch the services, register available functions that are exposed, and then 'consume'
jonathanlevi
2016-07-06 00:24
Hmmm.... First of all, 'crazy' designs/notions are rarely crazy :wink:

Using "/chaincode" service I didn't find a way to pass the idGenerationAlg parameter. So my question is should this field be deprecated? or should /chaincode service be modified to support this parameter?

https://github.com/hyperledger/fabric/blob/master/docs/API/SandboxSetup.md
peer network login <username>
for example :
peer network login admin
Enter password for user 'admin':
I tried :
admin: 1 Xurw3yU9zI0l institution_a 00001
WebAppAdmin: 1 DJY27pEnl16d institution_a 00002
lukas: 1 NPKYL39uKbkj bank_a 00001
system_chaincode_invoker: 1 DRJ20pEql15a institution_a 00002
diego: 1 DRJ23pEQl16a institution_a 00003
jim: 1 6avZQLwcUe9b bank_a 00004
binhn: 1 7avZQLwcUe9q institution_a 00005
alice: 1 CMS10pEQlB16 bank_a 00006
bob: 1 NOE63pEQbL25 bank_a 00007
assigner: 1 Tc43PeqBl11 bank_a 00008
but none of them worked
I assumed that "DJY27pEnl16d" is the password encrypted for admin
am I right ?
where can I get the enrolledPWD ?

Hi, hoping yall can help me out with a problem I'm having. I have a Chaincode, where I'm routing all of my chaincode calls through Query because that seems to be the only where I can customize the data that gets returned. I basically use the Query as a handler, which then routes the transaction to another function.
Now the problem Im having is that checking the peer logs, it gives me a QUERY_ERROR "(Cannot put
state in query context). Notify"
Why am I not allowed to do a PUT_STATE just because my initial call to the chaincode was a query? So am I stuck with having to use invokes, but not being able to return my own JSON string in the message field like I can with query?
nkunkel
2016-07-13 04:24
With an invoke, I only get a status OK that the chaincode received my transaction, but this is prior to execution. If I run into an error, it won't return the error in a REST response. With a query, the execution is done first, so if an error is encountered during execution, a REST response containing the error is returned to the client.
simon
2016-07-13 09:02
nkunkel: because that's how it works. query is read-only and synchronous, invoke can write, but is asynchronous
nkunkel
2016-07-13 15:48
Okay I get for performance reasons you want to have asynchronous calls. However, from a usability standpoint then, you have to find some other solution, for error handling/reporting back to the client. If the solution is to write my error to the blockchain and query right after every single invoke, that can't possibly scale. Is there another way fabric goes about this that I'm missing?
ghaskins
2016-07-13 15:50
@nkunkel: the support is still emerging, but you will want to tap into the event mechanism
ghaskins
2016-07-13 15:50
that will allow you to close the loop on an otherwise async operation
ghaskins
2016-07-13 15:51
note that this is how all blockchains generally operate...
ghaskins
2016-07-13 15:51
out of necessity
nkunkel
2016-07-13 15:51
I understand why, performance is going to be key if the blockchain is to succeed.
ghaskins
2016-07-13 15:52
well, its all relative
nkunkel
2016-07-13 15:52
So this event mechanism, will it be able to communicate with the original client at all? Could you explain a little more how it will work?
ghaskins
2016-07-13 15:53
I am not on the team doing the work, so I only have a high level understanding, but the basic concept is there is a way to subscribe to published events that a properly authorized client may tap into
ghaskins
2016-07-13 15:53
one of those events could be the completion status of an invoke
ghaskins
2016-07-13 15:54
so, if you wanted to emulate an “RPC” out of an invoke that has gone through consensus, on the wire you would be doing something like [uuid=invoke(params), register(uuid, oneshot), <wait for event>]
ghaskins
2016-07-13 15:55
and then getting the appropriate result once the event completes
cbruguera
2016-07-13 17:10
@ghaskins: Where can I read detailed info on this event mechanism?
ghaskins
2016-07-13 17:11

Should `building build/docker/bin/peer` take too long?
ghaskins
2016-07-13 17:30
define “too long” ?
ghaskins
2016-07-13 17:31
i think under most circumstances, a rebuild should be on the order of a handful of seconds and a fresh build may take 30-45s
ghaskins
2016-07-13 17:31
depending on your environment, cpu, network connection, etc
ghaskins
2016-07-13 17:32
is “too long” in the order of 45s? >> 45s ?
cbruguera

cbruguera
2016-07-13 17:39

cbruguera
2016-07-13 17:41
where is the log file located?
cbruguera
2016-07-13 17:43
The thing is that after getting the VM up, there was not even a fabric-baseimage, so I guessed the build could take some time... But it's been like too long already.
ghaskins
2016-07-13 18:00
@cbruguera: the whole build from scratch only takes a minute or two on my 2009 MacPro 2.93Ghz Nehalem 4c system with 16G RAM and a 70MB/s internet connection
ghaskins
2016-07-13 18:00

ghaskins
2016-07-13 18:00

cbf

yes, well, the image for peer and membersrvc could probably be run in Alpine
cbf
2016-07-13 19:04
not clear why we need all of Ubuntu
ghaskins
2016-07-13 19:05
yeah, certainly for producing a final run target that makes a lot of sense
ghaskins
2016-07-13 19:05
for vagrant/devenv, ubuntu probably makes more sense
ghaskins
2016-07-13 19:06
at the time, the goal was to unify them
ghaskins
2016-07-13 19:06
but now that the build system is a little more sophisticated, it could probably target things more precisely

@nkunkel @ghaskins : I ran into the same problem when I want to implement the feature pay-per-query in chaincode. In order to support higher user concurrencies, I am thinking if I can change to pay by lease:
1. user Invoke the chaincode to pay for his lease for next 30 minutes
2. user Query the chaincode. In Query function, we compare current time to the end of his lease.
But I want to know if I can get the current time in chaincode. And there is another problem that time is not synchronized between validator nodes.
zuowang
2016-07-14 06:47
One more thing, how to get the return value of Invoke funtion? If we choose to return through payload in SetEvent(name string, payload []byte), then someone register with eventName = '' or '*' will see it.

@cbf: I know you opened a git issue about fabric components and naming. Given the consensus V2 concept as well as modularizing membership services / PKI / CA (whatever we decide to call it) is now the right time to create top level projects under hyperledger org for both of these?
cbf
2016-07-14 16:11
@garisingh: yes, but before we do, i think we need to sort out maintainers question… eg do we want to have/keep same maintainers for the new repos? I ask because the new work is actually new work and we need to maintain the old code for a while as deprecated but maintained.
cbf
2016-07-14 16:13
As such, I think that we should make formal proposal as we have been discussing (e.g. via a PR that the current maintainers agree to)
garisingh
2016-07-14 16:13
Agreed. I would propose that we have a more focused set on maintainers added to the new projects ( of course we can kept the current maintainers on those lists as well if they want to be on)

@zuowang: Regarding timestamps, you can get the transaction timestamp from the stub and store it as the time against which the lease can be compared. But you raise a good point in that a query may not have access to the equivalent of a transaction timestamp. So I wrote a snippet of code:
// just testing this trick
txnunixtime, err := stub.GetTxTimestamp()
if err != nil {
err = fmt.Errorf("Error getting transaction timestamp: %s", err)
log.Error(err)
return nil, err
}
txntimestamp := time.Unix(txnunixtime.Seconds, int64(txnunixtime.Nanos))
fmt.Println("***** QUERY reads txntimestamp: ", txntimestamp.Format(time.RFC3339Nano))
return assetBytes, nil
And got a result that shows that the chaincode always has access to the time of invocation of the function.
***** QUERY reads txntimestamp: 2016-07-14T18:05:43.248880214Z
18:05:43.257 [shim] DEBU : [ff94348e]Query completed. Sending QUERY_COMPLETED
So all you need to do is use that snippet of code to capture the transaction time in your invoke and store it into world state. Then perhaps set a timer in your app and start polling perhaps 5 seconds before the expiry and act on it when the time difference in the query exceeds the lease time.
cbf

kletkeman
2016-07-15 13:38
@zuowang: Glad it's useful for you. My suggestion was for the app that determines that the lease is over, which it can easily do by polling a query that returns the lease state (which contains the start timestamp). Of course, the app could actually choose to expire the lease with its own timer, but I would probably use the blockchain query to officially expire it (and post that as an event to be added to the state). With a short grace period, the customer can then be given the option to extend and that recorded as another event against the lease, which is then restarted. Rinse, repeat :slightly_smiling_face:

@kletkeman: You are right! I was thinking setting an fixed lease (30 min) when user Invoke the chaincode:
UserA -----------Invoke------------> Chaincode(decrease UserA's token, record UserA->CurrentTxTime)
UserA------------Query------------> Chaincode(get UserA->CurrentTxTime, check if time.Now().Sub(CurrentTxTime) < 30 min)

there is a chaincode development mode, i think
simon
2016-07-18 12:19
where you run the chaincode outside of docker
ashnur
2016-07-18 12:19
what I saw was something inside vagrant inside docker

cbf
2016-07-18 13:36
correct - I updated the docs to make chaincode development clearer
cbf
2016-07-18 13:37
cbf
2016-07-18 13:37
I’d welcome any feedback
ashnur
2016-07-18 13:53
@cbf: seems to be working, but I still don't know how to have immediate feedback while working on it
cbf
2016-07-18 13:54
feedback is the same, via log messages etc but the benefit is that you don’t need to (re)deploy the chaincode everytime you iterate through the develop, compile, run cycle
cbf
2016-07-18 13:55
so the benefit isn’t better feedback but a tighter feedback loop
ashnur
2016-07-18 13:57
that's great, I see the value in it, obviously but I don't know how this is going to work (i am re-reading that chaincode-setup doc you just linked, hoping maybe there is some explanation there), and I couldn't get feedback through logging before either. Maybe I am using the wrong images? I am trying with yeasy/hyperledger-peer
ashnur
2016-07-18 14:00
@ashnur shared a file: https://hyperledgerproject.slack.com/files/ashnur/F1SLM306L/docker-compose_yml.yaml
ashnur
2016-07-18 14:05
@cbf so instead of deploy, i have to do this after build? http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#starting-and-registering-the-chaincode
cbf
2016-07-18 14:06
correct, then you can send invoke and query transactions
ashnur
2016-07-18 14:12
@cbf I think it's working, but because of my lack of experience with Go, I think I am messing up something around the logging part and that's why I don't see the output I expect
ashnur
2016-07-18 14:13
I do see the “Received REGISTERED” message
muralisr
2016-07-18 14:19
@ashnur: you could use a query to verify expected result.
ashnur
2016-07-18 14:20
i could, if I had a brain, but that's for smart people :smile:
ashnur
2016-07-18 14:20
thanks @muralisr
ashnur
2016-07-18 14:20
i was trying with invoke

ashnur
2016-07-18 14:30
this is what I am getting :disappointed:
muralisr
2016-07-18 14:30
ok. I suspect the deploy did not go through
muralisr
2016-07-18 14:30
you are using —peer-chaincodedev mode ?
ashnur
2016-07-18 14:30
yup, i already shared my docker-compose file a few lines above
ashnur
2016-07-18 14:31
wait. do i have to deploy AND register?
muralisr
2016-07-18 14:32
you need to just deploy…
muralisr
2016-07-18 14:33
can you share your chaincode command line and the deploy command line ?
ashnur
2016-07-18 14:39
I thought I don't have to deploy, just register
ashnur
2016-07-18 14:39
what is chaincode command line?
muralisr
2016-07-18 14:40
I meant the command you ran the chaincode with
ashnur
2016-07-18 14:41
it's in the docker-compose.yml file I shared above
muralisr
2016-07-18 14:42
you do have to “deploy” even when running the chaincode yourself in -peer-chaincodedev mode to have the “Init” method called
ashnur
2016-07-18 14:43
yeah, i did deploy now, and then ran REGISTER again, but nothing changed
muralisr
2016-07-18 14:44
I see "peer node start --peer-chaincodedev” in yaml file but I was asking about the chaincode execution itself
muralisr
2016-07-18 14:44
so here’s what I do
muralisr
2016-07-18 14:45
CORE_PEER_ADDRESS=127.0.0.1:30303 CORE_CHAINCODE_ID_NAME=mycc ./mychaincode
muralisr
2016-07-18 14:45
and
muralisr
2016-07-18 14:46
./peer chaincode deploy -n mycc -c ‘{“Function”:”f”, “Args”:[“a”, “100”, “b”, “200”]}'
muralisr
2016-07-18 14:47
with the peer running in —peer-chaincodedev (as in your yaml)
ashnur
2016-07-18 14:48
muralisr: `peer chaincode query -u jim -p local-dev -n poc001 -c '{"Function":"invoke", "Args": ["a","100", "b", "200"]'}`
muralisr
2016-07-18 14:48
and deploy ?
ashnur
2016-07-18 14:48
`peer chaincode deploy -u jim -n poc001 -p local-dev -c '{"Function":"init", "Args": ["a","100", "b", "200"]}'`
muralisr
2016-07-18 14:48
ok
muralisr
2016-07-18 14:49
I assume your chaincode is running like so `CORE_PEER_ADDRESS=127.0.0.1:30303 CORE_CHAINCODE_ID_NAME=poc001 ./mychancode`
muralisr
2016-07-18 14:49
?
ashnur
2016-07-18 14:50
muralisr: `CORE_CHAINCODE_ID_NAME=poc001 CORE_PEER_ADDRESS=0.0.0.0:30303 ./local-dev`
muralisr
2016-07-18 14:51
ok
ashnur
2016-07-18 14:51
this is why I asked what is the minimum valid chaincode :slightly_smiling_face:
muralisr
2016-07-18 14:51
if you see “Received REGISTERED” message you shoukd be good to go
muralisr
2016-07-18 14:52
(and I see you did get that)

Does the `membersrvc` need to be restarted everytime a change is made to membersrvc.yaml? (in order to register a new user, for example)
sergeybalashevich
2016-07-18 19:44
membersrvc imports information from membersrvc.yaml at first start only. If you would like to re-import changes from yaml, you have to delete existing configuration from “/var/hyperledger/production/.membersrvc/“ at first, then restart membersrvc.

@codascud: if you run only one peer, this is expected output. If you run another peer connecting to this one..output will display you all the connected peers.
codascud
2016-07-19 16:08
Thanks @nhrishi but is there a reason why there is a spike in the outbound traffic? Is fabric trying to reach some external server (or peer)?

we posted a question on # channel but thought it would be more appropriate here:
we are seeing some unexpected behavior when trying out hyperledger fabric...we set up our own network with 3 validating peers (using pbft consensus) and pushed deployed some chaincode and did some invoke/query transactions....then we added another validating peer to the network and queried (using REST endpoint) the newly added peer about the block chain length (`/chain/blocks`) and found that it is always `1`. So when we try to do `query` of already deployed chaincode then it fails saying transaction id not found....we tried with `noops` consensus also and saw the same behavior...are we missing something?
we waited for more than 5 mins to make sure that it is not a timing issue (the total block chain height was 4 so it shouldn't have taken long for syncing)
kostas

@atulkc: Dynamically adding peers after the network has been configured/created is not supported yet.

Not sure if this helps and assumes this is test environment and can be recreated. I see this error when I run new membersrvc, and keyvalue store of Node.JS client (e.g. /tmp/keyValueStore) was not deleted with the new membersrvc instance. Try to delete keyvalue store if you have new membersrvc.

I have a question for the fabric team
virajkamat
2016-07-22 11:13
We have several institution that want to interact with each other and maintain a common ledger. Each transaction that is initiated by a party contains information of that party and another party involved in the chain. We do not want the transaction to reach a third institution as it has no connection with the transaction. The intention is to avoid executing the chain code at a part that is not connected with the transaction.
virajkamat
2016-07-22 11:13
How could we achieve this, what sort of features do you have under development or are proposed for development that can achieve this functionality.
muralisr
2016-07-22 11:37
@virajkamat: this type of requirement maybe better addressed in the next consensus architecture proposalhttps://github.com/hyperledger/fabric/wiki/Next-Consensus-Architecture-Proposal

2016-07-22 11:43
Im guessing there is no feature present as of now. Is this issue addressed in the next Consensus architecture protocol

What if a confidentiality policy is applied. In that case will the data be hidden from the endorsing peer not allowed to view the data

I read the spec of hyperledger/fabric. I don’t see any thing about proof of work. I just see it mentions proof of agreement. Could you please tell me about proof of work, proof of agreement on hyperledger/fabric?
tuand
2016-07-23 17:35
fabric uses PBFT as its consensus algorithm ( chapter 5 in the protocol-spec doc ), not proof of work. We're also working on a new architecture https://github.com/hyperledger/fabric/wiki/Next-Consensus-Architecture-Proposal that will allow plugins of other consensus protocols

Hey guys
virajkamat
2016-07-25 04:11
We have several institutions that want to interact with each other and maintain a common ledger. Each transaction that is initiated by a party contains information of that party and another party involved in the chain. We do not want the transaction to reach a third institution that has no connection with the transaction. The intention is to avoid notifying a party that a transaction happened when the transaction is not relevant to the party. The transaction should be seen by only the 2 parties that are involved in it. Confidentiality of the transaction is not the objective of doing this. We want to avoid other parties spending computational resources on the transaction.
If the result of the computation reaches all peers, we don’t mind. But the cause of the change should not make it to peers other than the ones involved in the transaction.
At the transaction level, is it possible to specify the peers that will be made aware of the transaction. It is acceptable that the result of the transaction will be made available to all peers.

@virajkamat: I'm not sure how much of what you're asking for is available in pbft consensus, but you might want to read this: https://github.com/hyperledger/fabric/wiki/Next-Consensus-Architecture-Proposal
bgorman
2016-07-25 05:25
does anyone here know if peers are meant to recover if they "miss" a transaction due to being offline?
My scenario is vp0 thru vp3 running pbft. Then vp0 goes offline (docker stop vp0), while a transactions occurs on another peer. Then vp0 comes back up (docker start vp0) and it never seems to learn of the transaction that happened while down. Any transactions on vp0 is never replicated to the other peers and the same goes for the other peers transactions not replicating to vp0.
I just end up with repeated logs like this:
`05:24:45.151 [consensus/pbft] sendViewChange -> INFO bac Replica 0 sending view-change, v:1, h:0, |C|:1, |P|:2, |Q|:3`
`05:24:45.152 [consensus/pbft] recvViewChange -> INFO bad Replica 0 received view-change from replica 0, v:1, h:0, |C|:1, |P|:2, |Q|:3`
`05:24:45.152 [consensus/pbft] recvViewChange -> WARN bae Replica 0 already has a view change message for view 1 from replica 0`
ashishkel
2016-07-25 06:51
@bgorman: if i remember correctly, that depends on the consensus setup.
ashishkel

and there is some formula in case of pbft, on the basis of which a lagging node catches up..

i mean the catchup is triggered only if that formula's condition is satisfied.
bgorman
2016-07-25 06:53
ok... I'm running batch pbft with the default settings
I came across this issue as well which seems very relevant
https://github.com/hyperledger/fabric/issues/1331
bgorman
2016-07-25 06:54
currently running 500-ish transactions to see if it makes my lagging node catch up
ashishkel
2016-07-25 06:54
YEs,
ashishkel
2016-07-25 06:54
thsi issue was even what i was looking to point you to :_
ashishkel
2016-07-25 06:54
:slightly_smiling_face:
bgorman
2016-07-25 06:55
haha, I can't even query my laggard peer now...
Error: Error querying chaincode: rpc error: code = 2 desc = "Error: state may be inconsistent, cannot query"
ashishkel
2016-07-25 06:55
there somewhere towards the end, this formula of 2f+1 or something was quoted.
ashishkel
2016-07-25 06:55
oh man.. :wink:
bgorman
2016-07-25 06:56
yeah ok, you mean how pbft tolerates (n-1)/3 failures in an 'n' node network
ashishkel
2016-07-25 06:57
oh yea , sorry my bad.. my memory with mathematical stuff is horrible :slightly_smiling_face:
bgorman
2016-07-25 06:57
I didn't think it was meant to leave the failing nodes permanently behind though
bgorman
2016-07-25 06:57
there's nothing wrong with my laggard peer, it just missed one transaction while it was offline
ashishkel
2016-07-25 06:58
but it also said, that the catch up will start once the number of proper nodes is below some number..
bgorman
2016-07-25 06:59
yeah I'm doing the same to a second node now... to see if it helps
bgorman
2016-07-25 06:59
2/4 should not be tolerated
ashishkel
2016-07-25 07:00
all the very best :slightly_smiling_face:
bgorman
2016-07-25 07:00
wow.... it actually seems to have caught them all up
bgorman
2016-07-25 07:00
that seems .... odd
ashishkel
2016-07-25 07:01
u mean, it worked ?
ashishkel
2016-07-25 07:02
then u shd be happy, i guess?
bgorman
2016-07-25 07:13
yeah I am reasonably happy they caught up, but it's weird that 1/4 is perfectly happy in never being able to catch up on its own
bgorman
2016-07-25 07:13
if you happen to be querying the node that's behind, you will never know that you're getting old data
bgorman
2016-07-25 07:28
it looks like the height of the blockchain on the laggard peer does not increase despite invoking on it, so perhaps I just need to run many more transactions on the laggard
bgorman
2016-07-25 07:44
so I'm running 5000 transactions against the laggard... it is consistently a number of blocks behind the other peers
358-300-358-358
728-720-728-728
876-840-876-876
etc
bgorman
2016-07-25 08:03
same thing happens if I swap to running transactions on the up-to-date peers... the laggard never fully catches up, but it does move on from the original state
ashishkel
2016-07-25 08:43
that means, the consensus messages of the current transactions [ occurring on other nodes ] are being received by the lagging node. Okay...
ashishkel
2016-07-25 08:44
and the new transactions on the laggin nodes do get distributed to the other nodes..
ashishkel
2016-07-25 08:45
and the only problem the transactions which it missed while it was down... is it?
simon
2016-07-25 10:16
bgorman: just inject more transactions
simon
2016-07-25 10:16
bgorman: it is normal that f peers will be behind
simon
2016-07-25 10:17
bgorman: you can't tell whether they are byzantine or just slow

so I spent this afternoon on something that is probably very obvious to people on the channel.. well, it was not too me! So.. perhaps you will find it useful.. I was trying to deploy chaincode that happens to be on my own branch of hyperledger.. i.e. https://github.com/vpaprots/fabric/tree/laszlo-branch/examples/chaincode/go/ingredients
which took me for a trip of errors: https://github.com/hyperledger/fabric/blob/master/core/chaincode/platforms/golang/hash.go
so.. I got to prefix things with http/https.. fine, didnt know that.. so, did that and `you still no wonky work!`.. next spread some unwelcome attention onto `go get` command...

Hi

I had asked this question earlier and was told to refer to the Consensus architecture proposal. I couldn't find anything relevant to it. I was hoping someone could have a look at our requirements and shed light on the following query:
We have several institutions that want to interact with each other and maintain a common ledger. Each transaction that is initiated by a party contains information of that party and another party involved in the chain. We do not want the transaction to reach a third institution that has no connection with the transaction. The intention is to avoid notifying a party that a transaction happened when the transaction is not relevant to the party. The transaction should be seen by only the 2 parties that are involved in it. Confidentiality of the transaction is not the objective of doing this. We want to avoid other parties spending computational resources on the transaction.
If the result of the computation reaches all peers, we don’t mind. But the cause of the change should not make it to peers other than the ones involved in the transaction.
At the transaction level, is it possible to specify the peers that will be made aware of the transaction. It is acceptable that the result of the transaction will be made available to all peers.
How can we achieve this ?
simon
2016-07-26 11:40
virajkamat: how are they then maintaining a common ledger?
simon
2016-07-26 11:41
if we have party A, B, C, and a transaction between A and B happens, and C shouldn't get it, doesn't that mean that there is no common ledger between A B and C, but only between A and B?

We've talked about this previously. Now is the time to transition to Gerrit and Jira for the Fabric project. Many are at the Hackfest here in SF, but for those who are not, we'll have to be adapting our workflow to using Gerrit.
The rationale for transitioning to Gerrit is to a) provide much more governance over the IP hygiene by enforcing the DCO sign-off on every commit merged (no exceptions). We did not have this level of rigor on GitHub. b) to enforce that no maintainer can merge their own commits. c) to enforce a rule that requires multiple reviewers to agree to a merge.
This may slow things down initially until we all get the swing of the new flow, but it will give us higher quality code and much better IP assurances.
The Gerrit repo will be here: https://gerrit.hyperledger.org/r/#/admin/projects/fabric
Currently, the code is in the process of being migrated over. There's an active review here https://gerrit.hyperledger.org/r/#/c/255/ for the initial commit of code to Gerrit. Once that is merged by the maintainers, everyone will need to clone that repo for their development going forward, and do git pushes to Gerrit. Basically, I have copied the GH code into a pristine git repository at the behest of LF so that we can benefit from the IP hygiene hooks in Gerrit that assure that every commit carries a DCO sign-off.
To submit code for review, you will need a Linux Foundation ID here: https://identity.linuxfoundation.org/ . Simple enough,if you have an ID, you are set. If not, please create one. This will grant you SSO across the LF tools portfolio.
Add your SSH key to Gerrit
1. click on your profile (upper right hand corner) and select 'Settings' and then 'SSH Public Keys'
2. from a terminal window: pbcopy < ~/.ssh/id_rsa.pub
3. paste into the Gerrit window for your SSH key
4. press 'Add' button
So, the new workflow would be as follows:
1. Clone the Gerrit repository.
1.a from the Projects menu in Gerrit, click 'list' in the LF corner.
1.b from the list of projects, select 'fabric'
(note, you will want to PRESERVE your previous Fabric repository clone because you may want to be able to push any outstanding PRs to Gerrit by copying the source from your GH clone to the Gerrit clone).
1.c from the project window, select 'Clone with commit hook' and then copy the command and paste to a terminal window to clone the repository into your $GOPATH/src/github.com/hyperledger folder.
2. make your changes
3. commit your code
4. git push origin HEAD:refs/for/master
The GH fabric repo will remain in read-only mode until we establish the mirror from Gerrit. We will preserve the current state of the hyperledger/fabric repo (and all subsequent transitioned repositories) for posterity at a location TBD (likely something like 'hyperledger-archive' org on GH).

jcarrivick

@cbf: All good I figured it out, I was using my email address instead of my username haha
ghaskins
2016-07-27 01:58
@cbf: can you clarify one thing: when you go to the identity site above, it lets you do SSO through providers like github…but when you go to gerrit, it only seems to present username/password
ghaskins
2016-07-27 01:58
do you know if the SSO logins work or do we need an explicit LF account
cbf
2016-07-27 02:46
I think that we maintainers need an account @ry would know
ry
2016-07-27 03:01
@ghaskins: you will need an LFID. If you create it with the same email as you use for github, then you can use social logins
bgorman
2016-07-27 03:30
with this move to Gerrit, what is happening with issue tracking? Is it remaining on Github?
bgorman
2016-07-27 03:31
or does Gerrit do issue tracking and I just can't see it
bgorman
2016-07-27 03:44
ah, thanks :smiley:
bgorman
2016-07-27 03:47

that is a question for cbf, he found a tool to do the porting but it seemed to pull in everything (pull requests as issues, for example) and I’ve been too busy to mess with it this week
ry
2016-07-27 03:48
I suspect the answer is “yes” but I can’t say when
bgorman

Will it work if I just `git remote add` the new repository at Gerrit to my existing local Fabric repo and make further pulls from it? (not needing to clone anything)
cbruguera
2016-07-27 23:11
...Or maybe it's recommended to clone, since the paths will be different? (no more `$GOPATH\src\http://github.com` ?)
ray
2016-07-27 23:32
Since we migrated to Gerrit, will the old repo on GitHub acting as a mirror repo (i.e. further commits will still be synced to GitHub) ? Or it won't be updated anymore?

ghaskins
2016-07-28 16:34
is there some other policy, etc?
cbf
2016-07-28 16:34
right NOW, the enforcement is basically one +2 by other than OP
cbf
2016-07-28 16:34
I have asked @ry to look into 2+2 NYOC (not your own code)
ghaskins
2016-07-28 16:34
ok, right now we have two +2s but I know we had a bunch of +1s in the GH thread
ghaskins
2016-07-28 16:34
(I know you wanted quorum on this one)
cbf
2016-07-28 16:35
we could do socially 2+2 until he can find the rule
ghaskins
2016-07-28 16:35
ok, that sounds good to me
ghaskins
2016-07-28 16:35
after all, we did fine with the relative lax GH environment (no self-commit abuse)
ghaskins
2016-07-28 16:35
so, social rules are fine for now
ghaskins
2016-07-28 16:35
(IMO)
cbf
2016-07-28 16:35
on the maintainer policy one (and any others that affect maintainer policy), I would like super majority of maintainers
cbf
2016-07-28 16:36
yes, I agree
ghaskins
2016-07-28 16:36
ok..i think we have it OOB, but not within gerrit
ghaskins
2016-07-28 16:36
ill hold off for now
cbf
2016-07-28 16:36
WDYT about the 2+2
cbf
2016-07-28 16:36
?
ghaskins
2016-07-28 16:36
Policy wise, I think it makes sense
ghaskins
2016-07-28 16:36
bandwidth wise, I think we are already strapped
cbf
2016-07-28 16:36
+2
cbf
2016-07-28 16:36
yeah, agree
cbf
2016-07-28 16:36
but we just added 4
ghaskins
2016-07-28 16:36
but that should hopefully improve with you and @hgabor et al
cbf
2016-07-28 16:36
so we are 8 now
ghaskins
2016-07-28 16:36
right
ghaskins
2016-07-28 16:37
so, its probably fine
ghaskins
2016-07-28 16:37
i say, go for social 2+2, if its painful, we can revisit
cbf
2016-07-28 16:37
we could do a social approach and major changes require 2+2
cbf
2016-07-28 16:37
or that
ghaskins
2016-07-28 16:38
yeah, that sounds good
ghaskins
2016-07-28 16:38
so, maintainer rule change, big change, social 2+2
cbf
2016-07-28 16:38
we could recommend that if the patch seems significant, add another reviewer
ghaskins
2016-07-28 16:38
trivial change, single non-op +2 good?
cbf
2016-07-28 16:38
+2
ghaskins
2016-07-28 16:38
cool, any one else have a thought?
cbf
2016-07-28 16:38
non-op is enforced
ghaskins
2016-07-28 16:39
right, thats nice
ghaskins
2016-07-28 16:39
not that anyone has or is expected to violate, but if for anything, to prevent accidents
ghaskins
2016-07-28 16:39
(it was too easy to leave a git-remote in GH)

2016-07-28 16:40
too easy for a stray unqualified “git push” to do damage, heh
ghaskins
2016-07-28 16:41
I feel reasonably confident merging 291 because the GH PR had a quorum of effective +2s already
ghaskins
2016-07-28 16:41
or should I wait?

2016-07-28 16:42
I agree, I don’t recall any dissent

Do you know how to create a sigma/ proof of identity using sdk/node or hfc?
ghaskins
2016-07-29 13:34
@cbf @ry one potential wrinkle with the current gerrit setup; go imports
ghaskins
2016-07-29 13:34
do we have a plan here?
ghaskins
2016-07-29 13:35
for instance “import ‘http://github.com/hyperledger/fabric'” has support for gotool to translate to https://github.com/hyperledger/fabric
ghaskins
2016-07-29 13:36
but not sure what that would look like now from http://gerrit.hyperledger.org/r/fabric
ghaskins
2016-07-29 13:37
does this mean all imports need to be refactored accordingly? does gotool support arbitrary URLs? Perhaps the github mirror will be utiliized such that we don’t need to change?
cbf
2016-07-29 13:47
I was thinking the mirror, yes
cbf
2016-07-29 13:47
I don’t know whether go can handle gerrit
cbf
2016-07-29 13:47
er gerrit gits
ghaskins
2016-07-29 13:47
yeah, it seems that the mirror is at least a good stopgap until we can figure thatout
ghaskins
2016-07-29 13:48
i have a sneaking suspicion that it might work with any path, though the gerrit one is a little ugly
ghaskins
2016-07-29 13:49
not sure we can do anything about that
cbf
2016-07-29 13:49
so, we need to 1) create an hyperledger-archives org 2) move hyperledger/fabric to hyperledger-archives/fabric and 3) mirror http://gerrit.hyperledger.org/r/fabric to hyperledger/fabric
ghaskins
2016-07-29 13:49
sounds reasonable
cbf
2016-07-29 13:50
and add the relevant README updates
ghaskins
2016-07-29 13:50
i wonder if the “/r/“ can be remapped
ghaskins
2016-07-29 13:50
thats really the only part that looks odd
cbf
2016-07-29 13:50
dunno
cbf
2016-07-29 13:51
but my point was does go have an ability to map http://gerrit.org.com/r/repo to actually fulfilling the git magic
cbf
2016-07-29 13:51
I don’t think so
ghaskins
2016-07-29 13:52
oh i see what you mean
ghaskins
2016-07-29 13:52
yeah, that I dont know
ghaskins
2016-07-29 13:52
i was assuming it was a standard git compatible url, but perhaps not
cbf
2016-07-29 13:52
right, it has some built in rule/assumptions as to what go get http://github.com/whatevs means
ghaskins
2016-07-29 13:52
actually, it should be, that is the URL that gerrit hands out for cloning
cbf
2016-07-29 13:52
let me try
ghaskins
2016-07-29 13:53
oh wait, i completely misunderstood you above
ghaskins
2016-07-29 13:53
i thought you were wondering if the /r thing was a real gerrit URL or synthesized
ghaskins
2016-07-29 13:53
i see now you are talking about the gotool mapping
cbf

the fact that it hit a TCP DNS lookup error is promising

hmmm
ghaskins
2016-07-29 13:54
hmm, wonder what that is
cbf
2016-07-29 13:54
maybe there’s some special sauce
ghaskins
2016-07-29 13:55
ghaskins
2016-07-29 13:56
not sure we have access to the http engine under gerrit
ghaskins
2016-07-29 13:56
but if its served over something like apache or nginx, should be trivial
cbf
2016-07-29 13:57
yes
cbf
2016-07-29 13:59
they actually have a gerrit example
cbf
2016-07-29 13:59
<meta name="go-import" content="example.org git https://code.org/r/p/exproj">
ghaskins
2016-07-29 13:59
perfect
cbf
2016-07-29 14:00
we could map “http://hyperledger.org/fabric” to "https://gerrit.hyperledger/r/fabric"
ghaskins
2016-07-29 14:00
my guess is @ry et. al. have this running under apache, but thats just a guess
ghaskins
2016-07-29 14:00
if so, I would imagine this can be configured fairly easily
cbf
2016-07-29 14:00
that would make the path much less convoluted
ghaskins
2016-07-29 14:01
that has my vote as the most desirable outcome
cbf
2016-07-29 14:01
eg $GOPATH/src/hyperledger/fabric instead of $GOPATH/src/github.com/hyperledger/fabric
cbf
2016-07-29 14:02
yes
cbf
2016-07-29 14:02
what I meant
ghaskins
2016-07-29 14:02
i think that reads nicely
ghaskins
2016-07-29 14:02
understood
cbf
2016-07-29 14:02
we can host a page there that could be the http://cbf-fabric-docs.readthedocs.io/en/latest/
ghaskins
2016-07-29 14:03
my assumption is this is a golang specific thing, so the sawtooth, etc, folks don’t need to have similar considerations
cbf
2016-07-29 14:03
right
ghaskins
2016-07-29 14:04
but good to know in general
ghaskins
2016-07-29 14:04
I assume we are going to move GH::Issues to JIRA or something at some point?
cbf
2016-07-29 14:04
but it also suggests that we start to federate the child repos from the main fabric repo
cbf
2016-07-29 14:04
eg add a section to README that basically lists the related projects
ghaskins
2016-07-29 14:05
i assume you mean like -api and -chaintool
cbf
2016-07-29 14:05
and integrate the docs for those into the main fabric doc tree
cbf
2016-07-29 14:05
yes
ghaskins
2016-07-29 14:05
yeah, that sounds good
ghaskins
2016-07-29 14:05
the last thing to consider, i’ve been using the GH::Releases facility
cbf
2016-07-29 14:06
ok, going to write this up
ghaskins
2016-07-29 14:06
if I moved -chaintool to gerrit, i lose that
ghaskins
2016-07-29 14:06
any thoughts on how to handle?
cbf
2016-07-29 14:06
unfamiliar with that
cbf
2016-07-29 14:06
looking
ghaskins
2016-07-29 14:06
well, fundamentally its about git tagging
ghaskins
2016-07-29 14:06
but GH has a value add on top where you can attach artifacts
ghaskins
2016-07-29 14:07
so, for instance, I can provide a URL like this: https://github.com/hyperledger/fabric-chaintool/releases/download/v0.8.1/chaintool
ghaskins
2016-07-29 14:07
which is particularly convenient for a JVM payload since its $arch neutral
ghaskins
2016-07-29 14:07
I can just have users wget that link and be up and running
cbf
2016-07-29 14:07
and we can’t translate that to gerrit/git
cbf
2016-07-29 14:07
?
ghaskins
2016-07-29 14:07
so, the tagging part should be universal in git, including gerrit
cbf
2016-07-29 14:08
yes
ghaskins
2016-07-29 14:08
but as far as where the artifact hosting might reside, its unclear
ghaskins
2016-07-29 14:08
(perhaps we can’t/don’t-want-to, and then I just need to use a different strategy
cbf
2016-07-29 14:08
LF has object storage
cbf
2016-07-29 14:09
for build/release artefacts
ghaskins
2016-07-29 14:09
ok, that might work
ghaskins
2016-07-29 14:09
i suspect it wont be as turnkey as the GH::Releases thing, but se la vie
cbf
2016-07-29 14:09
so there’s a tool that builds the release notes and puts artefacts somewhere in gh?
ghaskins
2016-07-29 14:10
no, that part is still manual
cbf
2016-07-29 14:10
we can automate;-)
ghaskins
2016-07-29 14:10
(actually, i shouldnt say “no"
ghaskins
2016-07-29 14:10
rather, I am not sure, so I do it manually
cbf
2016-07-29 14:10
I like the format
ghaskins
2016-07-29 14:10
yeah, this is true…jenkins or whatever could promote release artifacts to a repo for us
ghaskins
2016-07-29 14:10
that would be even better than what we have now actually
cbf
2016-07-29 14:11
is there a way to include release notes culled (and curated) from the git log?
ghaskins
2016-07-29 14:11
my experience is, its all in how creative the CI admin is
ghaskins
2016-07-29 14:11
generally, yes
cbf
2016-07-29 14:11
<--
ghaskins
2016-07-29 14:12
were you asking about automation from GH::Releases ?
cbf
2016-07-29 14:12
w/r/t 0.5-developer-preview, we can leave that where it is, no?
cbf
2016-07-29 14:13
yes
ghaskins
2016-07-29 14:13
i am not aware of that, I just get a chance to write one each time I create a release
ghaskins
2016-07-29 14:13
but from Jenkins, I think we could automate it easily
ghaskins
2016-07-29 14:14
obviously if the maintainers/contributors dont do anything special like curate a release-notes.txt, the info available to automate is more limited
ghaskins
2016-07-29 14:14
like git-log output (which is still helpful IMO)
ghaskins
2016-07-29 14:15
but its generally better if there is someone making intelligent release notes as part of release management, and then jenkins can just react to that
ghaskins
2016-07-29 14:20
w.r.t. preview branch, are you thinking we just leave it in the RO GH tree?
ghaskins
2016-07-29 14:22

@cbf: A question @hgabor and I had for those of us new to Gerrit. If we’re reviewing a change, and we add comments that need addressing, but in general the change looks good, how do we vote or do we wait to vote?
cbf
2016-07-29 14:28
you can +1, 0 or -1 depending on how warm or cold you are to merging
sheehan
2016-07-29 14:28
thanks
cbf
2016-07-29 14:29
using a +2 with comments could just be “next time, don’t do X, but we’ll let it slide this time"
cbf
2016-07-29 14:29
-2 is a veto
cbf
2016-07-29 14:30
so even if someone +2 ed (pretty sure we have that set up)

@diego_m: when trying to use stub.VerifyAttribute() to verify a “role” attribute, I’m getting the following error:
[asset_mgm] ERRO : system error Failed retrieving extension.
through dlv debug it was returned from core/crypto/primitives/x509.go:135. what does this error mean and how to fix it?

@jzhang: from the error I think it means the TCert used for that transaction doesn’t have that attribute included
diego_m

could you tell me how did you generate the TCert and confirm is the role attribute is included on it?

@sheehan: @ghaskins @cbf About the gerrit review voting, i guess we can have a good reference from what the OpenStack project does: http://docs.openstack.org/infra/manual/developers.html I have contributed to it in past 3+ years, and feel the process is very robust/efficient :grinning:
jzhang
2016-07-30 15:32
@diego_m: thanks for the prompt response, I didn’t explicitly generate the TCert for the transaction submitter, I simply logged in from CLI (peer network login assigner), in membersrvc.yml the “assigner” ID has an attribute entry like this: `attribute-entry-11: assigner;bank_a;role;assigner;2015-01-01T00:00:00-03:00;;`. would it not get included in the TCert when this ID submits a transaction from CLI (or REST API for that matter)?

2016-08-01 16:38
@jzhang: yes, the assigner ID should have the role attribute, the only thing I can think of to cause that error is that probably you have old TCerts from a previous run for that ID.
jzhang
2016-08-01 16:39
so should I try rm -f /var/hyperledger/production then restart the network?
diego_m
2016-08-01 17:00
@jzhang: yes, let me know if that work

@diego_m: still getting the same error after stopping the membersrvc, stopping peer, deleting the /production, restarting membersrvc and restarting peer (using —peer-chaincodedev as before):
error in peer node console log:
`[chaincode] processStream -> ERRO 75b Got error: user is not aurthorized to assign assets: must be in role ‘assigner’`
error in chaincode console log:

18:14:10.104 [asset_mgm] ERRO : system error Failed retrieving extension.
```
jzhang
2016-08-01 18:19
and I did a `peer network login assigner` before deploying the chaincode `mycc`
diego_m
2016-08-01 18:19
I see, the other thing that could happen is that the aca is disabled in membersrvc.yaml
jzhang
2016-08-01 18:19
let me double check that
diego_m
2016-08-01 18:19
can you open that file, go to the aca section and check if the enable flag is set to true?
jzhang
2016-08-01 18:20
shoot, you are absolutely right, was “false” :wink:
diego_m
2016-08-01 18:20
:smile:
diego_m
2016-08-01 18:21
ok, you need to enable it and delete the production folder again
diego_m
2016-08-01 18:21
because now you have tcerts without that role
diego_m
2016-08-01 18:21
is the same rm you did before
jzhang
2016-08-01 18:21
for my credit :wink: I did check the console log which had `INFO: 2016/08/01 18:06:57 ACA services started`
jzhang
2016-08-01 18:22
i think the log message should be made more clear?
diego_m
2016-08-01 18:22
you are right
diego_m
2016-08-01 18:23
could you open an issue for that?
diego_m
2016-08-01 18:23
also you can take a look at this document for more details about the ACA and attribtues
diego_m
2016-08-01 18:23
jzhang
2016-08-01 18:27
will do
jzhang
2016-08-01 18:45
@diego_m: still no cigar, even tried to rebuild the membersrvc (make membersrvc) after modifying aca.enabled in membersrvc.yml, same error still
diego_m
2016-08-01 18:50
ok, just as a recap
diego_m
2016-08-01 18:51
you are trying to login with user assigner, get a TCert with the role attribute and invoke a chaincode function that verifies that attribute
diego_m
2016-08-01 18:51
right?
jzhang
2016-08-01 18:52
not sure what “get a TCert” entails, but here’s the series of commands I’m using:
```
peer network login assigner
CORE_SECURITY_ENABLED=true CORE_SECURITY_PRIVACY=true peer chaincode deploy -n mycc -c '{"Function":"init", "Args": []}' -u assigner
CORE_SECURITY_ENABLED=true CORE_SECURITY_PRIVACY=true peer chaincode invoke -n mycc -c '{"Function":"assignOwnership", "Args": ["-----BEGIN+CERTIFICATE——blahblah-----END+CERTIFICATE-----%0A","account1","100"]}' -u assigner
```
diego_m
2016-08-01 18:53
I see
diego_m
2016-08-01 18:53
ok, when you deploy, invoke or query TCerts are requested automatically if needed
diego_m
2016-08-01 18:54
if you want an attribute to be included in the TCerts you need to specify the attribute name during deploy, invoke or query
diego_m
2016-08-01 18:54
let me show you how
jzhang
2016-08-01 18:54
ah ok, that must be what i’m missing
diego_m
2016-08-01 18:54
diego_m
2016-08-01 18:55
that is part of the documentation I sent to you, in particular the line you need is:
diego_m
2016-08-01 18:55
(from that section)
diego_m
2016-08-01 18:55
./peer chaincode invoke -u userName -n mycc -c '{"Function":"increment", "Args": []}' -a ‘["role", "company"]'
diego_m
2016-08-01 18:55
there the user is invoking with attributes role and company, so it will get back TCerts with those attributes
diego_m
2016-08-01 18:56
it is the same for deploy, just pass -a ‘["role"]'
diego_m
2016-08-01 18:56
in your case
diego_m
2016-08-01 18:56
but again, you need to delete the old TCerts first
diego_m
2016-08-01 18:56
sorry, my mistake
diego_m
2016-08-01 18:56
you don’t need to delete the old TCerts
diego_m
2016-08-01 18:56
since you are now requesting TCerts with the attribute you will get new ones
jzhang
2016-08-01 18:59
that’s it! after adding the “-a” switch i got past that error. thanks @diego_m ! sorry for missing that in the doc :wink:

Hello HLP I have a question about chain code in a fail over scenario
james.buckett
2016-08-02 04:00
If i have four VP with chain code deployed
james.buckett
2016-08-02 04:00
and i lose one of the VP's
james.buckett
2016-08-02 04:00
I start a new VP
james.buckett
2016-08-02 04:00
how does the new VP get a copy of the chain code
jcarrivick
2016-08-02 04:03
@james.buckett: My understanding is that it should get distributed as part of the blockchain when the new VP connects to the network
jcarrivick
2016-08-02 04:04
Someone correct me if I'm wrong
bgorman
2016-08-02 04:05
I'm not sure you're allowed to have "new" peers join a network (if you set pbft N=4)
james.buckett
2016-08-02 04:05
If I have 4 VP and 1 dies
james.buckett
2016-08-02 04:05
and i start a new 1 then i am back at 4 again
bgorman
2016-08-02 04:05
do you mean new as in you lost the info on disk?
james.buckett
2016-08-02 04:06
correct
bgorman
2016-08-02 04:06
I have never had that work
baohua
2016-08-02 05:46
you should use the same name/id for the new starting vp node.

can anyone please help me to resolve this problem ?
bgorman
2016-08-02 06:57
@ankitkamra: I take it you've waited a bit and retried?
ankitkamra
2016-08-02 06:58
@bgorman: yes i waited for chaincode deployment
ankitkamra
2016-08-02 06:58
in my peer logs it first shows chaincode deployed successfully
ankitkamra
2016-08-02 06:59
after then when i query it returns the above error message
bgorman
2016-08-02 06:59
I think the "deploy" is asynchronous, so it returns a success when there's really still things going on in the background
ankitkamra
2016-08-02 07:00
@bgorman: may be i am not sure i have waited for 4-5 mins
ankitkamra
2016-08-02 07:01
also i m getting following error:-

bgorman
2016-08-02 07:02
if you run `docker ps -a` can you see any chaincode containers like `dev-vp1-9bdfbf948ccf88b9c09b6e0674feb413e2673d52d07285d7efb28e6e0d4f0e7ea3732b99c78fbddd1a2ea49d895b0f1248a1c9a4bcb864721af8c382d6b79e3d`
ankitkamra
2016-08-02 07:03
i can see two peers but both are in exited state
ankitkamra
2016-08-02 07:04
two containers**
bgorman
2016-08-02 07:05
you can try `docker logs containerName` to see what they printed out
bgorman
2016-08-02 07:05
I'm guessing something bad happened during the deployment
ankitkamra
2016-08-02 07:06
yes there is following error:-

Hi,
I am running the fabric setup in 'outside vagrant" mode using docker toolbox on windows 7.
I am able to get the peer and membersrvc up & running, but when I try to register the chain code using -
CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=0.0.0.0:30303 ./chaincode_example02
I get the following error -

bgorman
2016-08-02 07:39
@matpasha you seem to have the peer attempting to connect to the IP address 0.0.0.0 - I think you may want to check your address configurations
bgorman
2016-08-02 07:40
CORE_PEER_ADDRESS=0.0.0.0:30303 should be an addressable IP
bgorman
2016-08-02 07:40
not 0.0.0.0
bgorman
2016-08-02 07:41
usually for vp0 it'd be 172.17.0.2:30303 (although the new code has different ports)
matpasha
2016-08-02 07:42
@bgorman: Could you tell me how do i do that? FYI I tried the IP address of the fabric peer running on the same machine. I didn't work. Should I try I try the IP of membersrvc instead?
Also the where is the port 30303 configured? Doesn't seem to be listed in docker-compose.yml.
bgorman
2016-08-02 07:44
you could try setting CORE_PEER_ADDRESSAUTODETECT=true
bgorman
2016-08-02 07:44
the CORE_PEER_ADDRESS should be whatever hostname/IP that other peers can route to
bgorman
2016-08-02 07:44
for the peer being deployed
matpasha
2016-08-02 07:45
- CORE_PEER_ADDRESSAUTODETECT=true is already there
bgorman
2016-08-02 07:46
so it is
bgorman
2016-08-02 07:46
why did it not pick a good IP for the peer address then? :confused:
bgorman
2016-08-02 07:47
oh wait it's your chaincode registering that isn't working
bgorman
2016-08-02 07:48
you need to point it to the peer's address
bgorman
2016-08-02 07:48
so (1) figure out the peer's IP
bgorman
2016-08-02 07:48
(2) set it in CORE_PEER_ADDRESS when you run the chaincode
matpasha
2016-08-02 07:49
Alright. Let me try that. Thanks in advance
matpasha
2016-08-02 07:54
@bgorman: Didnt work:slightly_frowning_face:
bgorman
2016-08-02 07:55
did it log that it was trying to connect to somewhere more useful than 0.0.0.0?

it looks LGTM and we have 2+2 but I dont see a “merge” type button
ghaskins

my assumption is because of the jenkins -1, but wanted to be sure I am not missing something
sheehan
2016-08-02 14:03
yeah, it’s because the build failed
ghaskins
2016-08-02 14:03
ok
ghaskins
2016-08-02 14:03
that makes sense
sheehan
2016-08-02 14:04
I believe you can log into Jenkins with the same credentials you use for Gerrit and restart the build
ghaskins
2016-08-02 14:04
i’ve only merged 1-2 other gerrit patches so I wasnt sure if I was just confused
sheehan
2016-08-02 14:04
I saw @grapebaba say that in a comment, but I haven’t tried restarting a build myself
ghaskins
2016-08-02 14:07
hmm, looks like all the builders are offline
ghaskins
2016-08-02 14:07
oh well, the patch is ready to go in once CI confirmation passes
ry
2016-08-02 16:31
ghaskins: the x86 builders are instantiated when you start the build
ghaskins
2016-08-02 16:31
oh, i tried to restart the build and thought it failed because there was nothing online
ghaskins
2016-08-02 16:31
i might have misinterpreted some other issue
ry
2016-08-02 16:32
looks like it worked (the one from about 90 minutes ago)
ghaskins
2016-08-02 16:32
ive used jenkins quite a bit in the past, but this setup is foreign to me
ghaskins
2016-08-02 16:32
heh, ok, must just be operator confusion then :wink:
ghaskins
2016-08-02 16:32
ok, cool, thanks for the heads up
ghaskins
2016-08-02 16:33
ill check the gerrit state and merge if applicable

I'm trying to perform REST queries against the `membersrvc` and it seems that no matter what I do I get mangled text back (`��`) and the log says bogus greeting: `2016/08/05 01:51:47 transport: http2Server.HandleStreams received bogus greeting from client: "GET /registrar/test_vp0 "`. I assume that I am required to log in some how but I cannot seem to figure out how. Is someone able to point me in the right direction/documentation please?

Hi all I have a problem about chaincode in a fail over scenario
If i have four VP with chaincode-example02 deployed (PBFT)
Then i stop the VP3 and run the invoke at VP0 . After that ,i restart the VP3 and run another invoke. I find that the VP3 can’t sync the block (hold the block height 3 but the VP0 increase to block height 5) what’s the problem?
Logs :.Replica 3 sending view-change, v:1, h:0, |C|:1, |P|:7, |Q|:7 Replica 1 received view-change from replica 3, v:1, h:0, |C|:1, |P|:7, |Q|:7. Replica 1 already has a view change message for view 1 from replica 3

simon
2016-08-05 13:16
do you use pbft or noops?
voodoo
2016-08-05 13:17
Block height could't increase yet at VP3(use pbft )
simon
2016-08-05 13:18
keep submitting invokes
voodoo
2016-08-05 13:21
I try to peer node stop and start ，again and again submit invoke 。Only the vp0 vp1 vp2 get correct value。The vp3 seems nothing happened
simon
2016-08-05 13:21
yes
simon
2016-08-05 13:21
that is expected
simon
2016-08-05 13:22
if you do pbft with n=4,f=1, one node will be a bit behind
voodoo
2016-08-05 13:24
You mean a time lag between four peers
simon
2016-08-05 13:24
the reason is this:
simon
2016-08-05 13:24
pbft with f=1 allows for one malicious node
voodoo
2016-08-05 13:24
How to force sync the state？
simon
2016-08-05 13:24
a malicious node could be one that is deliberately slow
simon
2016-08-05 13:25
so the network cannot wait for that one node to catch up
simon
2016-08-05 13:25
that node will be just a bit behind
simon
2016-08-05 13:25
if you run many transactions, you will not really notice it
voodoo
2016-08-05 13:27
ok ，i get your point 。
voodoo
2016-08-05 13:27
thx guy
simon
2016-08-05 13:27
there is an option to create periodic null requests
simon
2016-08-05 13:27
this is a way to have the node catch up, even if there are no other transactions taking place
voodoo
2016-08-05 13:28
which way i can test it
simon
2016-08-05 13:28
set the null request timeout in the pbft config.yaml
voodoo
2016-08-05 13:28
ok i will try it
simon
2016-08-05 13:28
but it really is just a workaround
simon
2016-08-05 13:28
with the new architecture we're working on, this will change
simon
2016-08-05 13:29
and nodes should catch up much more quickly
voodoo
2016-08-05 13:30
i'm looking forward to the new architecture

@pascalli: the easiest thing is to pass `CORE_PEER_ADDRESS` as an environment variable when you start the chaincode
pascalli
2016-08-08 12:59
ok thanks I will try this: os.Setenv("CORE_PEER_ADDRESS", "127.0.0.1:5000")
pascalli
2016-08-08 13:47
it works now with : os.Setenv("CORE_PEER_ADDRESS", "127.0.0.1:30303")

Hi there,
Do you know how/where to fetch information about the network of peers (it's running locally in Vagrant) to put them in a user-friendly dashboard?
For example : number of peers, number of transactions or blocks, number of invoke / query etc.
The goal here is to bring more visibility on the blockchain side of a project through a dedicated interface, to show people how it works backstage.
Thank you very much

@sajz you could fetch a lot of that info from the REST API: https://github.com/hyperledger/fabric/blob/f7d932108d1e339d3371b6e8e922d09ecf913e9a/docs/API/CoreAPI.md#rest-api
I've also seen a nice-looking "Hyperledger Explorer" dashboard floating around, can't find the code though: https://vimeo.com/174814785 @konradpabjan may be able to link to the code for the Explorer

Nice, thanks for the quick answer!

coming from http://hyperledger.org, there are no clear links to the fabric documentation. on the github page obviously no one will search anything after reading that it's abandoned. It's completely unclear how to do anything with fabric from the gerrit page, where there is a documentation link, but it leads elsewhere. I understand for those who are already in the loop gerrit is way better for the automation, and I have nothing against it, however I wish you could show me where should I click if I want to explore fabric APIs, and their documentation.
sajz
2016-08-09 09:19
You can try this link maybe
sajz
2016-08-09 09:20
Part 6
ashnur
2016-08-09 09:20
sajz, thanks, but maybe you misunderstand my point. I am curious where I can find that link if I am on the http://hyperledger.org main page.
sajz
2016-08-09 09:20
Ah that's very true, it took me a while to gather all the links
sajz
2016-08-09 09:20
Not very "user-friendly" for a beginner
ashnur
2016-08-09 09:21
i think that page, with all the docs and the protocol description should be one of the biggest largest link somewhere.
ashnur
2016-08-09 09:22
also, the search still doesn't work in it, so it's literally terrible, and one must question if it's even up to date.
sajz
2016-08-09 09:22
I have a doubt : on the blockchain nothing is deleted, but with the hyperledger protocol and with fabric, if I want to "update" a table of users, for example delete a user or modify an attribute (age or something), am I really "modifying" or "deleting" the data ? from a storage point of view what is happening ?
ashnur
2016-08-09 09:22
sajz have you heard of datomic?
sajz
2016-08-09 09:22
not at all
ashnur
2016-08-09 09:23
it's easier to understand the idea through that concept because it's not distributed :slightly_smiling_face:
ashnur
2016-08-09 09:23
at least that's how i think about it.
ashnur
2016-08-09 09:26
basically, I separate the low level part which you call "storage" from the conceptually important things that are stored. this way the storage is just a transaction log, but the filtered view on the top of it can be an arbitrarily complex database
ashnur
2016-08-09 09:26
so no, it doesn't get deleted, but you can hide it
ashnur
2016-08-09 09:27
and those who use an app, that uses the blockchain, doesn't have to deal with this problem at all
ashnur
2016-08-09 09:27
sry if i overexplained, i do that a lot :disappointed:
sajz
2016-08-09 09:51
No actually it's a (much clearer) confirmation of what I was thinking so thanks.
Now even if you have two layers, let's say a low level layer with the log of all tx and the high level layer with the data that is displayed, can you still keep a link between the two?
Say the user of the app ask for a temperature and he gets an answer.
That answer is stored high level in my chaincode table (if I am not mistaking?) and is displayed on the interface by the proper function I made.
Now can I know where the same information (temperature) is stored in the low level blockchain ? Can I find a "proof".
Can I find the block number or the specific transaction that corresponds to that Query ?
With timestamp and content.
ashnur
2016-08-09 09:51
ok, so the docs says this: "A transaction is always associated with a chaincode specification which defines the chaincode and the execution environment such as language and security context. Currently there is an implementation that uses Golang for writing chaincode. Other languages may be added in the future."
ashnur
2016-08-09 09:51
how to know what is required for chaincode to be implemented in another language? Go is causing me problems.
ashnur
2016-08-09 09:55
sajz: absolutely. even more, what I think might end up happening in a lot of cases that you don't actually store the information on the blockchain, just the proof of it. this way you don't have to share it. zero knowledge proofs take this to the extremes :slightly_smiling_face:.
sajz
2016-08-09 09:57
Right ! I am actually working on privacy mecanisms for healthcare (works for other fields too) so I agree with this view.
It's also a way to (try to) keep the size of the ledger reasonable
ashnur
2016-08-09 10:01
sajz
2016-08-09 10:01
The thing is do we have a way (dev tool like an API) to fetch this proof?
The only thing I found in Fabric is something called the logger.
I was thinking of a function that allows you to "search" the ledger with criterias like: which chaincode are you looking at or from which address (or certificate) was the tx issued etc
ashnur
2016-08-09 10:02
this is the segment that goes into this> 4.2.2 Expiration and revocation of certificates
ashnur
2016-08-09 10:09
i think on ethereum for example you can't even hide things because there is nothing similar to the membership services?
sajz
2016-08-09 10:10
No membership and no CA but you can hide with a boolean the information you want the smart contract to discard
ashnur
2016-08-09 10:10
oh, hackish :smile:
sajz
2016-08-09 10:12
Yep!

Does someone have a clear definition of what is SHIM ?
sajz
2016-08-09 11:29
After few hours, I found this, but still not very clear : https://godoc.org/github.com/hyperledger/fabric/core/chaincode/shim
"Package shim provides APIs for the chaincode to access its state variables, transaction context and call other chaincodes. "
So SHIM enables persistency of the data used by the CC?

I guess there are such unit tests in core/chaincode
cbf
2016-08-09 12:20
@ashnur: agree with the feedback on the accessibility of the docs etc…
cbf
2016-08-09 12:21
thanks - we’re working on making things more accessible
ashnur
2016-08-09 12:22
np, I know that the pace you are working on these things, it's probably a bit of juggling with resources to make every part of the repo consistent with each other
ashnur
2016-08-09 12:23
cbf: can you maybe give some information regarding my question about how up to date the documentation is? for example I would expect one docs for the v0.5 developer preview, and another for the master branch.
cbf
2016-08-09 12:23
the docs reflect master
ashnur
2016-08-09 12:24
i see, that's great too
cbf
2016-08-09 12:25
if you want to fork the v0.5-developer-preview branch you can generate the docs by getting an account and adding your fork to http://readthedocs.org
ashnur
2016-08-09 12:26
oh right, is there some way i could help you making the docs searchable, that's a big issue because it's not a single page
cbf
2016-08-09 12:26
as we get more mature in our processes, we’ll have versions of the docs pertinent to major releases
cbf
2016-08-09 12:26
I believe that the docs should be searchable
ashnur
2016-08-09 12:26
it definitely isn't and it never was :slightly_smiling_face:
ashnur
2016-08-09 12:27
well, never is a harsh word, but not in the past several weeks
ashnur
2016-08-09 12:28
well, i am wrong again, it somewhat works, but when I search it shows no results and i had to realize that i have to click "Projects" to see search result...
ashnur
2016-08-09 12:29
and the results do not contain enough information to be enough for judging if it's relevant or not, 4 words is nothing
ashnur
2016-08-09 12:31
and of course most of what is found is not related to hyperledger project at all..
cbf
2016-08-09 12:31
huh
cbf
2016-08-09 12:31
I just checked… seems to be readthedocs search isn’t functioning
ashnur
2016-08-09 12:32
ok, so we both see the same thing :slightly_smiling_face:.
cbf
2016-08-09 12:33
yes
cbf
2016-08-09 12:33
not good;-)
ashnur
2016-08-09 12:36
github was good because of this, because there one could search and see what is what. i am not yet familiar enough with gerrit to find the same things there too
cbf
2016-08-09 12:37

I've been trying to use the new code from gerrit, and have been getting the following error message when trying to turn on the peer, shortly followed by it exiting with status 2.
```# http://github.com/hyperledger/fabric/vendor/github.com/Sirupsen/logrus

The last few lines (directory not found) repeats four times. However this always popped up before the update to the new code, and never stopped the peer from operating, so I suspect the problem is on the first part of the error message, about repeated declarations.
Does anyone have any idea why this is happening, and how I can fix it?

Hi,

2016-08-09 16:11
what happen if I put an infinite loop inside an invoke method of a chaincode?
ashnur
2016-08-09 16:13
joseph: what do you expect it should happen?
joseph
2016-08-09 16:15
I wonder if there is an infinite loop inside an invoke method, it would never get an consensus?
ashnur
2016-08-09 16:17
depends on the consensus algorithm, but this would be called a non-cooperative peer which happens all the time in practice anyway. if the network is large enough, it will tolerate it.
muralisr
2016-08-09 16:18
@joseph: @ashnur in 0.5 release, execution is after consensus and chaincode is expected to be deterministic and halt.
muralisr
2016-08-09 16:19
I’d expect the execute to fail with timeout and not be included in the block
ashnur
2016-08-09 16:19
@muralisr: well, as I said, depends on the algorithm
muralisr
2016-08-09 16:19
right
ashnur
2016-08-09 16:19
i know that pbft gives consensus with 3f+1 honest peers
ashnur
2016-08-09 16:19
but I bet it's hard to actually implement it

2016-08-09 16:21
@muralisr: when will we get fabric next? :slightly_smiling_face:
joseph
2016-08-09 16:23

joseph
2016-08-09 16:25
and how long is time out in fabric now?

2016-08-09 16:25
I don’t know if a timeline has been drawn on the roadmap… it would depend on the community processes wouldnt it ?

Hello -- I have a peer discovery issue. The peers are reporting their internal Docker IPs (172.x.x.x) instead of their external IP addresses, so other peers are unable to connect e.g. here's the info a peer received about peer ID HL2:
```16:49:55.556 [peer] beforePeers -> DEBU 2b4f9 Received PeersMessage with Peers: peers:<ID:<name:"HL2" > address:"172.17.0.28:7051" type:VALIDATOR > peers:<ID:<name:"Cisco-hl3" > address:"172.17.0.2:7051" type:VALIDATOR >```
Anyone familiar with this particular issue?
rseeger
2016-08-09 17:04
i.e.
Peer1 starts up. Peer2 starts up pointing to Peer1's CORE_PEER_DISCOVERY_ROOTNODE external IP. Peer2 says "Hi, in case anyone asks, my IP is 172.17.41.1" (wrong). Peer3 starts up also pointing to Peer1's CORE_PEER_DISCOVERY_ROOTNODE external IP and asks for peers. Peer1 says it knows about Peer2 at 172.17.41.1. Peer3 tries to connect to Peer2 at that IP, but times out because that's an internal docker IP on a different machine.
cbf
2016-08-09 17:14
@rseeger: that seems like a bug
cbf
2016-08-09 17:20
@rseeger: any info you can add regarding your configuration, commit level etc would be appreciated
rseeger
2016-08-09 17:29
Sure, but it feels like a config issue. The peer just needs to be able to announce it's external IP so other remote peers can connect to it.
rseeger
2016-08-09 17:32
Someone must have built a network of >2 nodes where the peers are not all on the same machine. In the meantime, I'm RTFMing! :slightly_smiling_face:
rseeger
2016-08-09 17:38
I don't have a JIRA login, but the config is basically:
rseeger
2016-08-09 17:38
First peer is started with:
```docker run -d -it -e CORE_VM_ENDPOINT=http://172.17.42.1:2375 -e CORE_LOGGING_LEVEL=DEBUG -e CORE_PEER_ID=Cisco-PEER1 -e CORE_PEER_ADDRESSAUTODETECT=true -p 7051:7051 hyperledger/fabric-peer peer node start```
Then we start subsequent peers (on different machines) to point to the external IP of the first (let's say it's 10.20.30.40):
```docker run -d -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=PEER2 -e CORE_PEER_ADDRESSAUTODETECT=true -e CORE_PEER_DISCOVERY_ROOTNODE=10.20.30.40:7051 -e CORE_LOGGING_LEVEL=DEBUG -p 7051:7051 hyperledger/fabric-peer peer node start```
rseeger
2016-08-09 17:42
All the peers can talk to the first one (because the external IP is explicitly specified) but not each other (because they only announce their Docker IPs)
rseeger
2016-08-09 17:51
Just realized my LinuxFoundation ID works for JIRA (yay SSO!). I added the info to the issue....
rseeger
2016-08-09 18:39
core/peer/peer.go line 145 GetLocalP() returns first non-loopback IP address to determine peer address; if running within Docker this will be the Docker IP 172.x.x.x; looks like you can't run a network of remote Hyperledger peers if you launch the peers with Docker.

I think the solution would be to pass the host IP to the docker container (as -e argument), then modify GetLocaIP() to check for that first. The docker-ized peer would then announce the correct IP to the network. I could make a pull request for this if it the correct approach. Thoughts?

For the moment I'm just looking for a way to change the logging level for a chaincode I'm working on, but I figure having the entire list - if it exists - is probably a good idea.

simon
2016-08-16 11:22
what is composite block hash?
simon
2016-08-16 11:22
i think ideally the blockchain should be checked on each start
lynx
2016-08-16 11:51
I haven't found where it's called
lynx
2016-08-16 11:52
Composite hash - using of two hashes to link blocks. One hash allows to change block content, if you have a key for that hash
simon
2016-08-16 11:58
lynx: can you explain more?
lynx
2016-08-16 12:34
It's a chameleon hash, that have pair of keys (public, private) and two nonces. With public key you can check hash and with the private you can get hash collision, and than change the content of the block.
simon
2016-08-16 13:05

davisbroda
2016-08-16 13:32
ah. Thanks
davisbroda
2016-08-16 13:50
I've looked through the env variables, and as far as I can tell, the following environment variable `CORE_LOGGING_PEER=INFO` should set the logging level to info rather than debug, overriding the yaml file. However when I supply this with a chaincode, it still spits out a bunch of debug information. Am I using the wrong command, or can this variable only be properly set when starting the peer, and cannot be individually tweaked for a chaincode - for instance, to have one chaincode give debug info, while the other does not.

Is this true? That we are depricating REST API ?
So how are we going to interact with the fabric from outside ? ( say some java application wants to talk to fabric... )
hgabor
2016-08-17 07:05
@ashishkel: I do not know if it will be deprecated or not but one can use GRPC (from Java, easily) and the SDK
ashishkel
2016-08-17 07:06
oh is that so.. then i m relieved.. I was just worried about the interfacing part.. Let me look up a bit on the gRPC.
hgabor
2016-08-17 07:10
@ashishkel: as I know - anyone, please correct me - there are two 'usable' grpc apis: devops (it will be deprecated) and "Peer API"
baohua
2016-08-17 09:09
although grpc is fast, but maybe we should remain the restful api, which is more popular today. Many legacy components still need a rest api.

I have no intent to remove it :slightly_smiling_face:

@hgabor: Okay. Lets hope we keep Rest alongside anyways. :pray::skin-tone-3:
garisingh
2016-08-17 10:52
@ashishkel: my opinion on the REST interface is that "peer" nodes should only implement / expose operations about the network, statistics, etc. We should then have a standalone REST server / implementation which is built on top of the SDK.
garisingh
2016-08-17 10:52
This way, you'd have the ability to provided whatever security integrations are required for the REST API without us having to pollute the peer code with an infinite number of options
garisingh
2016-08-17 10:53
this will be much cleaner in the long run
ashishkel
2016-08-17 10:56
@garisingh: there are two types of peer code rite? System chain code and the user chaincode. When u said polluting the peer code with unnecessary options, u meant the System chain code part ?
simon
2016-08-17 10:56
what's the deal with "ChaincodeInvocationSpecification" etc?
simon
2016-08-17 10:56
why do we have this?
simon
2016-08-17 10:56
why not directly a Transaction?
ashishkel
2016-08-17 11:00
@garisingh: and what I understood is, the user chaincode level operations ( init/invoke/query) are going to be routed through the new REST server . And anything which u want to query directly on the peer - ( its own statistcs. health etc ) you would expose as REST API directed against the peer.
ashishkel
2016-08-17 11:01
in that case where are we goin to run this REST server ? along with Peer itself?
garisingh
2016-08-17 11:13
think of the REST server as being like a "proxy" client for your applications. So for example instead of integrating the SDK with all of your applications, you deploy the REST server within your environment and then have your apps communicate with it instead of going directly to the Peer(s) via GRPC
garisingh
2016-08-17 11:14
so you could technically run it anywhere that can connect to the peer
simon
2016-08-17 11:16
i don't quite understand what the SDK does
simon
2016-08-17 11:16
and why it is in node.js
simon
2016-08-17 11:17
let's say i have my existing system written in java
simon
2016-08-17 11:17
do i have to run the node.js SDK stuff somewhere, and my system talks to the SDK?
simon
2016-08-17 11:17
or would i talk directly to the peers?
ashishkel
2016-08-17 11:20
@garisingh: that sounds fair.
ashishkel
2016-08-17 11:21
but as simon was asking, this SDK is based on Node.js alone?
ashishkel
2016-08-17 11:24
as far as my current mental picture of an SDK goes, its a blackbox, which talks to me in CLI/REST & Some Node.js code
ashishkel
2016-08-17 11:24
I have made hands dirty with CLI nd Restful side. but node.js has been left alone till now.
ashishkel
2016-08-17 11:25
and the client program we have uses the Restful handle to interact with the Fabric now.
ashishkel
2016-08-17 11:27
So with gari's approach, the only thing which changes is , I m not goin to talk to my peer for any chaincode ( user chaincode) stuff anymore *unless* i need to know some specific things which a physical peer can only tell.
ashishkel
2016-08-17 11:27
is this understanding correct?
garisingh
2016-08-17 11:29
yeah - instead of the REST endpoint being the peer for transactions, it would be to this mythical REST server I'd like to see us build
garisingh
2016-08-17 11:30
at this point, I really waiting to do this for the V.next architecture.

whatever language the sdk is implemented based on. would like to suggest keeping it simple and stateless, by only take advantages of fabric functionalities, instead of having additional black code. This can also help decouple, and support new architecture.

Hi, i would like to use logger in my chaincode, to display logs in the stderr console like peer or shim. I use a vagrant VM, I use the following command to start my node: ./peer node start --loggin-level=info, and I use the following code in my chaincode:
var logger = shim.NewLogger("mychaincode")
main:
logger.SetLevel(shim.LogInfo)
logLevel, _ := shim.LogLevel(os.Getenv("SHIM_LOGGING_LEVEL"))
shim.SetLoggingLevel(logLevel)
but I haven't logs from my chaincode in the console!
is somebody can help me ?
thanks

@pascalli the chaincodes run in their own docker containers, named something like <network>-<peer>-<chaincodeID>, try looking in there for your logs with `docker logs <containerID>`

@joseph the result is hex-encoded.
tx.on('complete', function (results) {
console.log('Results:[%j]', new Buffer(results,'hex').toString());

Hi, I use a table in my chaincode, | A |B |C | D |...where A, B , C, and D are keys. So I would like use the getrows methods with the follows parameters:
getRows(args[D])
getRows(args[A])
getRows(args[B][D])
getRows(args[C][D])
do you know the syntaxe to used ?

@pascalli: It’s not possible today. The partial key queries supported would be
A
A | B
A | B | C
A | B | C | D
Currently, focus is on improving the query capability in the next architecture. If you have specific requirements, it would be great to open an issue at http://jira.hyperledger.org

Hi All, I am trying to install hyperledger fabric in my local machine using the docker method (option 2 - http://169.53.62.117/site/Setup/Chaincode-setup/#running-the-cli-or-rest-api). I am able to run the peer, CA. I was successful in starting and registering the chain code. I need help to ssh into the docker container that is running the peer and test the Rest API to deploy the example chain code. Thank you in advance for your help!
muralisr
2016-08-19 15:03
@vijayr24:_ I was successful in starting and registering the chain code._ … sounds like you have already “deployed” the chaincode ?
muralisr
2016-08-19 15:05
how is that different from _(I want to) test the Rest API to deploy the example chain code_
cbf
2016-08-19 15:06
you should be able to use Swagger or Postman etc to access the REST API
cbf
2016-08-19 15:07
as for chaincode, if you are running in —peer-chaincodedev mode, and you start your chaincode directly, it does not need to be “deployed” by the REST API because it self-deploys on start-up
cbf
2016-08-19 15:07
you can just start invoking
ghaskins
2016-08-19 15:14
@cbf unless something changed, note that you still do need to “deploy” devmode to set the ctor args
ghaskins
2016-08-19 15:14
the chaincode app starts up in a quasi paused state until you complete the deploy
ghaskins
2016-08-19 15:15
calling it “deploy” is a bit of a misnomer, but hey
ghaskins
2016-08-19 15:15
:wink:
cbf
2016-08-19 15:16
sigh - then the docs suck
cbf
2016-08-19 15:16
because that is not what they say
muralisr
2016-08-19 15:20
in any case _I think shouldn’t need to ssh into the peer to do things. I suspect @vijayr24 is attempt to use CLI (for which you do need to be on the peer). To reiterate @cbf’s suggestion REST API from outside the peer would be the way to go
kletkeman
2016-08-19 15:47
@vijayr24 @cbf @muralisr @ghaskins
The docs are rather densely packed since the sandbox doc became the chaincode_setup doc and combined three different methods of setting up for debugging. But the docs do seem to be pretty accurate.
I have had no trouble working with a single peer in dev mode and my chaincodes in dev mode as well. The deploy command is necessary to call your Init, and it should be the first message you send after starting up the chaincode, else it will be ignored. I find, though, that if your container's database has been initialized, you can restart at will and just carry on without the deploy. Everything works as expected. I have also implemented a "clearWorldState" function that I find incredibly handy so that I can start again with a deploy etc ...
Working with POSTMAN using REST works perfectly fine as well. For a fairly well featured IoT sample with related POSTMAN scripts and environments, take a look at the sdk folder linked below. There are docs to go with it. It is far from perfect, but it is an exploration of ways in which Hyperledger can be used for IoT contracts with a single tracked asset and multiple devices reporting on it. It tries to avoid API proliferation using a pattern I came up with called "partial state as event" ... I am working on the more advanced form with multiple related assets and multiple event functions, but that will not be ready for a few weeks as I am on vacation right now.

Hi,
We can listen to the submitted, complete and error events from the client SDK but for instance the 'complete' event is just 'waited for 5 seconds and assumed it was completed'. So a few questions come up:
1) Is there work being done on making these events more real?
2) Are there more events we can listen to?
3) Can we already fire events from the chaincode?
4) Can we listen to events from the chaincode?
Thanks!
ghaskins
2016-08-20 12:03
@arner: that's all under active development. The fabric side was merged this week and the SDK side should follow shortly
arner
2016-08-20 12:04
That's great news. Could you elaborate a little bit on which parts are (more or less) ready?
ghaskins
2016-08-20 12:08
That was merged this past week. I know Patrick is also working on the SDK side
ghaskins
2016-08-20 12:09
IIUC this would be primarily WRT system type events, like blocks and transactions
ghaskins
2016-08-20 12:09
Chaincode events might be further out, not sure
ghaskins
2016-08-20 12:10
I'd defer to @muralisr and @pmullaney for details
ghaskins
2016-08-20 12:11
I'm guessing you are probably not using chaintool, but @ecblseg is adding support to the chaintool CCI schema to describe custom events for chaincode
arner
2016-08-20 12:15
Alright, thanks a lot. We're indeed not using chaintool, just looking for a way to handle events in a nice way from a NodeJS web application. The eventing system will bring about a massive improvement in terms of user experience (if we can use web sockets for instance)

muralisr
2016-08-21 23:07
sure thing
zaki
2016-08-21 23:12
I figured out something that worked for me.
The root cause is there was an unvendored dependency
I used a bunch of tools like govendor that promise to check if your build is properly vendored
What ended up surfacing the error was changing to a free `$GOPATH` directory, copying in my chaincode and then running `go install [path to chaincode]`
muralisr
2016-08-21 23:39
which explicitly showed what the error was as you don’t resolve the dependency thru the vendored packag

@warm3snow It looks like you are trying to query the GRPC port, not the REST port. Try `CORE_PEER_ADDRESS=172.17.0.4:5000` (note that the port should be 7050 if you are using the latest code, but it looks like you aren't)
warm3snow
2016-08-22 05:34
@jcarrivick I tried the CORE_PEER_ADDRESS=172.17.0.4:5000, but I got an error:
Error: Error building chaincode: Error trying to connect to local peer: grpc: timed out trying to connect
I think "CORE_PEER_ADDRESS=172.17.0.4:30303" is correct, and the query result may be encrypted. I just want to know how to get the plaintext of it
Thanks anyway
jcarrivick
2016-08-22 05:37
The fact you got a plain text response to your request on port 5000 indicates you have successfully queried the REST server. The error tells you more. It seems that the chaincode you deployed was not able to build because it was not able to communicate properly.

Hmm that seems to look OK. I've never used `CORE_VM_ENDPOINT` as the unix socket before, I've always set it to `CORE_VM_ENDPOINT=http://172.17.0.1:2375` in `environment`
jcarrivick
2016-08-22 05:58
can you give that a shot?

Hi jcarrivick i took latest from github not working
jcarrivick
2016-08-22 06:39
We're in a bit of a funny situation at the moment, the development code base has moved to gerrit: https://gerrit.hyperledger.org/r/#/admin/projects/fabric which means Github is out of date
jcarrivick
2016-08-22 06:40
The plan I think is to get github to mirror gerrit at some point, but it hasn't got there yet
jcarrivick
2016-08-22 06:41
So you will need to pull the latest code from Gerrit rather than github for now

Hi, when we used the query method, is that write a trace in a transaction on the block?
as can be seen for example by querying the API with ../chain/blocks/'block_number'
because I have only traces concerning deploy or invoke methods, but nothing for query method.
thanks
yacovm
2016-08-22 13:40
can you copy a line example of a trace for invoke or deploy? It might be a module that a query doesn't reach it

Hello all, I am trying to run asset management example code for hyperledger/fabric. when i run the asset management application code i am facing some error.
Error : sending init failed(handler not found for chaincode bbf06fd3705f348f759199e5fa42f158b36fd39e46ac1407196ebecf990676cec6c5578d1febafe5256741a7a4bad5b625a664355d0da62bd04f91541a5fa94b)
i am using vagrant setup for running asset management code.Can anyone help me with this issue
muralisr
2016-08-23 11:44
@balakrishna: likely the deploy failed. What mode are you running peer in (in “—peer-chaincodedev” mode) ?
balakrishna
2016-08-23 11:46
yes. “—peer-chaincodedev” mode
balakrishna
2016-08-23 11:48
@muralisr yes. “—peer-chaincodedev” mode
balakrishna
2016-08-23 11:49
@muralisr i am running with 1 membersrvc and 1 peer node
muralisr
2016-08-23 11:51
ok
muralisr
2016-08-23 11:52
can you paste your chaincode exec line ?
muralisr
2016-08-23 11:54
if you are using CORE_CHAINCODE_ID_NAME=mycc
muralisr
2016-08-23 11:55
make sure you are passing “mycc” as name for deploy, invoke query (from CLI that would be “-n mycc”)
balakrishna
2016-08-23 12:36
i using app provided by asset manager example.
balakrishna
2016-08-23 12:37
@muralisr Here is the link : https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management/app
balakrishna
2016-08-23 12:38
this the application i am running to execute asset management example.
muralisr
2016-08-23 12:40
so you are running something like ` CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=127.0.0.1:7051” ./app ?`
balakrishna
2016-08-23 13:20
@muralisr just running "./app" command
muralisr
2016-08-23 13:20
try adding CORE_CHAINCODE_ID_NAME=mycc

2016-08-23 13:21
and using “mycc” as the name of the chaincode in query invokes etc

Have anyone got idea how to deploy the fabric on a virtual machine of DigitalOcean or AWS?
wangbin767
2016-08-24 06:11
It seems the vagrant can only run on a physic machine
ccooper21
2016-08-24 06:14
I'm not sure if it would be a wise idea, but from past experience I believe that Digital Ocean supports nested virtualization. So it should be possible to run Vagrant within one of their VMs. AWS does not support this last time I checked.
ccooper21
2016-08-24 06:24
another possibility is to target Vagrant against something other than VirtualBox by editing "Vagrantfile". I think Vagrant supports EC2 as an example. You'd have to some how migrate the base Virtualbox Hyperledger disk image to an AMI on your own first though I suppose.

Hi, I'm using Vagrant installation, when I use a "query" method on my chaincode, I have a response, but if after this request I use the API (/blocks/'block nb' ) I haven't information concerning this 'query' is it normal ? because if I use an invoke 'method' I have this information.
thanks
Pascal
hgabor
2016-08-24 08:21
@pascalli do you mean tha t queries are not in the ledger?
pascalli
2016-08-24 08:23
I don't know, but if I request the API /127.0.0.1:5000/blocks/'block nb' I have no information concerning the query transaction, is it norma, a bug or an installation problem ?
hgabor
2016-08-24 08:24
what is block nb?
hgabor
2016-08-24 08:24
block number
hgabor
2016-08-24 08:24
okay so blocks are the parts of the ledger
hgabor
2016-08-24 08:25
ledger is made of blocks, in other words
hgabor
2016-08-24 08:25
but your query is not present in the last block (ot in some other)
hgabor
2016-08-24 08:26
so it is not in the ledger. and yes, this is normal. queries are just queries, as far as I know they are not persisted
pascalli
2016-08-24 08:26
yes not present in the last block, and if I verify all blocks, I have only 'deploy' and 'invoke' methods
hgabor
2016-08-24 08:26
that's the way it works :slightly_smiling_face:
pascalli
2016-08-24 08:27
so, we haven't information in the ledger concerning 'query methods' ?
pascalli
2016-08-24 08:30
ok , thanks for this info :slightly_smiling_face: but how can we check if a query worked well?

hi ... just noticed that the usage FAQ (https://github.com/hyperledger/fabric/blob/master/docs/FAQ/usage_FAQ.md) retains the notion from the protocol spec that NV nodes maintain a full copy of the ledger for local queries. This would of course require both the chain and world state.
My question is whether this has been implemented recently, or is a misstatement as it was the last time I had this discussion on one of the hyperledger channels? Thanks.

heads up everyone. As noted on the mailing list, we will be archiving the existing GH fabric and fabric-api repositories and replacing them with mirrors of Gerrit. Hence, we will be transferring the fabric and fabric-api repository and all the corresponding issues and pull requests to the hyperledger-archives org on GH and replacing this repository with a read-only mirror of our Gerrit source. As a result, any automatic GH redirects will be broken. If you haven't already migrated your PR to Gerrit, and intend to do so, you will need to change your git remote to reference the transferred repository (e.g. git@github.com:hyperledger-archives/fabric) on your local clone.

And of course when Docker exhibits serioud security hole, I need to upgrade. I latter case, I'll modify the code for v0.5 or pull latest source.

garisingh
2016-08-26 10:48
@venkat - when using REST, the source for your chaincode needs to be available on the file system and accessible by every peer to which it will be deployed (it would also need to be in the location set by the GOPATH where each peer is running). If you are OK with having your chaincode source stored in a public Github repo, then you don't have to worry about the previous comment as long as the machine where your peer(s) is have access to the internet
venkat
2016-08-26 11:01
@garisingh - I was trying to deploy example02 from the fabric repo (public). In this case why do I run into this error? Yes. the peers have the fast internet connection.
venkat
2016-08-26 11:23
@garisingh - Sorry, I couldn't understand your first comment. How does the chaincode gets into peer in the first place? Doesn't the peer download it?
venkat
2016-08-26 11:27
Also I don't see this requirement in the docs for chaincode developer. Am I missing something?
venkat
2016-08-26 11:29
Also, why can't the dev and deploy of chaincode pretty simple and straight forward for newbies? Does this have to be so hard?
garisingh
2016-08-26 11:57
you can disregard my first comment in this case. the error you are seeing comes from the inability of the peer to download the chaincode source from github
garisingh
2016-08-26 11:58

or that the Docker socket was not mounted to the container

right. and there’s also the “mycc” in the logs. So looked like a few things mixed up
garisingh
2016-08-27 13:09
yeah - true. so if trying to run in dev mode, then the answer is easier - need to start up the chaincode process manually. If not, then need to properly mount the socket and/or use the TCP endpoint of the Docker daemon

@muralisr - here is the docker-compose file I'm using:

2016-08-27 15:08
First I'm doing a vagrant up from devenv folder of fabric soruce code
venkat
2016-08-27 15:08
Then I do vagrant ssh and then run docker-compose up from inside the vagrant terminal.
muralisr
2016-08-27 15:08
@venkat as @garisingh pointed out, first problem is that your docker is root of the issue
muralisr
2016-08-27 15:09
CORE_VM_ENDPOINT=unix:///var/run/docker.sock is not working
muralisr
2016-08-27 15:12
what does ps -ef | grep docker show ?
venkat
2016-08-27 15:25
@muralisr - it is true that there is no /var/run/docker.sock file. But I'm pretty sure that the docker daemon is running. Also, should that affect the finding of the handler fo chaincode while sending init?
muralisr
2016-08-27 15:27
the chaincode contacts the peer first and registers with it. If the chaincode did not register - because it couldn’t talk to the peers port - then I’d exepect the send init call to fail as well
venkat
2016-08-27 15:27
@venkat uploaded a file: https://hyperledgerproject.slack.com/files/venkat/F25KLPSQH/ps_-ef___grep_docker.txt
muralisr
2016-08-27 15:28
is the above from vagrant ?
muralisr
2016-08-27 15:29
looks like its from the mac host...
venkat
2016-08-27 15:30
sorry - here is from inside vagrant
venkat

@venkat uploaded a file: https://hyperledgerproject.slack.com/files/venkat/F25KTD22E/-.txt
venkat
2016-08-27 15:32
basically the error is is same whether I run the peers from inside vagrant or outside of it.
muralisr
2016-08-27 15:37
ok
muralisr
2016-08-27 15:38
how do you run the chaincode ?
venkat
2016-08-27 15:40
trying to deploy example02 through REST (swagger ui)
muralisr
2016-08-27 15:40
ok
venkat
2016-08-27 15:40
REST UI shows no errors - 200 OK
muralisr
2016-08-27 15:44
a few points : (1) in —peer-chaincodedev mode, you have to run the chaincode yourself in another window (2) you still have to do the “deploy” though… so as to call the “init” method and (3)deploy returns 200 as it just “submits” the request, the execution itself is asynchronous … ie, the 200 just says the “submit” was successful
muralisr
2016-08-27 15:44
finally, you don’t have to run the peer in docker at all… though we can and should get to the bottom of your problem
muralisr
2016-08-27 15:45
if you have not already done that, we can try and get you started without running the peer via compose
venkat
2016-08-27 15:46
Sure -
venkat
2016-08-27 15:46
Shuould I run peer in non-de mode from fabric/peer folder?
muralisr
2016-08-27 15:46
yes please
muralisr
2016-08-27 15:46
as in
muralisr
2016-08-27 15:46
./peer node start —peer-chaincodedev
venkat
2016-08-27 15:47
Ok
muralisr
2016-08-27 15:47
I like the “./peer” as I can just do “go build” and pick up any changes I might have made
muralisr
2016-08-27 15:48
then in a second wind
muralisr
2016-08-27 15:48
window
muralisr
2016-08-27 15:48
cd $GOPATH/src/github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02
venkat
2016-08-27 15:48
start peer in NON-dev mode?
muralisr
2016-08-27 15:48
go build
muralisr
2016-08-27 15:49
lets first try the dev mode (with the —peer-chaincodedev option)
venkat
2016-08-27 15:49
ok
muralisr
2016-08-27 15:53
so in the second window, go build
venkat
2016-08-27 15:53
we need a member srvc as well?
muralisr
2016-08-27 15:54
not necessary if security is disabled
venkat
2016-08-27 15:54
ok
muralisr
2016-08-27 15:54
which by default, is
venkat
2016-08-27 15:54
I ran go build in the example02
muralisr
2016-08-27 15:54
ok
venkat
2016-08-27 15:54
and got a 14 MB file
muralisr
2016-08-27 15:54
ok
muralisr
2016-08-27 15:54
can you do netstat -an | grep LISTEN ?
muralisr
2016-08-27 15:55
want the port peer is listening on
venkat
2016-08-27 15:55
yep - did it
venkat
2016-08-27 15:56
@venkat uploaded a file: https://hyperledgerproject.slack.com/files/venkat/F25KNNCBZ/-.txt
muralisr
2016-08-27 15:59
ok 7051
muralisr
2016-08-27 16:00
is your docker compose still running ?
muralisr
2016-08-27 16:00
likely not
muralisr
2016-08-27 16:00
so
muralisr
2016-08-27 16:01
CORE_PEER_ADDRESS=127.0.0.1:7051 CORE_CHAINCODE_ID_NAME=mycc ./chaincode_example02
muralisr
2016-08-27 16:01
you should see some logs that indicated chaincode has registered
muralisr
2016-08-27 16:03
in a third window you can do `./peer chaincode deploy -n mycc -c ‘{Args: [“init”,”a”,”100”,”b”,”100”]}’`
venkat
2016-08-27 16:03
nope - no docker-compose running
muralisr
2016-08-27 16:03
ok
venkat
2016-08-27 16:04
the chaincode is ready adn listening
venkat
2016-08-27 16:04
16:03:07.932 [shim] DEBU : Received REGISTERED, ready for invocations
muralisr
2016-08-27 16:04
ok. ` ./peer chaincode invoke -n mycc -c '{Args: [“invoke”,”a”,"b","10"]}’`
muralisr
2016-08-27 16:05
but do the deploy first
muralisr
2016-08-27 16:05
and finally
muralisr
2016-08-27 16:06
`./peer chaincode query -n mycc -c '{Args: [“query","a"]}’`
venkat
2016-08-27 16:06
Chaincode argument error: invalid character 'A' looking for beginning of object key string
venkat
2016-08-27 16:07
base64 issue?
venkat
2016-08-27 16:09
ok - ran the deploy after base64 onversion

@venkat you are missing quotes for Args ./peer chaincode query -n mycc -c '{"Args": ["query","a"]}'
pvishnum
2016-08-27 16:19
you can just redeploy the chaincode

"handler not found" is the error I always run into - even while using REST.
muralisr
2016-08-27 16:22
only thing I can think of… typo in CORE_CHAINCODE_ID_NAME
muralisr
2016-08-27 16:22
give me a few
muralisr
2016-08-27 16:22
let me make sure it works in my env
muralisr
2016-08-27 16:26
so the following worked on my machine:
muralisr
2016-08-27 16:26
./peer node start --peer-chaincodedev
muralisr
2016-08-27 16:26
CORE_PEER_ADDRESS=127.0.0.1:7051 CORE_CHAINCODE_ID_NAME=mycc ./chaincode_example02
muralisr
2016-08-27 16:27
./peer chaincode deploy -n mycc -c '{"Args": ["init","a","100","b","200"]}'
muralisr
2016-08-27 16:28
./peer chaincode invoke -n mycc -c '{"Args": ["invoke","a","b","10"]}'
muralisr
2016-08-27 16:28
./peer chaincode query -n mycc -c '{"Args": ["query","a"]}'
venkat
2016-08-27 16:28
your peer docker image date?
venkat
2016-08-27 16:29
well - that shouldn't matter
muralisr
2016-08-27 16:29
not sure if you have seen this : http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#option-1-vagrant-development-environment
muralisr
2016-08-27 16:30
“Option 1” is pretty much the above if you ignore the “security” options
venkat
2016-08-27 16:31
may be I'll do a vagrant destroy and foloow the steps again. But my main concern is not the command line stuff.
muralisr
2016-08-27 16:31
there have been recent changes to the API and the doc should get updated … for instance it still has “function"
muralisr
2016-08-27 16:31
right
venkat
2016-08-27 16:31
I need REST to be working
muralisr
2016-08-27 16:31
ok
muralisr
2016-08-27 16:31
let me check what I do for REST
venkat
2016-08-27 16:33
I didn't understand what happens with REST - does the peer download the source code for the chaincode from github (in case pblic repo)?
muralisr
2016-08-27 16:35
functionally REST and the CLI are equivalent functionally .. so no difference
muralisr
2016-08-27 16:35
_download the source code for the chaincode from github (in case pblic repo)_ can be done both from CLI and REST
venkat
2016-08-27 16:36
But in case of command line we "ran" the example02 - for registering etc. Does this happen with REST too?
venkat
2016-08-27 16:37
and the chaincode was listening
muralisr
2016-08-27 16:37
the reason for some of the issues you had was because of this usage - "https://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02"
muralisr
2016-08-27 16:39
the peer sees that "http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02” resolves to identical local package and so will not “download” from the public https:// repo
venkat
2016-08-27 16:39
Ok .
muralisr
2016-08-27 16:39
_But in case of command line we "ran" the example02 - for registering etc. Does this happen with REST too?_ …. yes, in “peer-chaincodedev” mode you can use REST (as opposed to CLI)… although there were some errors in REST due to recent changes. Not sure if they have been fixed. If not they should be fixed soon
muralisr
2016-08-27 16:41
now
muralisr
2016-08-27 16:41
if you like we can try without dev mode
muralisr
2016-08-27 16:41
./peer node start
venkat
2016-08-27 16:42
I tried that earlier and posted about errors here. May be I should do vagrant destroy first.
muralisr
2016-08-27 16:42
well
muralisr
2016-08-27 16:43
lets try this first ? I think likely it was not vagrant (but you could be right)
venkat
2016-08-27 16:43
ok - lets go ahead
muralisr
2016-08-27 16:43
let me run in my env and copy past
venkat
2016-08-27 16:46
started with
./peer node start
muralisr
2016-08-27 16:48
CORE_LOGGING_LEVEL=debug ./peer chaincode deploy -p http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 -c '{"Args": ["init","a","100","b","200"]}'
muralisr
2016-08-27 16:48
it will dump out a long hex ID
venkat
2016-08-27 16:48
first run this ? -
venkat
2016-08-27 16:48
CORE_PEER_ADDRESS=127.0.0.1:7051 CORE_CHAINCODE_ID_NAME=mycc ./chaincode_example02
muralisr
2016-08-27 16:49
nope… that’s needed only in -peer-chaincodedev moe
venkat
2016-08-27 16:49
got it
muralisr
2016-08-27 16:49
ok
muralisr
2016-08-27 16:51
use the dumped out id as the “-n” param in invoke and query
muralisr
2016-08-27 16:51
CORE_LOGGING_LEVEL=debug ./peer chaincode invoke -n df367164cdae32dfd794d41cecb877d5617e234434c76161acdbce78b3b758240336948d84e91e53ae36afca0266690ab1cdbdcd2778ef66ffca6f5982148d45 -c '{"Args": ["invoke","a","b","10"]}'
venkat
2016-08-27 16:51
for the chaincode spec is asking for Function parameter. So added it
muralisr
2016-08-27 16:51
really ?
muralisr
2016-08-27 16:51
ok
muralisr
2016-08-27 16:52
then maybe you are a few levels back
venkat
2016-08-27 16:52
@venkat uploaded a file: https://hyperledgerproject.slack.com/files/venkat/F25KW68L9/-.txt
muralisr
2016-08-27 16:53
try without the “init” in "Args"
venkat
2016-08-27 16:53
ok - will try again
venkat
2016-08-27 16:53
yep
muralisr
2016-08-27 16:53
the recent changes remove “Function” let user specify differentiation via Args
venkat
2016-08-27 16:54
the peer binary that I'm using could be a week old
muralisr
2016-08-27 16:54
ok
venkat
2016-08-27 16:54
but docker images are latest
muralisr
2016-08-27 16:54
ok
venkat
2016-08-27 16:54
looks ike all good

muralisr
2016-08-27 16:59
btw, if the deploy was successfully executed `docker ps` should show the chaincode container running
venkat
2016-08-27 16:59
invoke is going fine
venkat
2016-08-27 16:59
@venkat uploaded a file: https://hyperledgerproject.slack.com/files/venkat/F25KH7T0U/-.txt
muralisr
2016-08-27 16:59
proof of the pudding is the query
muralisr
2016-08-27 17:00
as invoke is also a submission (ie, asynch)
muralisr
2016-08-27 17:00
query is synchronous
venkat
2016-08-27 17:01
@venkat uploaded a file: https://hyperledgerproject.slack.com/files/venkat/F25KHEGQ4/-.txt
muralisr
2016-08-27 17:02
there you go :slightly_smiling_face:
muralisr
2016-08-27 17:02
so the invoke query etc could also be done equivalently in REST
venkat
2016-08-27 17:02
ok - trying swagger
muralisr
2016-08-27 17:03
although I thought REST is being fixed in latest
muralisr
2016-08-27 17:03
but perhaps will work in your level
venkat
2016-08-27 17:04
deploy is the only problem for me- my chaincode source is in a github repo - and we want our testing team to deploy through REST
venkat
2016-08-27 17:05
without having to deal with building fabric code etc
muralisr
2016-08-27 17:05
so
muralisr
2016-08-27 17:06
you can deploy from a public repo successfully (with CLI even)
muralisr
2016-08-27 17:06
is that github repo public ?
muralisr
2016-08-27 17:07
the other option is to use the SDK
venkat
2016-08-27 17:07
I will try deploying REST on the NON-dev peer
muralisr
2016-08-27 17:07
ok
venkat
2016-08-27 17:07
because it worked from commandline
muralisr
2016-08-27 17:09
ok
venkat
2016-08-27 17:12
deploy work from REST too - but I believe it is because I'm using older version of peer binary
venkat
2016-08-27 17:13
If I use docker images, then none of this works
muralisr
2016-08-27 17:21
it should work too …in theory
muralisr
2016-08-27 17:24
the key would be to get the ip address to communicate with the peer’s container
muralisr
2016-08-27 17:24
using docker inspect
muralisr
2016-08-27 17:25
and using that
venkat
2016-08-27 17:26
in case of docker, i guess the example package doesn't already exist locally
muralisr
2016-08-27 17:26
it will be in the peer
muralisr
2016-08-27 17:27
are you using the above compose file to run the peer ?
venkat
2016-08-27 17:27
right
muralisr
2016-08-27 17:27
ok
muralisr
2016-08-27 17:27
give me a few
venkat
2016-08-27 17:27
what if the chaincode is outside the fabric source code? It won't be available in the peer image.
venkat
2016-08-27 17:43
And why should the example chaincodes be bundled with peer images?
muralisr
2016-08-27 17:49
chaincode does not have to be in the fabric… the examples are bundled in the fabric
muralisr
2016-08-27 17:49
not sure if you have used the SDK but that allows you provide chaincode from outside of the peer
muralisr
2016-08-27 17:49
also this area is evolving and will get better
muralisr
2016-08-27 17:50
so with the compose..
muralisr
2016-08-27 17:51
docker-compose -f `compo` up --force-recreate where `compo` is

you are using peer binary from command line, to deploy. Can you use REST, instead
venkat

ah - may be I should have started docker peer in non-dev mode
muralisr

you can use rest too

sorry missed your comment -about peer not ahving access to docker.sock
venkat
2016-08-28 11:58
if so, how can th peer start a container for th chaincode?
garisingh
2016-08-28 12:04
there are 2 ways -
1) configure the Docker daemon on the host to listen on TCP, e.g. start the Docker daemon and pass in `-H ` then configure `CORE_VM_ENDPOINT=http://172.17.0.1:2375` (assuming that that's the address for docker0)
garisingh
2016-08-28 12:04
other option is to mount the socket as a volume:
```
vp0:
image: hyperledger/fabric-peer
ports:
- "7050:7050"
- "7051:7051"
- "7052:7052"
environment:
- CORE_PEER_ADDRESSAUTODETECT=true
- CORE_VM_ENDPOINT=unix:///var/run/docker.sock
- CORE_LOGGING_LEVEL=DEBUG
- CORE_PEER_ID=vp0
volumes:
- /var/run/docker.sock:/var/run/docker.sock
command: sh -c "sleep 5; peer node start"
```

2016-08-29 05:19
I think 7051 is for REST API.
This variable is for gRPC, which is by default, setting the port to 30303
CORE_PEER_ADDRESS=128.107.21.212:30303
CORE_PEER_DISCOVERY_ROOTNODE=128.107.21.204:30303
will work.
But if you need to change the port of gRPC, you need to change this together
CORE_PEER_PORT=30303
CORE_PEER_LISTENADDRESS=0.0.0.0:30303
In case if you need to change REST API port, you need this one instead,
CORE_REST_ADDRESS=0.0.0.0:7051

well, one difference is that STL is python and fabric is (mostly) go
cbf
2016-08-29 12:51
we have different models for dealing with “smart contracts”
cbf
2016-08-29 12:51
and STL has a very pluggable consensus model as it was (I believe) written with an original objective of enabling rapid experimentation with different consensus models
cbf
2016-08-29 12:52
fabric also has a primary focus of enabling “permissioned” blockchains - eg no mining, but closed network of members known to each other

race condition with chaincode?? what can I do to avoid tha?
garisingh
2016-08-29 16:52
in that case, chaincode was not properly deployed or deployment did not complete. Remember that a reply transaction is asynchronous. So until your chaincode containers are actually running, you'll get that error
garisingh
2016-08-29 16:53
you typically have to wait some period of time (depends on where you are running) between deploy and query.
venkat
2016-08-29 16:53
so - the chaincode contanier is not running or not ready ?

deploy and invoke are “submits” and the actual execution is asynchronous ( if you recall :slightly_smiling_face: …its easy to overlook till you get used to it)

oh - ok. But enough time has elapsed between deploy and query - a few minutes. Should be good enough?

Hi everyone.. I would like open up discussion about few changes to Peer. Please comment.
As of now, chaincode deployment works like this at a very high level.
1) chaincode source is packaged and sent to Peer for deployment.
2) Peer creates a docker image and starts the container and manages the lifecycle of the chaincode containers.
Some of the disadvantages I see..
1) Deploying chaincode takes longer.
2) Deploying means actually compiling source and creating a docker image on production servers. This is unnecessary and adds no value compared to starting a pre-built image.
3) Adding chaincode support for new programming language(s) requires changes to 'peer'.
I suggest "peer deploy" command should use the published docker image and starts a container.. This will avoid the above disadvantages.
pvishnum
2016-08-29 21:59
one clarification.. docker image doesn't need to be published to docker hub. It can be in a private docker registry
ghaskins
2016-08-29 22:52
This isn't tenable for a variety of use cases
ghaskins
2016-08-29 22:54
The relationship of the code and it's binary needs to be carefully controlled and driven through consensus. You lose that if the peers don't compile the code themselves
ghaskins
2016-08-29 22:55
That said, I think there are more efficient distribution models than those employed right now
pvishnum
2016-08-29 23:17
@ghaskins trying to understand... why is the deployment of code driven through consensus?

baohua
2016-08-30 05:56
@pvishnum Glad see your proposal. I also thought this idea before, but there are several disadvantages, a major one is about how to trust the existed image (to achieve that, lots need to change for the arch). However, I believe we should consider to make this process faster (e.g., caching, hot-loading), and less than 5 seconds should be good enough.

cbf
2016-08-30 13:47
this is the fabric channel, so the discussion tends to be more specific to the fabric. If you want to discuss the merits of each (fabric and sawtooth) suggest the #general or the #architecture channel wold be better suited
cbf
2016-08-30 13:48
both have their positive and negative attributes, like a parent and their children, hyperledger loves them both;-)
ashnur

Honestly, it seems to me that sawtooth is hugely dependent on the intel SGX architecture, and I haven't had the time to fully understand what is going around with that.

@ashnur, the current implementation of poet uses sgx, but your description is not accurate for sawtooth as a whole. consensus is pluggable. welcome discussion on #sawtooth

once that happens, those of you that use the vagrant devenv will need to vagrant destroy+up
ghaskins

those of you that roll your own, you’ll need to upgrade manually

Is it possible to deploy a chaincode from a private repo? If not, what’s the best deployment strategy to do it?
ghaskins
2016-08-30 23:52
@julio yes, you can either use the SDK, or you can run an NVP within your private domain
ghaskins
2016-08-30 23:52
then you can deploy chaincode from wherever you like, as long as it is accessible to the SDK/NVP node
julio
2016-08-30 23:53
@ghaskins Which sdk are you referring to?
ghaskins
2016-08-30 23:55
note that I believe the NVP/REST method is being deprecated at some point, though
ghaskins
2016-08-30 23:55
so, the SDK route has more long term viability
julio
2016-08-31 01:12
@ghaskins I’m not sure I understand. Will the node sdk download the git project or just forward the request to hyperledger?
ghaskins
2016-08-31 01:19
it will download it
ghaskins
2016-08-31 01:20
the SDK/NVP will do the URL->bytes translation, turning the request into a payload that is then broadcast on the consensus network

I found the problem of using v3.0.0-beta-3 that I can not create base image from scratch. This is not a problem of fabric, but "autogen.sh" in protobuf. The gmock has been merged to GoogleTest. As a result, the link is invalid. Here is a fix to autogen.sh.
ibmamnt
2016-08-31 03:54
```- curl $curlopts -O https://googlemock.googlecode.com/files/gmock-1.7.0.zip
- unzip -q gmock-1.7.0.zip
- rm gmock-1.7.0.zip
- mv gmock-1.7.0 gmock
+ curl $curlopts -L -O https://github.com/google/googlemock/archive/release-1.7.0.zip
+ unzip -q release-1.7.0.zip
+ rm release-1.7.0.zip

+ rm release-1.7.0.zip
+ mv googletest-release-1.7.0 gmock/gtest```
ibmamnt
2016-08-31 04:14
Actually, this modification might be easier.
file=<fabric>/images/base/scripts/common/setup.sh
```cd /tmp
curl -s -O https://raw.githubusercontent.com/google/protobuf/master/autogen.sh
git clone https://github.com/google/protobuf.git
cd protobuf
git checkout v3.0.0-beta-3
cp ../autogen.sh . ```
Hope this helps who has similar issue with me.

Hi, can someone tell me how to create new ECert/TCert for role based access for new user accounts in fabric
novusopt
2016-08-31 12:14
@balakrishna you mean you want to use custom users?
balakrishna
2016-08-31 12:15
yes. i want to register new users
balakrishna
2016-08-31 12:16
@novusopt yes, i want to register new user
garisingh
2016-08-31 12:23
@balakrishna - assuming you want to register users "dynamically" (i.e. not adding them to the yams file), then you'll want to use the NodeJS SDK in order to do this. https://github.com/hyperledger/fabric/blob/master/sdk/node/test/unit/registrar.js is a good unit test which shows the code needed to do this
jzhang

anybody seeing the error below? I have a local setup with docker-compose running inside Docker on Mac (not docker tools). To get this environment working, I had to manually pull hyperledger/fabric-baseimage:x86_64-0.0.10 and tag it with “latest”. Then I got the following error when deploying chaincode.

2016-08-31 13:16
@balakrishna the approach suggested by garisingh is correct
novusopt
2016-08-31 13:22
the easiest way is to adapt the config file: https://github.com/hyperledger/fabric/blob/master/membersrvc/membersrvc.yaml#L92
jzhang

about the error above, I had the setup running fine for a while until yesterday I cleaned up all images and restarted from scratch

When writing client applications for hyperledger, that is applications that will invoke and query the chaincode, what’s the best/idiomatic way to unwrap the data structures returned by chaincode?
ghaskins
2016-08-31 14:57
@jenkins I would encourage you to check out https://github.com/hyperledger/fabric-chaintool
ghaskins
2016-08-31 14:58
full disclosure, I am the author
ghaskins
2016-08-31 14:58
that said, alternatives exist such as using some other serialization format like json
jenkins
2016-08-31 15:00
@ghaskins Thanks, I’ll look into this. Mind if I PM you here if I run into anything I can’t work around?
ghaskins
2016-08-31 15:00
of course
jenkins
2016-08-31 15:01
@ghaskins Thanks again.
ghaskins
2016-08-31 15:01
fyi, there were a few changes to fabric mainline recently that may require some updates to chaintool, so theres a chance we will run into this
ghaskins
2016-08-31 15:01
but I can help you work through them, it will motivate me to fix the issues sooner rather than later

Hi guys. I am running 4 peers outside of vagrant using PBFT consensus. The peers keep exiting with the following error - error: accept tcp[::] 7051 accept: too many open files. I tried starting all the four peers at near same time and the first peer exited in around 20 mins and the rest of the peers exits with error in 50 mins time. I tried to increase the no. of open files limit as suggested in a similar issue https://github.com/hyperledger-archives/fabric/issues/651.
nikileshsa
2016-08-31 16:54
I tried increasing to 10000 and then to a larger value and I see the issue is still reproducible.

@ghaskins I tried looking for the function that does the URL to bytes translation but can’t find it. Could you please point it out to me?
ghaskins
2016-08-31 17:52
i can show you the NVP side, not sure about the SDK
ghaskins
2016-08-31 17:53
this is what is invoked on the NVP in the deploy of type GOLANG https://github.com/hyperledger/fabric/blob/master/core/chaincode/platforms/golang/package.go#L33
ghaskins
2016-08-31 17:53
each of the supported platforms has a similar function: https://github.com/hyperledger/fabric/tree/master/core/chaincode/platforms
ghaskins
2016-08-31 17:53
the resulting tarball is what is disseminated to peers
ghaskins
2016-08-31 17:54
the SDK has an equivalent function, as I worked with the SDK devs during its creation, but I am not familiar with the code to point to it
ghaskins
2016-08-31 17:54
all I know is that this logic was ported to TypeScript in the SDK, IIUC
ghaskins
2016-08-31 17:58
i did a quick search, i think the SDK is doing it here: https://github.com/hyperledger/fabric/blob/master/sdk/node/src/hfc.ts#L1616
ghaskins
2016-08-31 17:58
hope that helps

Hi, can someone explain, why the access to the transaction id within a chaincode has been removed...
bgorman
2016-09-01 08:30
@novusopt it may have been an unintentional side effect of adding the ChaincodeStubInterface
bgorman
2016-09-01 08:30
how did you access the transaction ID previously?
novusopt
2016-09-01 08:30

Hey gang. Is it possible to register a user that’s not defined in the membersrvc.yaml file? I’ve tried a new user but I get “sql: no rows in result set"
david.acton
2016-09-01 17:18
Before I start tearing apart my code, I’d thought I’d check if it was possible first
david.acton
2016-09-01 17:50
I’ve just answered my own question. .. It’s yes… the error “sql: no rows in result set” is not very helpful. :slightly_smiling_face:
jzhang
2016-09-01 18:10
@david.acton you can definitely register new users dynamically (not already in membersrvc.yaml), the error you are seeing is (almost certainly) due to corrupt user registry, I’d try blowing away the membersrvc and reboot (eg: —force-recreate if you use docker-compose)
julio
2016-09-01 21:21
@ghaskins Thanks for pointing that out.
david.acton
2016-09-01 22:47
@jzhang Thanks for your response. In this circumstance it was because I had done a refresh, but was using a registrar certificate from before I reset the membership srvc. BUT there’s no way to know this from the error message.
david.acton

All is good now
ashishkel

@jzhang : You mentioned that we can have users who are not present already in the membersrvc.yaml. How to do that? Is there a REST API ? or CLI ?
or is it just present only in Node SDK?
ashishkel
2016-09-02 05:11
Is there a master list of the Environment variables ( the CORE_<> variables) anywhere in the docs ? or any file?
bgorman
2016-09-02 05:12
@ashishkel the CORE_* environment variables map onto the variables in peer/core.yaml
bgorman
2016-09-02 05:13
e.g. CORE_PEER_ADDRESS matches the line
peer:
address: 0.0.0.0:7051
ashishkel

oh oh,, :slightly_smiling_face:

2016-09-02 06:59
@jzhang my feeling is that docker isn't interpolating the `$GOPATH` variable in the `hyperledger/fabric-baseimage` dockerfile. I can't overcome it yet though, so not sure.

@ashishkel the ability to dynamically add new users to memberservice’s user registry (an operation called “register user” in documentation) is available only via node.js SDK, chain.register() or chain.registerAndEnroll()
jzhang

@yannik yep I’ve also gathered as much, still not sure what exactly is the cause, because I double checked that $GOPATH is set both in the docker instance for the peer and also in the host environment (mac terminal in the case of Docker for Mac)

I am having the same issues as @bfuentes when I do vagrant up today : Tag latest not found in repository. I traced it to /fabric/images/src/Dockerfile.in but honestly I have no idea how to modify it so that it does not search for "latest" but instead, it looks for something else

no problem. we continue to learn more and more about the "limits" of how many containers you can actually get running on machine especially when using Docker's overlay networking. we hit some undocumented limits so we'll be adding more servers into the mix and should get more capacity out by tomorrow

Hi. What are recommended sys requirements for running fabric peer node? membership service?
I realize that it depends on the whole network setup, probably chaincode we are going to run etc.. but some starting point? or on what env IBM did their tests?

@garisingh can you share those "undocumented" limits with us?
garisingh
2016-09-05 22:29
@chainsaw - sure. It is really when you start to combine things like Linux, bridge interfaces, overlay networks, Docker and Swarm that things get interesting. Here's a few examples:
1) The Linux kernel has a hard-coded limit of 1024 virtual interfaces per bridge interface. This is of course sort-of known if you know Linux networking and you can work around it by creating multiple bridge interfaces. But - now let's say you want to use Docker's built-in overlay network driver AND the containers needs to connect to external networks. This results in a bridge network network being created automatically and overlay networks can only use this bridge network. End result: as far as we can tell, using the Docker overlay driver results in a limit of 1023 containers per host
2) Docker Swarm calls RefreshNetwork as part of every CreateContainer call. The larger the number of containers on the overlay network, the more expensive this call becomes and the longer it takes to start each container. (FYI - looks like there is a fix for this in the current master branch for Swarm and we'll take a look at that)
3) There are a number of other setting which we have learned about via trial and error as well:
- parameters like `net.ipv4.neigh.default.gc_thresh1`, `net.ipv4.neigh.default.gc_thresh2`,`net.ipv4.neigh.default.gc_thresh3` need to be set much higher than the defaults in order to avoid arp table overruns
- parameters like `vm.dirty_ratio` and `vm.dirty_background_ratio` need to be properly set to lower values when you have a lot of containers which write to disk else Ubuntu will hang due to task timeouts
The reality is that there really is no documentation / documented best practices of trying to run things like Swarm at massive scale when you need things like overlay networks, have stageful containers, etc.

And just in case you don't know what we do / try to do, one part of my job is to own the Bluemix Blockchain Service where we run 4 peer + CA PBFT networks for our customers. We run this in a shared environment using Docker Swarm for the peers and CAs and another Docker Swarm to run the chaincode. So we try to run as many containers per host as we can (well that was the hope). Right now we have about 6500 containers running peers and CAs across 8 host systems
garisingh
2016-09-05 22:38
on the prior version of our service, we didn't use overlay networks (but that caused us other issues) and we had about 15000 containers running peer and CAs across 32 VMs

2016-09-05 23:13
Cool dude! I get it all and then some :slightly_smiling_face: Thx for sharing this. For the last several months I've been using Bluemix IBM Blockchain (your baby) for my technical education sessions teaching engineers how to develop chaincode, build Hyperledger Fabric, and soon how to architect for real-world blockchain/chaincode applications. This helps confirm some of my suspicions. Personally, I advise clients against swarm unless they have use cases that suit it, otherwise, I have found other proprietary ways to get around the scaling, discovery, and inter/intra-container communication issues. Did you read the PR from Verizon stating they successfully cranked an IoT infrastructure running 40,000 docker containers? It was to be their platform for competing in the IoT space.

@cbf Hi, I'm using v0.6 and it seems to be pretty stable. However, we can see that there is a lot of "work in progress" in there.
IMHO, the v0.6 release should at least include these patches to be considered "polished" for chaincode development, without too much upgrade issues (I ran into issues translating v0.5 to v0.6 chaincode because those were missing)
https://gerrit.hyperledger.org/r/#/c/729/ Use stub to get arguments in chaincodes

start with the hyperledger/fabric/docs/protocol-spec.md document ... note that no one peer controls the transaction ordering, this is done by all the peers through the pbft consensus protocol

@tuand - I have read protocol specification, especially http://hyperledger-fabric.readthedocs.io/en/latest/protocol-spec/#3211-block I don't see here any settings for timeouts or block size. So what are the rules for peer to put few transactions in the block, i.e. when to generate a block? This is first.
The second one - I don't think that consensus protocol take part in building block itself, or am I mistaken? My understanding was that with current impl, there is a leading peer, which build the block and propagating it to the ledger (other peers) - which is still unclear. Actually transaction ordering really matters while executing transactions.
tuand
2016-09-07 18:31
transactions are batched before being processed. This is configured via the hyperledger/fabric/consensus/pbft/config.yaml file. 2 parameters : batchsize ( how many transactions in a batch ) and timeout_batch ( send a batch through even if batchsize is not reached ). pbft has the concept of a primary which assigns a sequence number and starts consensus by sending what's called a pre-prepare msg to the other peers.
tuand
2016-09-07 18:34
there's no leader election. The peers are named vp0,vp1,vp2 ... vpN . You start with vp0 as the primary. At any time, the other peers can decide that a new primary is needed ( a view-change in pbft speak ) and the primary switches to the next peer in sequence
tuand
2016-09-07 18:34
pbft is better described in the Castro and Liskov paper referenced in the protocol-spec doc
tuand
2016-09-07 18:35
also, this is if you're using pbft. If you're using noops, each transaction is processed individually
tuand
2016-09-07 18:37
and the consensus folks tend to use #fabric-consensus-dev so come on over :slightly_smiling_face:
oiakovlev
2016-09-07 18:38
that's really makes more sense, thanks
oiakovlev
2016-09-07 18:40
and just to double check: transactions are processed by peer one by one in the block, so let's say there can be no race condition right now?
tuand
2016-09-07 18:40
right
oiakovlev
2016-09-07 18:42
so as long as we have block, we have deterministic order - that's why we are on safe side working with the hashed values...
tuand
2016-09-07 18:42
note though that 2 or more clients can send transactions simultaneously ... in that case, order is arbitrary
oiakovlev
2016-09-07 18:43
yes, I got it, but see my comment above: as long as peer built the block and propagated it to other peers it is deterministic
oiakovlev
2016-09-07 18:44
so it is a bit incorrect to say but it is like all invocations are synced using some common mutex object?
tuand
2016-09-07 18:45
no propagation ... all peers consent on the ordering then each peer executes all transactions in the sequence agreed upon
oiakovlev
2016-09-07 18:46
ok it is about terminology - `consent on the ordering` as you mentioned above there is still some primary peer... anyway details here might not matter it is necessary to understand the idea... Thanks...
tuand
2016-09-07 18:50
ok ... I do recommend the Castro and Liskov paper as what we have in fabric is a pretty close implementation of that paper. Also see Christian Cachin's paper "Yet another visit to Paxos"
oiakovlev
2016-09-07 18:51
Thanks again. I'll have a look at it - I have read protocol spec but guess that still have some gaps in understanding.
Also one more silly question: Is my understanding correct here that the max time to execute the block will be: `batchsize*timeout` (transaction timeout) or also some PBFT specific timeouts can take a role here? I mean if I write 'bad' chaincode which executes really long it will impact the throughput or not?
tuand
2016-09-07 18:54
no, execution is on another thread. take a look at hyperledger/fabric/pbft/config.yaml for the timeouts you can tweak
tuand
2016-09-07 18:56
fabric does assume that a chaincode is deterministic and does not validate that the peers have the same result. More than a few folks have been bitten by this. Take a look in github-archives for issue #1981
oiakovlev
2016-09-07 18:59
Thanks, I'll have a look, it was really helpful to get these answers. Could I use your kindness again some time after reviewing all this and ping you here, if have any further question?

Have asked it yesterday will try once more :slightly_smiling_face: : Is there any option to get historical 'versioned' values from KVS? So for example is there any easy way to retrieve all values, which some key had? Or do I get versioning terminology a bit wrong and it doesn't support this?
dave.enyeart
2016-09-08 20:35
It is not possible to get the past values from KVS, this is being looked at for a next major release.
oiakovlev
2016-09-08 20:44
thanks a lot! means v0.6, right?
oiakovlev
2016-09-08 20:44
or 0.6 is a minor one?
dave.enyeart
2016-09-08 20:47
the major design changes around endorsement model and new ledger are targeted for v1, but may get previewed in one of the minor releases leading up to v1

venkat
2016-09-08 21:00
just wondering: Does the consensus happen at block level or at txn level? If it is at transaction level, what happens if some txns in a blcock fail to get consensus? (posted in general, but thought more relevant here)
venkat
2016-09-08 22:13
one more q: can we use an SQL store for the chain state and use SQL statements to quey data? The statehash could be a problem, may be?
tuand
2016-09-09 00:01
@venkat it depends on the pbft batch size . If batchsize=1 then consensus is done on each incoming transaction, if batchsize=x where x>1 then consensus is done on the batch of x transactions
tuand
2016-09-09 00:02
I'll ask @dave.enyeart or @manish-sethi to chime in on the data store question
oiakovlev
2016-09-09 00:04
but just to double check: when consensus is done on the batch, if there is transaction(s) which is(are) not accepted by consensus, what happens? They are simply excluded from batch or the whole batch is rejected?
tuand
2016-09-09 00:33
The whole batch is treated as one
manish-sethi
2016-09-09 04:30
@venkat in 0.6 branch which is based on current architecture, it is easy to use an SQL store for using a richer data model from chaincode perspective - So a chaincode could maintain it’s state in relational form.
However, you pointed out the exact point of difficulty which is computing the statehash. Also, other related difficulty would be to maintain the stateDeltas which are used during state transfer if a peer is a few blocks behind.

2016-09-09 10:19
@oiakovlev check http://goo.gl/CG9Qwi -- it has an attachment which has a basic timeline (dont know how the guys are keeping up with the schedule so far)
also, regarding the consensus reject: batches are treated as one and rejected as one, but single transactions can still fail on the chaincode (from reasons like system errors, timeouts, to ledger state related execution rejection - "wont do that transaction, you dont have enough funds on your account")
deeflorian
2016-09-09 10:21
ledger state should match on peers, so rejects like the latter should happen on all peers, resulting in a consistently not changed state on every peer (not sure on the fault-tolerancy though, what happens if a single peer has a bit-error of some sorts? used to be an issue, but i'll need to look into the current code to check)

I've cloned the "learn chain code" repo (https://github.com/IBM-Blockchain/learn-chaincode.git)and trying to build the very first program with Go
when I run " go build ./ " it spits out following error
\chaincode_start.go:34: cannot use new(SimpleChaincode) (type *SimpleChaincode) as type shim.Chaincode in argument to shim.Start:
have Init(*shim.ChaincodeStub, string, []string) ([]byte, error)
want Init(shim.ChaincodeStubInterface, string, []string) ([]byte, error)
Any ideas ?

Here is some good info on the maximum number of Dockers you can run in a Host, in addition to excellent undocumented information provided by @garisingh on Sept 5th.
chainsaw
2016-09-10 16:35
The figures below are from the boot2docker 1.11.1 vm image which is based on Tiny Core Linux 7. The kernel is 4.4.8
Docker
Docker creates or uses a number of resources to run a container, on top of what you run inside the container.
Attaches a virtual ethernet adaptor to the docker0 bridge (1023 max per bridge)
Mounts an AUFS and shm file system (1048576 mounts max per fs type)
Create's an AUFS layer on top of the image (127 layers max)
Forks 1 extra docker-containerd-shim management process (~3MB per container on avg and sysctl kernel.pid_max)
Docker API/daemon internal data to manage container. (~400k per container)
Creates kernel cgroups and name spaces
Opens file descriptors (~15 + 1 per running container at startup. ulimit -n and sysctl fs.file-max )
Docker options
Port mapping -p will run a extra process per port number on the host (~4.5MB per port on avg and sysctl kernel.pid_max)
--net=none and --net=host would remove the networking overheads.
Container services
The overall limits will normally be decided by what you run inside the containers rather than dockers overhead (unless you are doing something esoteric, like testing how many containers you can run :slightly_smiling_face:
If you are running apps in a virtual machine (node,ruby,python,java) memory usage is likely to become your main issue.
IO across a 1000 processes would cause a lot of contention.
1000 processes trying to run at the same time would cause a lot of context switching (see vm apps above for garbage collection)
If you create network connections from a 1000 containers the hosts network layer will get a workout.
It's not much different to tuning a linux host to run a 1000 processes, just some additional Docker overheads to include.
Example
1023 busybox images running nc -l -p 80 -e echo host uses up about 1GB of kernel memory and 3.5GB of system memory.
1023 nc -l -p 80 -e echo host processes uses about 75MB of kernel memory and 125MB of system memory
Starting 1023 containers serially took ~8 minutes.
Killing 1023 containers serially took ~6 minutes

Hi All,
joseph
2016-09-13 04:25
In the specification, it mentions that the world state of a peer is computed by a crypto hash function.
joseph
2016-09-13 04:27
My question is how a chaincode can read data from data from the world state?
bgorman
2016-09-13 04:48
@joseph each peer maintains a local copy the state, from which a hash is calculated to verify the state is equal on all peers
bgorman
2016-09-13 04:49
chaincode can request a copy of any part of the state from the hosting peer
joseph
2016-09-13 04:52
@bgorman: Thank you for you reply. But I wonder how can a chaincode read an one-way encrypted data from the world state?
bgorman
2016-09-13 04:52
the hashes are not the world state
bgorman
2016-09-13 04:52
each peer has a complete copy of the world state
bgorman
2016-09-13 04:52
the hash is merely used to verify that each peer has the same world state
bgorman
2016-09-13 04:52
the chaincode can access the peer's full copy of the world state
bgorman
2016-09-13 04:53
e.g. if each peer's state hashes to the same value, everything is good.... if one peer has a different hash, it needs to re-do its calculations (I'm guessing here)
bgorman
2016-09-13 04:54
if you can reverse a one-way cryptographic hash, please DM me :smile:
joseph
2016-09-13 04:55
When we PutState(), where are data stored?
bgorman
2016-09-13 04:55
on the peer, in a RocksDB instance
joseph
2016-09-13 04:56
Can we see the data in that instance if we access to the peer?
bgorman
2016-09-13 04:57
chaincode definitely can
bgorman
2016-09-13 04:57
I guess RocksDB has a general API that you could use too
bgorman
2016-09-13 04:58
I'm not sure how advisable is... defintely don't change the data :slightly_smiling_face:
joseph
2016-09-13 04:58
I wonder so can hack into a peer and change data directly on RocksDB instance.
joseph
2016-09-13 05:00
Is that possible?
bgorman
2016-09-13 05:01
um... I guess it could be
bgorman
2016-09-13 05:02
it would mean that peer wouldn't reach consensus and the others would carry on
joseph
2016-09-13 05:17
I see. And there is no relation between world state and RocksDB instance.Right?
bgorman
2016-09-13 05:37
the RocksDB holds the world state, so there is a relationship there :slightly_smiling_face:
joseph
2016-09-13 05:43
We can say that
joseph
2016-09-13 05:46
When we PutState("abc", "xyz"), the ledger will store that pair ("abc", "yxz") into RocksDB instance and the world state. And the world state is stored in RocksDn instance also. Right?
bgorman
2016-09-13 05:49
sounds good to me, yes
bgorman
2016-09-13 05:49
PutState() actually modifies the world state
bgorman
2016-09-13 05:49
you could call it PutWorldState() if you wanted :slightly_smiling_face:
joseph
2016-09-13 05:53
Do you know what type in source code of the fabric refers to the world state?
bgorman
2016-09-13 05:58
from the chaincode it's PutState() and GetState()
joseph
2016-09-13 06:03
I means what Golang struct in the source code that represents the world state?
joseph
2016-09-13 06:05
I see it.
joseph
2016-09-13 06:05
type State struct {
stateImpl statemgmt.HashableState
stateDelta *statemgmt.StateDelta
currentTxStateDelta *statemgmt.StateDelta
currentTxUUID string
txStateDeltaHash map[string][]byte
updateStateImpl bool
historyStateDeltaSize uint64
}

hm, seems my submission failed to build due to bad imports? It's supposed to be built as part of chaincode, not with the fabric
pschnap
2016-09-13 21:04
(the directory I placed it in is probably not the correct one, but it seemed logical)
garisingh
2016-09-13 21:06
what's your change?
pschnap
2016-09-13 21:12
it's a module that will automatically unmarshal arguments to chaincode "function" invocations; you create a map of "functionName"->function pairs that can respond to an invocation or a query and my module uses reflection to parse the args[] array into the argument types specified by the function being called
pschnap
2016-09-13 21:12
because manual args checking is annoying boilerplate :slightly_smiling_face:
ghaskins
2016-09-13 21:22
obviously I am partial to protobuf/chaintool…can you highlight for us where you see this fitting in? Is it an alternative to chaintool “CCI”, something that enhances it, etc
pschnap
2016-09-13 21:26
I haven't seen what the chaintool can do (I've only been on the periphery of this project). When I first made inquiries you in particular seemed interested in the idea (though we didn't have a chance to discuss it further)
ghaskins
2016-09-13 21:27
And I still am, just trying to understand
pschnap
2016-09-13 21:30
It's something that would allow anyone writing chaincode manually to avoid having to do manual args checking and parsing from strings; instead they would provide well-typed functions and the module would do the parsing for them
pschnap
2016-09-13 21:31
mostly just a convenience
ghaskins
2016-09-13 21:32
with the caveat that I still need to dig in and review, it sounds like it might have relevance to the golang-shim
ghaskins
2016-09-13 21:33
we currently support three chaincode types: “GOLANG” (the original, unmanaged chaincode), “CAR” which is chaintool managed, currently only supports golang based chaincode, and JAVA
ghaskins
2016-09-13 21:34
it sounds like we could add your work under the GOLANG umbrella and it could assist chaincode developers using that form factor
pschnap
2016-09-13 21:35
ah, sorry, i should have specified that it was meant for the golang chaincode from the beginning
ghaskins

@suri you should just be able to run the binary, or if you want it in the background, you can run `nohup membersrvc&`

guys I just found the docs for the shim package: https://gowalker.org/github.com/hyperledger/fabric/core/chaincode/shim
mart0nix
2016-09-14 09:41
and I see there's some kind of a Table functionality
mart0nix
2016-09-14 09:41
are there any good tutorials/examples on the shim API beyond the put/get State
hgabor
2016-09-14 09:46
it seems there aren't any :S
hgabor
2016-09-14 09:46
btw I just checked the tests, they usually contain good examples
hgabor
2016-09-14 09:46
@muralisr ?
muralisr
2016-09-14 11:29
@mart0nix there is one under fabric/bddtests/chaincode/go/table
mart0nix
2016-09-14 11:29
@muralisr great - I will check it out
mart0nix
2016-09-14 11:30
is this some kind of a SQL table ? :))
muralisr
2016-09-14 11:30
no :slightly_smiling_face:
mart0nix
2016-09-14 11:30
what kind of data storage is it appropriate for ? How do you query it ?
oiakovlev
2016-09-14 11:30
I guess it is some linked key-values at the end? is my understanding correct?
oiakovlev
2016-09-14 11:31
so it might be really expensive queries or not really?
mart0nix
2016-09-14 11:32
muralisr
2016-09-14 11:32
@oiakovlev right, "columns and rows” are implemented based on the same key-value storage used in get/put
muralisr
2016-09-14 11:33
@mart0nix asset management with a chaincode usually maps to a table structure
muralisr
2016-09-14 11:34
along with the examples its best to look at the APIs for the table to understand its usage
mart0nix
2016-09-14 11:34
got it
mart0nix
2016-09-14 11:34
one more question - related to the scalability of extracting transaction payload data as a mechanism to query a data model
mart0nix
2016-09-14 11:35
this is the approach in the car lease demo
mart0nix
2016-09-14 11:35
how scalable is this ?
muralisr
2016-09-14 11:36
querying the blocks for transactions and “building up” history ?
mart0nix
2016-09-14 11:36
yeah
muralisr
2016-09-14 11:36
(I haven’t looked at car lease demo recently)
muralisr
2016-09-14 11:37
its hard to say without looking into the app … I assume they do this to avoid grwoing the global state
muralisr
2016-09-14 11:38
oh I see
garisingh
2016-09-14 11:40
@mart0nix - the car lease demo basically built a block viewer. Is that what you are asking about? And as I recall, it will only bring back the latest X blocks (although I think you can scroll back). We also implemented this same concept in the BMX dashboard for blockchain and it's also part of the explorer project recently contributed to hyperledger
mart0nix
2016-09-14 11:41
@garisingh that's the feedback
mart0nix
2016-09-14 11:41
I'm basically developing an app that involves an asset that changes hands many times until it reaches its final destination
mart0nix
2016-09-14 11:42
while it's clear to me how to maintain current status in the world state
mart0nix
2016-09-14 11:42
I'm exploring scalable ways of recording the history of that asset
mart0nix
2016-09-14 11:42
so that I can query an asset with a serial number 1234566 and see all the history (change of custody/ownership)
garisingh
2016-09-14 11:43
well there's the short term and long term answer. The long term answer is that the fabric v1.0.0 will have the ability to query historical state
garisingh
2016-09-14 11:45
this was a gap identified in the current architecture. Also - the blocks don't technically contain the actual state at any point in time (they have the transaction and state deltas - but you'd still need to know a starting or ending state plus which transactions modified which keys)
garisingh
2016-09-14 11:47
so people have tried various ways to achieve what you want:
1) You have a single key per asset and a value structure which has an array of historical things you want to track
2) You can attempt to use range queries where your prefix is your asset number
3) You can try to use the table APIs (which are higher level abstraction on doing 2) )
muralisr
2016-09-14 11:48
right, more “state” as opposed to just “transaction” information you need to manipulate, more you have to do it with chaincode logic
muralisr
2016-09-14 11:49
one more way - create a new chaincode for each asset (which is inefficient for most use cases)
garisingh
2016-09-14 11:50
I've also consider maintaining this outside the blockchain - where you could always point back to the block which contained the transaction as well
mart0nix
2016-09-14 11:51
@garisingh well the transaction itself could be used as a data model unit
mart0nix
2016-09-14 11:51
if you can extend the protocol and include indexed values
mart0nix
2016-09-14 11:51
seller: ...., buyer, .... serial_number ...
mart0nix
2016-09-14 11:53
use some kind of a scalable data structure to index the fields that could be used as filter criterias
mart0nix
2016-09-14 11:54
bloom filter or something like this
mart0nix
2016-09-14 11:54
does that make sense ?
garisingh
2016-09-14 11:54
so this is pretty much what we are doing with the new ledger in v1.0.0
mart0nix
2016-09-14 11:55
oh nice
mart0nix
2016-09-14 11:55
when is v1.0.0 due ?
mart0nix
2016-09-14 11:55
: )
garisingh
2016-09-14 11:56
in progress now with incremental deliveries every month. hopefully in a few weeks we'll have the basic happy path working across all the new components
mart0nix
2016-09-14 11:58
so v1.0 will come out before the end of this year or ...?
mart0nix
2016-09-14 11:59
I'm trying to figure out if I should start working on a work-around. If it's going to be only a few weeks for v.1.0 I may as well just wait since that sounds like the right way to do these kinds of things
garisingh
2016-09-14 12:06
well we'll have working code by end the year - official release is targeted for March 2017
muralisr
2016-09-14 12:08
@mart0nix the other option would be to build the chaincode with the limitations … that way you can check if the features solve those as and when they come in ?
muralisr
2016-09-14 12:09
pros and cons of course… just a thought
mart0nix
2016-09-14 12:11
well thanks for the info. I think I will read some more examples to figure out how easy it would be do implement my use case
mart0nix
2016-09-14 12:11
my use case involves unique serial identifier
mart0nix
2016-09-14 12:12
which kinda makes it easy
mart0nix
2016-09-14 12:12
but the issue is that there's meta information that should also be query-able (owner, timestamp, etc...) in addition to the the unique identifier
mart0nix
2016-09-14 14:09
hmm
mart0nix
2016-09-14 14:09
what about logging abilities ?
mart0nix
2016-09-14 14:10
I see there's a chaincode logger
mart0nix
2016-09-14 14:10
where do the log files get stored ?
lbonniot
2016-09-14 14:27
Hi, is there any announced release date for the v0.6-dev-preview ? Thx
ghaskins
2016-09-14 16:18
who are the best contacts for the Z and P platforms?
ghaskins
2016-09-14 16:18
in terms of working to get resources for the jenkins pipeline
ghaskins
2016-09-14 16:19
@vpaprots you are my best bet on the Z side
ghaskins
2016-09-14 16:19
any pointers/introductions helpful
garisingh
2016-09-14 16:19
I think Z but be a little behind as they have a lot of other things going on. Let me find the right person on the P side
ghaskins
2016-09-14 16:19
@garisingh thank you
ghaskins
2016-09-14 16:20
i feel like part of the reason they are behind is because in the past I have been a gate for baseimage
ghaskins
2016-09-14 16:20
part of what I am working on now is automating this process, but I want to line up the z/ppc stuff too so it doesnt get even more further behind
garisingh
2016-09-14 16:21
agreed - because actually we want to get Power images being published to dockerhub for the v0.6 release in line with the x86 images. Z as well if possible but their resources are tied up on a few other things
ghaskins
2016-09-14 16:22
cool….well, i think as long as we can get a jenkins worker for whatever $arch you want, it should be straight forward
ghaskins
2016-09-14 16:22
(assuming it can reasonably execute a docker build, etc
ghaskins
2016-09-14 16:23
LF has a nice cloud/openstack based setup for x86…it just creates an ephemeral VM whenever I start a new build-job
ghaskins
2016-09-14 16:23
but it doesnt have to be that sophisticated
ghaskins
2016-09-14 16:23
as long as jenkins can use it
garisingh
2016-09-14 16:26
cool. just pinged my contact on Power for him to have their automation guy(s) reach out to you
ghaskins
2016-09-14 16:27
ty
vpaprots
2016-09-14 16:58
@ghaskins I have been busy with all the z crypto stuff.. but yeah, seems we fell off the CI bandwagon.. I actually been making lots of loud noises about that to anyone who will listen. @harrijk John is a great resource for building things on z (https://github.com/harrijk/docs)
vpaprots
2016-09-14 16:58
it would be nice to get that into fabric at some point..
ghaskins
2016-09-14 17:00
ty @vpaprots
ghaskins
2016-09-14 17:00
what we need in this case is someone who will work with LF on providing jenkins worker resources for the $arch in question
ghaskins
2016-09-14 17:00
i know Z already has something in place, though my understanding is it is currently offline
ghaskins
2016-09-14 17:01
it doesnt look like P has any representation at all right now
vpaprots
2016-09-14 17:03
Ramesh has always been my point man on the builds, he monitored them and poked me every time something breaks.. I've been arguing that we need somebody full time for Z to keep up with build breaks. We are spread bit thin atm with all the things we like to get in..
ry
2016-09-14 17:04
Z VMs were recycled AFAIK
ghaskins
2016-09-14 17:09
ultimately I wont be gated by anything != x86, but I wanted to queue up the alt-arch conversation so its not a surprise to anyone

@ghaskins , @srirama_sharma and I are working on uploading docker images for v0.6 release. I have seen your comment regarding resources contact for Power. I am working with Ramesh to have the builds in the community CI.
ghaskins
2016-09-14 19:48
ok cool…as long as there are jenkins workers for power that are capable of running docker-build, i think ill have what I need
ghaskins
2016-09-14 19:49
can you explain in more detail what you mean by “working on uploading” ?
bsmita
2016-09-14 19:49
The Power node is not enabled yet, but prep work was done on it, we are waiting on the v 0.6 branch cut, so
ghaskins
2016-09-14 19:49
(by that, i mean, what process are you using
ghaskins
2016-09-14 19:49
because IIUC, all uploads will be done by jenkins eventually
bsmita
2016-09-14 19:50
Ramesh put a patch in place to support Power platform, so when the build pass unit-test, behave test, the Jenkins master will upload images to dockerhub
ghaskins
2016-09-14 19:50
ok, good
ghaskins
2016-09-14 19:50
we need to coordinate on image/tag names though, so keep me in the loop on this
bsmita
2016-09-14 19:52
Sure, we are waiting for v0.6 branch so that Ramesh can point the Jenkins build to a private repo and try a build. We are planning a private repo now due to FAB#358
bsmita
2016-09-14 19:52
Srirama is working on a patch for this issue.
ghaskins
2016-09-14 19:53
let me know as soon as there is a ppc worker available that I can test with
bsmita
2016-09-14 19:54
The power node is online now, if that's what you are looking for

@ghaskins sure.
ghaskins
2016-09-14 19:55
@ry I see “hyp-power-1” idling in production jenkins, but its not in sandbox….possible to expose it there too?
ry
2016-09-14 19:56
@ghaskins: I'm at lunch will get to it soon
ghaskins
2016-09-14 19:56
@ry no rush, thx
garisingh
2016-09-14 20:43
@ghaskins let me know when we try to figure out the actual image names and tags
ghaskins
2016-09-14 20:45
@garisingh ok…i think it will really boil down to one of two options
ghaskins
2016-09-14 20:45
$(name)-$(arch):$(version), or $(name):$(arch)-$(version)
ghaskins
2016-09-14 20:46
currently, the stuff I have worked on has used the latter but some of the stuff @ramesh has been doing uses the former
ghaskins
2016-09-14 20:46
I used the $(arch)-$(version) stuff in the past because :latest wasnt a relevant consideration at the time
ghaskins
2016-09-14 20:46
however, @ramesh does bring up a good point about it now
ghaskins
2016-09-14 20:47
so its something to consider
ghaskins
2016-09-14 20:47
im a little torn: with the new versioning stuff I have recently introduced and continue to refine, the :latest tags become an actual possibility
ghaskins
2016-09-14 20:47
but, it bothers me a little bit that it forces _everything_ to make $arch explcit
ghaskins
2016-09-14 20:48
e.g. “docker run hyperledger/fabric-x86_64-peer” seems awkward
ghaskins
2016-09-14 20:48
but that said, without that, we cant have latest at all
garisingh
2016-09-14 20:48
$(name)-$(arch):$(version) is the option I vote for FWIW
ghaskins
2016-09-14 20:48
so I see his poit
ghaskins
2016-09-14 20:49
point
ghaskins
2016-09-14 20:49
cool, i think its the way I am leaning too
garisingh
2016-09-14 20:50
I'll be completely transparent here - I want to be able to put out a set of docker compose files and need to be able to explicitly choose the "version" but also need multi arch support. I think that if we plan to use Docker as a delivery vehicle for releases, that is the best way to go
ghaskins
2016-09-14 20:50
one possibility (and no offense to my P/Z brethren), a middle ground could be we special case x86
garisingh
2016-09-14 20:50
yes
garisingh
2016-09-14 20:50
I think that's fine
ghaskins
2016-09-14 20:51
e.g. x86 is undecorated
garisingh
2016-09-14 20:51
as long as we use the version as the tag, I'm good
ghaskins
2016-09-14 20:51
yeah, thats a given
garisingh
2016-09-14 20:51
perhaps some day Dockerhub will have arch support
ghaskins
2016-09-14 20:52
I thought IBM had some contributions going in in that regard?
garisingh
2016-09-14 20:52
I think so as well since we have 2 of the big architectures that need to be supported

quick question ... latest code in archives (compatibility with 0.5 necessary) ... deploying via modified yeasy/docker-compose ... and I get this error when spinning up the network ... deploy was previously successful, but this error was masked because I had a residual env var for DEBUG level logging lying around (bad idea with pbft) ...
vp1_1 | 21:27:23.659 [dockercontroller] Start -> ERRO 027 start-could not start container API error (400): {"message":"starting container with HostConfig was deprecated since v1.10 and removed in v1.12"}

Thoughts on what a quick fix might be? It seems I have the latest docker ... do I need to downgrade?
kletkeman
2016-09-14 21:59
looks like the API error is real and a product of docker-java issues ... downgrading is the recommended solution but failed for me ...
kletkeman
2016-09-14 21:59
so ... anyone else run into docker 1.12 failures? or has the launch method perhaps changed in Gerrit?
kletkeman
2016-09-14 22:01
here is the issue that is tracking this problem: https://github.com/docker-java/docker-java/issues/617

2016-09-14 22:12
kletkeman we’re using this for CI: "Ubuntu 14.04.4 - fabric - DOCKER 1.8.5 PROTOC 3.0 JQ 1.5 VAGRANT 1.8.5 - 20160909.1534"
ry
2016-09-14 22:12
we took multiple bites of the Docker 1.1[012] apple and it didn’t work for us
kletkeman
2016-09-14 22:21
@ry And so I am finding as well. I tried downgrading to 1.8.x and was stopped by permissions on a wget. I suppose I will dig around and find that version and just copy it over top of the 1.12 as was suggested in some other thread somewhere. Sigh ... who'd a thunk that Java chaincode support was going to throw such a nasty wrench into this project ... thanks for the confirmation.

2016-09-14 22:23
@kletkeman It has been a frustrating journey, for sure.
kletkeman
2016-09-15 00:08
@ry It looks like go-dockerclient needs to be updated for 0.6 in order to work with API 124 ... I don't know if that will happen, so I guess I'll take the pain of rebuilding my dev environment with the older versions ...

2016-09-15 00:51
So if the go-docker client just needs an update, that is preferable
ghaskins
2016-09-15 00:51
That said, pinning it in general seems like a good idea
ghaskins
2016-09-15 00:52
I'll roll that into the plan
kletkeman
2016-09-15 00:54
@ghaskins there have been changes to start container in the newer version of the go-dockerclient here: https://github.com/hyperledger/fabric/blob/24c7483a2154df5a2d915b1a3b656e914cde7501/vendor/github.com/fsouza/go-dockerclient/container.go#L674-L703 ... I presume that using the latest docker version isn't causing anyone issues in the newer repository?
ghaskins
2016-09-15 00:55
Oh i see
ghaskins
2016-09-15 00:56
So this is only a problem since the old devenv and old fabric use docker:latest
ghaskins
2016-09-15 00:56
But if you are current, everything works?
ghaskins
2016-09-15 00:57
Guess nothing can be done for old code in that case, but pinning it should mitigate this from happening again
kletkeman
2016-09-15 01:00
@ghaskins Well, I've been fighting to get a 4 peer network functioning for a couple of days now ... the doc split makes that a little tougher than necessary and the crush of debug statements doesn't help. At some point, I got everything working just as I upgraded the docker version ... that was a bad call on my part. There was some elusive reason why I did it, but of course backing it out has cost me hours. I've been forced to rebuild vagrant from scratch and that is now failing to recreate the peers ... it's always something it seems. So the short answer is "I think so" ... as in everything should work once I get my environment sane again. By the way, with 4 peers and pbft, the four peer containers take a really long time to appear. But they do eventually ...
kletkeman
2016-09-15 01:01
Oh ... I should be more clear ... part of that time was trying to debug on bluemix, and I had to give that up when 2 peers crashed out of the blue. But looking at logs on there is pretty annoying, which is why I decided to go docker-compose etc ...
kletkeman
2016-09-15 03:14
hmmm ... blew away the vagrant vm, built it all up from scratch, replaced the go-dockerclient and rebuilt the peer, and no change ... I guess the downgrade of docker is mandatory ...

@suri and you are running your peer with `--peer-chaincodedev`?
bgorman

},
bgorman

ghaskins
2016-09-15 19:33
@zaki are you running compose from the devenv?
ghaskins
2016-09-15 19:34
if you are running from the devenv, the docker configuration should already be set up properly for you
ghaskins
2016-09-15 19:34
if you are not, I suspect you need to set your DOCKER_OPTs appropriately
cbf

@zaki native docker or docker toolbox? if native then I believe that the missing ingredient is the need to mount /var/run/sock.... let me dig up the example
ghaskins

This is probably more of a Docker issue than an HL issue, but does anyone know how to resolve this?
```

docker: An error occurred trying to connect: Post http://%2Fvar%2Frun%2Fdocker.sock/v1.24/containers/create: read unix @->/var/run/docker.sock: read: connection reset by peer.

```
ccooper21
2016-09-16 05:26
I had successfully built the peer before, but the IP address of my VM has changed since then. I'm guessing this is contributing the error, but I'm not sure where it may be stored.

can we modify the .yaml file which is inside the chaincode after deploying it to the chain
cbf
2016-09-16 11:56
@ranjan008 that config is for the membersrvc component, not the chaincode. Please read the README here: https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management02
cbf
2016-09-16 11:57
Basically, the asset.yaml is used by the asset_management02_test.go test (use go test to run the test) to configure the membersrvc with the necessary identities
ranjan008
2016-09-16 11:58
@cbf yes ofcource but if i am adding some user after deploying the chaincode in the chain and i want to give access to the user for that chaincode can that be done
cbf
2016-09-16 11:58
not yet, there is, I believe, a patch being reviewed to add dynamic addition of users via the SDK

ibm-blockchain-js is not the same thing as the new SDK HFC...correct ?
cbf
2016-09-16 12:33
no, the ibm-blockchain-js was written before the node SDK (hfc). I don't believe that it is current with master. It is pegged to what was running in Bluemix (v0.5).
cbf
2016-09-16 12:34
@mart0nix we just merged some improvements to the nodeSDK documentation. There's a fully working example (as opposed to a fragment)

garisingh
2016-09-16 14:10
@mart0nix - my guess is that you did a cut and paste directly from the html page you posted above. Basically when you do that it did not preserve formatting. Easiest thing to do is to hit the "Raw" button and then copy the contents from there (you'll see that you now have proper indentation / formatting)
mart0nix
2016-09-16 14:12
@garisingh well the reason I copied and pasted was because the link was broken: https://raw.githubusercontent.com/hyperledger/fabric/master/examples/sdk/node/example02/docker-compose.yml
mart0nix
2016-09-16 14:12
I get a 404 for that
garisingh
2016-09-16 14:15
yeah - figured that. so just view the "Raw" content of that page and copy the contents from there and you should be good (at least format wise)

@ccooper21 you probably need to set CORE_VM_ENDPOINT to the right docker daemon endpoint. It defaults to unix:///var/run/docker.sock.
ccooper21
2016-09-16 18:30
I was following the instructions for the block-listener example. This is the command line I used to instantiate the first docker container: `docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT=true -e CORE_PEER_VALIDATOR_CONSENSUS_PLUGIN=pbft hyperledger/fabric-peer peer node start`
ccooper21
2016-09-16 18:31
What is supposed to be listening on port 2375? Is that docker itself? Maybe I need start some service on my docker host?
garisingh
2016-09-16 18:31
docker daemon
garisingh
2016-09-16 18:31
you need to pass the `-H ` argument when you start the daemon

@ccooper21 what version of docker are u using? Can u try the following configuration? it works from Docker 1.9.0 ~ 1.12.1 in my local environment. DOCKER_OPTS="$DOCKER_OPTS -H -H unix:///var/run/docker.sock --api-cors-header='*' "
ccooper21
2016-09-17 00:31
Docker v1.12.1. I am using the Vagrant/devenv scripts to set everything up but trying to run in an AWS EC2 VM. The problem I seem to be having is that the scripts update the kernel, and afterwards once I reboot Docker is broken. Docker works okay once the setup is complete as long as I don't reboot.
ccooper21
2016-09-17 00:41
@baohua Thanks for the suggestion though. I was able to start Docker with those settings but then got a build error when running the tests. I wasn't sure if it might be due to leaving off the `-s aufs` Docker option.

@ccooper21: please feel free to file a jira and submit a patch. It isn't a requirement to file a jira, but it does help us track things. LMK if you need any help with this.

I'll have a component added to JIRA

Are there any docs for installing the `peer` tool locally? Seems like there is some lightly fiddly rocksdb linking and versioning issues for me on OS X.
donovanhide
2016-09-17 14:23
Also, does anyone have some opinions on distributing a developer environment as a docker image as well as a vagrant one? Seems quite long-winded to have both Docker and Vagrant installed :slightly_smiling_face:
donovanhide
2016-09-17 14:34
Ahh, nevermind can just ```docker exec -it ripplelike_vp0_1 bash```
donovanhide
2016-09-17 14:50
Actually, it would be useful to have a local (non-docker and non-vagrant) `peer` command available. Is this an easy possibility?
cbf
2016-09-17 16:00
it can be built on mac, have not tried windoze
cbf
2016-09-17 16:00
if you dig in the docs, there's info on how to build on macosx
cbf
2016-09-17 16:01
you can use docker for mac or windows which is pretty light weight
mart0nix
2016-09-17 17:13
@cbf any luck with the dev environment? I also had problems with Docker on Mac and I had to install the beta branch before Docker worked on my Mac
donovanhide
2016-09-17 18:19
@cbf On OS X I followed:
https://github.com/hyperledger/fabric/blob/master/docs/dev-setup/build.md#building-natively-on-osx
but got:
```$ make peer
Building docker base-image
BUILD-CACHE: exists!
stdin: is not a tty
Sending build context to Docker daemon 11.78 kB
Error response from daemon: ENV must have two arguments
make: *** [build/image/base/.dummy] Error 1```
Also feels like there is a need for a lightweight API client in Go, which doesn’t have the rocksdb dependency?
cbf
2016-09-17 18:20
I agree, and I am working on that
cbf
2016-09-17 18:20
still having issues with docker 1.12.1
cbf
2016-09-17 18:21
I may try backing off to 1.12 beta
donovanhide
2016-09-17 18:22
I’ve happily been running the docker images for the peer and membersvc elements, it’s just for developing chaincode locally and then deploying that I need a CLI client. `peer` seems to be the only one available in Go so far, is that the case?
mart0nix
2016-09-17 18:22
@donovanhide the SDK is coming out soon
mart0nix
2016-09-17 18:23
@cbf try the beta channel
donovanhide
2016-09-17 18:24
@mart0nix Great! Will that turn up as a separate repository, or be embedded in the fabric repo?
donovanhide
2016-09-17 18:25
Would be keen to beta test if possible!
cbf
2016-09-17 18:26
the sdk with v0.6 is available, (npm install hfc) but it is also being refactored
donovanhide
2016-09-17 18:27
Kind of just looking for a Go CLI tool for invoking and deploying chaincode. A `peer`-lite I guess… Is that something I could help with?
donovanhide
2016-09-17 18:29
Just trying to build a workflow for myself and colleagues that doesn’t involve more than just Go and Docker.
mart0nix
2016-09-17 18:29
@cbf the HFC will be able to function outside of vagrant environment right ?
cbf
2016-09-17 18:32
yes
cbf
2016-09-17 18:33
@donovanhide I have been working on teasing out the cli function from peer
donovanhide
2016-09-17 18:33
@cbf that sounds great!
cbf
2016-09-17 18:33
have not yet pushed to Gerrit, but I can prob get that this weekend
donovanhide
2016-09-17 18:34
No rush at all, as long as I know which repo to monitor.
donovanhide
2016-09-17 18:38
A bit of feedback on the Go directory structure. It would be fantastic to be able to just `go get http://github.com/hyperledger/fabric/peer` and that builds the binary. The repo seems quite full of Docker and Vagrant image creation tools and scripts which perhaps should live in a separate repo that makes use of the main one?
donovanhide
2016-09-17 18:38
I know it gets complicated with vendoring :slightly_smiling_face:
cbf
2016-09-17 18:40
yeah, the vendoring is the messy part
cbf
2016-09-17 18:41
the package organization is a bit tangled
cbf
2016-09-17 18:41

cbf
2016-09-17 18:41
I have not yet got it building stand-alone without rocksdb
cbf
2016-09-17 18:41
but I do have it built on mac
donovanhide
2016-09-17 18:43
Yep, rockdb is a big old dependency :slightly_smiling_face:
donovanhide
2016-09-17 18:43
Did you use homebrew rocksdb?
mart0nix
2016-09-17 18:46
@cbf is this the only available example of the SDK outside of Vagrant?: https://github.com/hyperledger/fabric/blob/master/docs/nodeSDK/sample-web-app.md
cbf
2016-09-17 18:54
@mart0nix ok, getting closer
cbf
2016-09-17 18:54
I had an earlier version of that compose running - I just ran it again with latest build
cbf
2016-09-17 18:54
now just need to fix what’s wrong with the published document
cbf
2016-09-17 18:55
@mart0nix you can run that sample in or outside vagrant (once I get it working)
mart0nix
2016-09-17 18:56
awesome
mart0nix
2016-09-17 18:56
@cbf you mean the compose file here: https://github.com/hyperledger/fabric/blob/master/docs/nodeSDK/node-sdk-self-contained.md

2016-09-17 23:02
cbf
2016-09-17 23:02
I pushed the fixes to my personal repo

Just try to create the blockchain service again tomorrow or in half a day. Once you have it created don’t throw it away (like I did) otherwise you might again risk of not being able to create it for a while.
mart0nix
2016-09-18 10:49
after spending a month with Bluemix I'd suggest people look into local deployment options
mart0nix
2016-09-18 10:49
until it gets more production ready
mart0nix
2016-09-18 11:03
@cbf I pulled the repo but I get the following error when I do docker-compose up

may be the image should be set to image: hyperledger/fabric-sdk (instead of just fabric-sdk)
cbf
2016-09-18 11:05
you need to build the docker image first
cbf
2016-09-18 11:05
docker build -t fabric-sdk:latest .
cbf
2016-09-18 11:08
ok, just checked - (need more coffee;-) you just need to build the docker image first as noted above
cbf

@mart0nix ^^

garisingh
2016-09-18 11:18
I just built in on my Mac with no issues
garisingh
2016-09-18 11:18
perhaps you need to cleanup your fabric images?
grapebaba
2016-09-18 11:19
@mart0nix: usUally i use loCal, but i need do a demo for customer using blUemix
garisingh
2016-09-18 11:19
you might want to do a `docker pull hyperledger/fabric-peer:latest`
garisingh
2016-09-18 11:20
@grapebaba - team is working on adding more networks for BMX so stay tuned on that front
mart0nix
2016-09-18 11:33
@garisingh where is that hardcoded GOPATH /opt/gopath/ coming from in the docker build process ?
mart0nix
2016-09-18 11:36
@cbf any idea on the Step 7 : RUN cp $GOPATH/src/github.com/hyperledger/fabric/examples/sdk/node/* .
---> Running in de2cc651d065
cp: cannot stat '/opt/gopath/src/github.com/hyperledger/fabric/examples/sdk/node/*': No such file or directory
garisingh
2016-09-18 11:38
it will be the GOPATH set inside the container
garisingh
2016-09-18 11:38
in this case, your base image is `hyperledger/fabric-peer:latest`
garisingh
2016-09-18 11:40
try this:
`docker run --rm -it hyperledger/fabric-peer /bin/bash`
mart0nix
2016-09-18 11:41
ok that worked
garisingh
2016-09-18 11:42
`ls $GOPATH/src/github.com/hyperledger/fabric/examples/sdk/node`
mart0nix
2016-09-18 11:42
ls: cannot access /opt/gopath/src/github.com/hyperledger/fabric/examples/sdk/node: No such file or directory
mart0nix
2016-09-18 11:42
aha I didn't realize Docker will have its own GOPATH var
garisingh
2016-09-18 11:43
fabric-peer sets GOPATH
garisingh
2016-09-18 11:43
so I think you just need to pull down an updated fabric-peer image
garisingh
2016-09-18 11:43
`docker pull hyperledger/fabric-peer:latest`
mart0nix
2016-09-18 11:43
well I already have the latest fabric-peer image
mart0nix
2016-09-18 11:44
wouldn't it make more sense to set my own GOPATH inside Docker ?
garisingh
2016-09-18 11:45
```
Garis-MacBook-Pro:~ gsingh$ docker run --rm -it hyperledger/fabric-peer /bin/bash
root@49f290c16fd7:/opt/gopath/src/github.com/hyperledger/fabric#
root@49f290c16fd7:/opt/gopath/src/github.com/hyperledger/fabric#
root@49f290c16fd7:/opt/gopath/src/github.com/hyperledger/fabric#

root@49f290c16fd7:/opt/gopath/src/github.com/hyperledger/fabric#
```
garisingh
2016-09-18 11:45
so my fabric-peer has the `$GOPATH/src/github.com/hyperledger/fabric/examples/sdk/node/` directory
garisingh
2016-09-18 11:46
and it seems yours does not?
mart0nix
2016-09-18 11:47
ok let me try that then
donovanhide
2016-09-18 12:27
Does the `peer` binary running in this image:
https://hub.docker.com/r/hyperledger/fabric-peer/
actually require any of the files in gopath/src/github.com/hyperledger/fabric to operate? I know it is quite convoluted, but previously I’ve use docker images to create binaries and then delete all the source directory files and build tools. Makes for compact docker images and ensures that all configuration is passed through the docker or kubernetes config methods.
donovanhide
2016-09-18 12:28
My aim is to have a repeatable workflow for bringing up a group of validators for internal testing, running on Google Cloud.
garisingh
2016-09-18 12:37
@donovanhide - for running the peer and membersrvc processes in Docker containers you should not actually need the fabric source or the Go compiler in those images. The one caveat with the peer is that if you want to support deploying chaincode via the REST API and using remote Git repositories, then you would need the Go compiler and further if you did not vendor the fabric shim with your chaincode in that remote repo you'd also need the fabric source
garisingh
2016-09-18 12:38
BUT - if you are willing to stick with deploying chaincode from your local filesystem using the NodeSDK, then you could have a pretty minimal peer image
garisingh
2016-09-18 12:40
so I've basically built binary peer and rocksdb and then just copied into base alpine image
garisingh
2016-09-18 12:41
makes for a nice compact image
garisingh
2016-09-18 12:41
(well I did it a while back - have not update in a while)
donovanhide
2016-09-18 12:41
Yes, we’d want to compile all chaincode locally first during the testing phase. Would also like to remove the dependency for any node.js if possible. In an ideal world we’d also have a local `chaincode` tool written in Go that does the deploy, invoke and query functions that we can use in our dev workflow, which lacks the rocksdb dependency.
donovanhide
2016-09-18 12:42
Do you still have a Dockerfile for that minimal alpine image you made?
donovanhide
2016-09-18 12:44
Our basic use case at the moment is just to allow developers, using just Docker for Mac and Go to play around with an internal fabric environment running on Google Cloud. It gets complicated getting people to learn a bit of node.js and vagrant as well :slightly_smiling_face:
garisingh
2016-09-18 12:49
garisingh
2016-09-18 12:50
I was a bit lazy in that I never added in actually building the binaries into this workflow, but basically the stuff in `bin` and `lib` just came from copying the binaries from the host system. Just need to make sure to build rocksdb with the portable flag
garisingh
2016-09-18 12:50
but I think you'll get the idea.
donovanhide
2016-09-18 12:51
Thanks that looks like a good starting point, much appreciated. I’ll share any Dockerfile that I get working!

Have just been reading through the consensus docs, specifically the endorsement stage :
https://github.com/hyperledger/fabric/blob/master/proposals/r1/Next-Consensus-Architecture-Proposal.md#23-an-endorser-receives-and-endorses-a-transaction
Given that the transaction simulation stage runs on both the submitting peer and the endorsing peers and transactions are not broadcast as a batch, I’m wondering how this design will deal with highly contended keys in the value store. For example, say the ledger is used by the chaincode to hold an orderbook, with offers constantly changing at high frequency. It is likely that clients will be submitting to different peers at around the same time transactions that will modify the tip of the orderbook. My reading of the design document is that this will frequently lead to the `STALE_VERSION` endorsement being returned.
Ripple’s approach to this issue is to group a set of transactions into a batch which are processed in a hard to predict determinisitc order and loose time constraints dictate which transactions get into which batch. I’d be very interested to hear any views on this potential issue :slightly_smiling_face:
donovanhide
2016-09-18 15:30
https://github.com/hyperledger/fabric/blob/master/proposals/r1/Next-Consensus-Architecture-Proposal.md#41-batch-and-block-formation discusses this a little, but it seems that the batching occurs after endorsement?

mart0nix
2016-09-18 16:27
I'm not sure what the fabric-baseimages are
mart0nix
2016-09-18 16:27
in general there are 3 images you need before you do a full stack development
mart0nix
2016-09-18 16:27
peer which is the node for a lack of a better word
mart0nix
2016-09-18 16:28
the membersrv which is like 3rd party services like certificates
mart0nix
2016-09-18 16:28
and the nodesdk which is the SDK that will let you actually write an app that communicates with a chaincode
mart0nix
2016-09-18 16:31

mart0nix
2016-09-18 16:43
this sounds like some kind of a routing/mapping issue
cbf
2016-09-18 16:48
you are running this inside vagrant? @mart0nix
mart0nix
2016-09-18 16:48
no
cbf
2016-09-18 16:49
you are on docker 1.12.1?
cbf
2016-09-18 16:49
mac, windows or linux
cbf
2016-09-18 16:49
ah mac
mart0nix
2016-09-18 16:49

mart0nix
2016-09-18 16:49
btw: I'm looking at the docker compose
mart0nix
2016-09-18 16:49
under nodesdk:

mart0nix
2016-09-18 16:50
shouldn't I comment out the second line ?
cbf
2016-09-18 16:50
should be one line
mart0nix
2016-09-18 16:50
yeah I mean swap them
mart0nix
2016-09-18 16:51
comment the first one and comment out the second
cbf
2016-09-18 16:52
ok, I see - yes, the chaincode was not deployed
cbf
2016-09-18 16:53
you can do that a couple of ways
cbf
2016-09-18 16:53
you can swap the bash for the commented command line
mart0nix

mart0nix
2016-09-18 16:53
looks like that solved the problem
mart0nix
2016-09-18 16:54
however in my docker logs I still see the following line:

cbf
2016-09-18 16:54
will update
mart0nix
2016-09-18 16:54
it looks like the chaincode went through though
cbf
2016-09-18 16:57
sorry for the hassle… I have a patch in review that addresses this in fabric and will deploy new official images for v0.6
cbf
2016-09-18 16:57
thanks for your perseverence
mart0nix
2016-09-18 16:59
hey no worries
mart0nix
2016-09-18 16:59
I'm glad to help out
mart0nix
2016-09-18 17:00
another issue is that the whole container situation is crashing after a minute or two

@cbf thanks for all the help !!!
donovanhide
2016-09-18 19:22
There’s some gnarly hard-coded paths that don’t play well with minimal docker images:
https://github.com/hyperledger/fabric/blob/master/consensus/pbft/pbft.go#L80
garisingh
2016-09-18 19:25
@donovanhide - that's actually OK - if you notice that's just one of the entries appended to the of places to search for the config file
garisingh
2016-09-18 19:26
if you notice in the Dockerfile I pinged you, I actually store those configs at `../consensus` relative to the bin directory
garisingh
2016-09-18 19:27
you can also keep the config files in the same dir as the binaries
donovanhide
2016-09-18 19:28
Yep, fair enough, just running into all the config files one by one :slightly_smiling_face: Trying to also achieve minimal Dockerfile length as well :slightly_smiling_face:
```# minimal fabric
FROM golang:alpine
RUN apk add --virtual .build-dependencies git g++
RUN apk add rocksdb-dev --update-cache --repository http://nl.alpinelinux.org/alpine/edge/testing
RUN go get http://github.com/hyperledger/fabric/peer
RUN apk del .build-dependencies ```
donovanhide
2016-09-18 19:28
Who’s the best person to discuss consensus with?
garisingh
2016-09-18 19:30
the #fabric-consensus-dev channel is actively monitored by the folks who wrote consensus
donovanhide
2016-09-18 19:31
cool, thanks :slightly_smiling_face:
abutler
2016-09-18 19:42
has joined #fabric
donovanhide
2016-09-18 19:45
It’s a little bit inconsistent that the config search path for the consensus config yaml files goes up a directory and then down two directories, while the peer config file should be in the same directory as the binary. With kubernetes you’d tend to want to put all config files in /etc/peer/[core.yaml|pbft.yaml|noops.yaml] for example. Would make it easier to map a directory of configuration files per node.
donovanhide
2016-09-18 19:49
https://github.com/hyperledger/fabric/blob/master/consensus/pbft/pbft.go#L73
If this was `config.SetConfigName(“pbft”)` and `config.yaml` was renamed `pbft.yaml`, and the same for noops, it would be more flexible. Otherwise, you can’t have all the config files in one directory.

is there someway i can deployed on 4 Host
grapebaba
2016-09-19 10:26
@garisingh: i got an ibm_db issue when deploy an B2BPOC demo
grapebaba
2016-09-19 10:27
i guess maybe BMX node version is high
mart0nix
2016-09-19 13:00
is there an old school way of building a hyperledger environment? like downloading and compiling the different pieces instead of working with docker and vagrant ?
ghaskins
2016-09-19 13:03
@mart0nix: short answer: yes
ghaskins
2016-09-19 13:03
Long answer: you always need docker as this is what the peer uses for chaincode
mart0nix
2016-09-19 13:05
well the peer is a stand-alone piece of software
mart0nix
2016-09-19 13:05
and the chaincode gets sent to the network
mart0nix
2016-09-19 13:05
what's the need for docker ?
mart0nix
2016-09-19 13:06
@ghaskins I may be missing something : ))
ghaskins
2016-09-19 13:07
Hold on, kid potty emergency
ghaskins
2016-09-19 13:12
@mart0nix: chaincode is compiled and executed in a docker container
ghaskins
2016-09-19 13:12
The peer drives the docker API
mart0nix
2016-09-19 13:13
I see
mart0nix
2016-09-19 13:15
@cbf: deployRequest.chaincodePath = "http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02";
mart0nix
2016-09-19 13:16
could that be a local path or it needs to be a github repo ?
mart0nix
2016-09-19 13:16
I'm looking at the node app
ghaskins
2016-09-19 13:16
but if you want to create an environment similar to what the official devenv uses you can start with a base 14.04 image and run the following scripts
ghaskins
2016-09-19 13:17
ghaskins
2016-09-19 13:18
ghaskins
2016-09-19 13:18
this also works (with minor adjustments) for 16.04
ghaskins
2016-09-19 13:18
(the official image uses 14.04 currently, though we hope to upgrade this ASAP)
mart0nix
2016-09-19 13:19
got it
mart0nix
2016-09-19 13:19
thanks!
ghaskins
2016-09-19 13:19
np
mart0nix
2016-09-19 13:44
@ghaskins btw do you know where I can find output from the chaincode
mart0nix
2016-09-19 13:44
fmt.Printf("Aval = %d, Bval = %d\n", Aval, Bval)
mart0nix
2016-09-19 13:44
where would that show up ? : ))
ghaskins
2016-09-19 13:44
otp
mart0nix
2016-09-19 13:45
output ?
ghaskins
2016-09-19 13:45
on the phone
mart0nix
2016-09-19 13:45
oh ok : ))
ghaskins
2016-09-19 13:45
sorry, answer in a bit
mart0nix
2016-09-19 13:45
no worries
mart0nix
2016-09-19 13:46
ok so if anyone else can answer the logging questions
mart0nix
2016-09-19 13:47
basically where does the output from the fmt goes
mart0nix
2016-09-19 13:47
as well as the logging provided by the shim logger
cbf
2016-09-19 13:54
logging goes to stdout and stderr - it can be configured to write to syslog etc, if I am not mistaken
cbf
2016-09-19 13:55
the fmt statements I believe write to stdout unless they are creating an error
ghaskins
2016-09-19 13:56
back
cbf
2016-09-19 13:56
there are discussion threads on rethinking error handling and logging in slack and elsewhere
ghaskins
2016-09-19 13:56
i know that from the perspective of chaincode itself…it just does pure stdout/stderr printing as @cbf mentioned…when you run in devmode, this is exactly what you see
ghaskins
2016-09-19 13:57
when in netdeploy mode, I am not sure where the stdout is routed to
ghaskins
2016-09-19 13:57
@muralisr might know
cbf
2016-09-19 13:57
@garisingh might share what he has done for Bluemix
cbf
2016-09-19 13:58
I believe he is rotating logs presently… not sure that he is pulling them off or not
mart0nix
2016-09-19 14:01
so I'm running @cbf example of a self-contained node app (which is using this chaincode: https://github.com/hyperledger/fabric/blob/master/examples/chaincode/go/chaincode_example02/chaincode_example02.go)
mart0nix
2016-09-19 14:01
I see line 119: fmt.Printf("Aval = %d, Bval = %d\n", Aval, Bval)
mart0nix
2016-09-19 14:01
I can't figure out where would that get logged to
mart0nix
2016-09-19 14:02
the SDK deploys the chaincode so it's unclear where is the stdout/stderr from that point on : ))
ghaskins
2016-09-19 14:04
@mart0nix it relates to what I was talking about earlier: the peer(s) will compile/launch the submitted code inside a docker container
ghaskins
2016-09-19 14:04
so “stdout” would be w.r.t. that docker container running on each peer
ghaskins
2016-09-19 14:05
when you perform a standard deployment (vs a devmode deployment) the peer is going to manage where it maps that containers stdout
mart0nix
2016-09-19 14:05
well that's what I thought too
ghaskins
2016-09-19 14:05
via a mechanism I am not familiar with
mart0nix
2016-09-19 14:05
but I'm looing at docker logs -f peer
mart0nix
2016-09-19 14:05
and I can't find any output from the chaincode there
mart0nix
2016-09-19 14:05
I'm set at DEBUG level
ghaskins
2016-09-19 14:06
@muralisr is really the one who would know for sure
ghaskins
2016-09-19 14:06
do note that this wouldnt be the peer container though
ghaskins
2016-09-19 14:06
the chaincode instances each have their own
muralisr
2016-09-19 14:09
@ghaskins _so “stdout” would be w.r.t. that docker container running on each peer_ that’s correct for the chaincode container
muralisr
2016-09-19 14:10
(if I understood you correctly)
mart0nix
2016-09-19 14:12
well I'm running 3 containers - peer, membersrv and nodesdk
muralisr
2016-09-19 14:12
and when the peer starts a chaincode, its going to run in a container. The stdout for that container will contain the chaincode logs
ghaskins
2016-09-19 14:12
@muralisr yes, i think that is what @mart0nix is asking about
ghaskins
2016-09-19 14:13
im not clear what, if anything, we do with stdout as I always run devmode
mart0nix
2016-09-19 14:13
@muralisr so docker logs -f peer
mart0nix
2016-09-19 14:13
should show me output from the chaincode itself ?
muralisr
2016-09-19 14:15
@mart0nix I do `docker ps` to get my <cc container id> and then do `docker logs <cc container id>`
ghaskins
2016-09-19 14:16
@muralisr if we dont already have it, or have plans for it, we should probably create a JIRA to add a feature to allow the chaincode logs to be aggregated as part of the UX
mart0nix
2016-09-19 14:17
@muralisr that's what I thought but I don't see the output from the chaincode there : ))
mart0nix
2016-09-19 14:18
may be I'm missing something - I will give it another try
mart0nix
2016-09-19 14:18
at least I know where to look for it : ))
mart0nix
2016-09-19 14:18
@ghaskins that would be awesome
mart0nix
2016-09-19 14:19
from a beginner's perspective, being able to log and debug is very useful
ghaskins
2016-09-19 14:19
@mart0nix could you write one up?
ghaskins
2016-09-19 14:19
doesnt have to be elaborate, just so we have a placeholder minimally
ghaskins
2016-09-19 14:20
but should proabably wait to hear from @muralisr as for all I know there are plans in the works
mart0nix
2016-09-19 14:20
@ghaskins I'm not a great programmer, I'm more of a hacker : ((
ghaskins
2016-09-19 14:21
I just meant the JIRA
mart0nix
2016-09-19 14:21
oh I see - I thought you mean If I could write a logging module or something : ))
ghaskins
2016-09-19 14:21
if you wanted to, thats great and would be welcome…but I was just referring to getting something into JIRA so we dont lose it
mart0nix
2016-09-19 14:22
oh that would be great
mart0nix
2016-09-19 14:22
what's the JIRA link
ghaskins
2016-09-19 14:22
under FAB
mart0nix
2016-09-19 14:22
ok
mart0nix
2016-09-19 14:22
well I found a logging tab in Bluemix
mart0nix
2016-09-19 14:23
but it's not very functional for some reason (it's rather slow, hard to navigate, etc...)
mart0nix
2016-09-19 14:26
@mart0nix uploaded a file: https://hyperledgerproject.slack.com/files/mart0nix/F2D6JV7ME/screen_shot_2016-09-19_at_5.25.18_pm.png and commented: logging options
ghaskins
2016-09-19 14:26
Personally I think the chaincode logging needs to be a first-class exposed feature of the fabric itself
mart0nix
2016-09-19 14:32
well the shim ChaincodeLogger is a great idea
mart0nix
2016-09-19 14:33
it needs a few different log handlers so you can put logs in syslog, queues, 3rd party aggregators, etc...
mart0nix
2016-09-19 14:33
it could also be used for monitoring and alerting
mart0nix
2016-09-19 14:33
for level WARN and ERR
mart0nix
2016-09-19 14:35
you set the logging levels for the different environments (production, development, staging, etc...) and it's all tip top
cbf
2016-09-19 14:35
@ghaskins someone tried a patchset for that but it was a bit entangled so I think it is undergoing a rethink
ghaskins
2016-09-19 14:35
@cbf ah, cool, glad its being worked on at least
cbf
2016-09-19 14:35
some of us were also looking at 3rd party log packages
cbf
2016-09-19 14:36
the config (viper) and standard go-logging are somewhat inadequate
ghaskins
2016-09-19 14:36
if there is some kind of jira/thread for this conversation you could point @mart0nix at, please let him know.
ghaskins
2016-09-19 14:38
ty
mart0nix
2016-09-19 14:41
awesome - I will look around Jira and see if I can be of any help
mart0nix
2016-09-19 15:03
on a different note
mart0nix
2016-09-19 15:03
can anyone enlighten me how to load a local chaincode via the SDK
mart0nix
2016-09-19 15:03
deployRequest.chaincodePath = "http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02";
mart0nix
2016-09-19 15:04
could that be a local chaincode or it can fetch it from github ?
muralisr
2016-09-19 15:20
@mart0nix since `http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02` will resolve to the chaincode GO package on the peer filesystem, that path cannot be downloaded from the network… however `deployRequest.chaincodePath = “https://github.com/mart0nix/fabric/examples/chaincode/go/chaincode_example02` can
mart0nix
2016-09-19 15:21
@muralisr got it. Thanks!
muralisr
2016-09-19 15:21
sure thing!
mart0nix
2016-09-19 15:28
@muralisr for some reason I still can't get any chaincode log records to show in the peer logs
mart0nix
2016-09-19 15:30
I have this record in func (t *SimpleChaincode) Init..........
mart0nix
2016-09-19 15:30
logger.SetLevel(shim.LogInfo) in main()
mart0nix
2016-09-19 15:30
it looks like the chaincode is deployed successfully and yet not log record is being produced
mart0nix
2016-09-19 15:31
I must be missing something huge here
muralisr

oops :slightly_smiling_face:
muralisr
2016-09-19 15:34
@mart0nix _I still can't get any chaincode log records to show in the peer logs_ - they won’t show up in the peer logs
muralisr
2016-09-19 15:36
(maybe I misunderstood the above) … if you do docker ps, you should should see peer and chaincode containers. I’d expect the chaincode container to contain the logs
mart0nix
2016-09-19 15:37
@muralisr I have 3 containers: peer, membersrv and nodesdk
mart0nix
2016-09-19 15:37
I'm deploying via the SDK
mart0nix
2016-09-19 15:37
the nodesdk container doesn't have ANY logs in it
mart0nix
2016-09-19 15:38
logging level is set to debug in the docker-compose file

after you do deploy can you show `docker ps`
mart0nix
2016-09-19 15:41
still those three containers
mart0nix
2016-09-19 15:41
same deal if I deploy on the command line

If you are not deploying from command line, I’d expect to see a chaincode container started by the peer
mart0nix
2016-09-19 15:55
aah may be the node app does create a container but it quickly exists
cbf
2016-09-19 15:55
@mart0nix on the question of chaincode and sdk, presently it needs to be local. There is work on adding git
mart0nix
2016-09-19 15:55
so I'm not able to see new container because it comes and goes quickly
mart0nix
2016-09-19 15:56
@cbf got it
mart0nix
2016-09-19 15:56
I will start a run loop and see if things change
mart0nix
2016-09-19 15:57
but the bottom line is that a chaincode will always run in a new container that I should be able to see with docker ps
mart0nix
2016-09-19 15:57
correct ?
cbf
2016-09-19 15:59
@mart0nix it shouldn’t disappear
cbf
2016-09-19 15:59
so, if you are running my sample, the chaincode is the nodeSDK container
cbf
2016-09-19 16:00
if you ran docker-compose -d, then you can see the chaincode logs with:
cbf
2016-09-19 16:00
docker logs nodeSDK
cbf
2016-09-19 16:00
the sample I shared is running in -chaincode-dev mode
cbf
2016-09-19 16:01
in this mode, we start the chaincode directly and it connects to the peer
cbf
2016-09-19 16:01
in normal operations, you would not no this
cbf
2016-09-19 16:01
recall that I had the command for the nodeSDK containeer as ‘bash’ at one point?
cbf
2016-09-19 16:01
try doing that
cbf
2016-09-19 16:02
then, after you docker exec into the nodeSDK container, start the chaincode_example02 using the same command as in the docker-compose now - run in the background so that you can then run the node app
cbf
2016-09-19 16:03
alternately, you can run the runme.sh script and it will do all that for you
mart0nix
2016-09-19 16:31
@cbf got it - let me try doing that
mart0nix
2016-09-19 17:28
@cbf it worked as expected
mart0nix
2016-09-19 17:29
the logs are now showing up when I started the chaincode on the command line
mart0nix
2016-09-19 17:29
my mistake was that I was trying to deploy the chaincode first via the docker-compose file and then via the SDK itself
mart0nix
2016-09-19 18:15
awesome stuff @cbf @muralisr @ghaskins thanks for all the help - I'm able to do chaincode development now !!!

@satheesh Thanks for your response. I will take a look at it
garisingh
2016-09-21 08:51
@david.acton - sorry for the late response. looks like you were only running 2 peers so you'd be running in NOOPS consensus mode. In this mode, while you technically you can add another peer after the fact, it will actually not receive any of the transactions which were executed on the other peer prior to it connecting. Deploying chaincode is a transaction so the second peer would not have received the deploy and therefore would not have the chaincode deployed
garisingh
2016-09-21 08:53
@joseph -
```
Is it possible to run a memberservices on one host and fabric-peers on another hosts without Swarm or Kubernetes or so on?
```
garisingh
2016-09-21 08:55
this is definitely possible. I'll assume you are running the the peer and member services in Docker containers. The key is that you'll need to make sure you expose the ports on the routable IPs for each node and then you can just wire things together as usual using the IP addresses
arvin
2016-09-21 08:55
@cbf hi, if chaincode docker container down,how can i recorvery it ?
garisingh
2016-09-21 09:03
@arvin - you should only need to run another invoke or query transaction and the peer should create and start the container (if the container is down it basically removes the previous instance and creates and starts a new one)
arvin
2016-09-21 09:05
@garisingh thank you
david.acton
2016-09-21 09:09
@garisingh Hi, thanks for the response!!! You are absolutely correct, I am running two nodes in noops mode. That’s a shame that it doesn’t sync. It makes testing hard. Can you point me to the docs which explains this so I can set up correctly?

garisingh
2016-09-21 09:17
@david.acton - if you start the two node first and make sure they connect prior to deploying your chaincode, then things will work in NOOPS mode. But there's no guarantees that nodes in NOOPS mode will stay in sync. For multiple to nodes to stay in sync, you'll want to run PBFT and you would want to run 4 nodes. In the `bddtests` folder you can find some sample docker compose files for getting a 4 peer PBFT network up and running
david.acton
2016-09-21 09:21
@garisingh That’s great to know. I can get the nodes setup. How is one supposed to know this? did I miss some reading?
garisingh
2016-09-21 09:32
I wouldn't say you missed some reading but if you check out http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Network-setup/ and scroll down there's a small section titled consensus which gives a quick explanation of NOOPs but probably not enough about what it really means

Yes, this could use some (more, much more!) clarification...
jonathanlevi
2016-09-22 17:23
@mart0nix: when people refer to bindings in this context (at least when the initial spec was written) they usually refer to the naming of transactions...
jonathanlevi
2016-09-22 17:24
So that a transaction with a (unique) name can be referred to, e.g. for data to be exchanged...
jonathanlevi
2016-09-22 17:24

2016-09-22 17:34
:wink:
jonathanlevi
2016-09-22 17:35
Let’s me try to sum it up in a few lines…
jonathanlevi
2016-09-22 17:35
First, let’s take a step back:
The feature effectively allows one a bit of a finer-grained way of access-control. E.g., allowing a specific user, say ‘Bob’ to execute a specific (named) transaction.
jonathanlevi
2016-09-22 17:36
-----
Assume that this is the case, and that Alice has ‘granted’ or ‘allowed’ Bob to execute such a transaction (when she, Alice, deployed that transaction):
-----
jonathanlevi
2016-09-22 17:37
In order for Bob to execute this transaction, using its name (binding)…. Bob need to sign it.
jonathanlevi
2016-09-22 17:37
And the checking is whether or not it is indeed Bob who is trying to execute it.
jonathanlevi
2016-09-22 17:38
The mechanism relies on PKI (specifically, Bob needs to prove that he is Bob)
jonathanlevi
2016-09-22 17:38
It is done by Bob needing to sign the transaction name/binding + the passed arguments using his private key.
jonathanlevi
2016-09-22 17:40
So using the CertificateHandler for his cert (E/TCert)… and the TransactionHandler (for obtaining the bindings of that transaction… Bob generates/creates a signature, using his private key…. and encloses it, as an argument, with a subsequent call to `NewChaincodeExecute()`
jonathanlevi
2016-09-22 17:41
-----
[ So now that we know that :disappointed: and I do not really know if this was documented, or not, tbh ],
jonathanlevi
2016-09-22 17:42
` // metadata contains the signature under the signing key corresponding`
- is that signature that Bob provided
jonathanlevi
2016-09-22 17:42
`// verification key inside certificate of the payload of the transaction`
- this is the public key
jonathanlevi
2016-09-22 17:43
(that is in the E/TCert)
jonathanlevi
2016-09-22 17:44
`// payload of the transaction (namely, function name and args) and the transaction binding (to avoid copying attacks)`
- is indeed the function name, actual args and the actual bindings.

affiliations could be used as Tcert attributes to provide further control lists based not just on roles but also affiliations ?
mart0nix
2016-09-22 21:08
@jonathanlevi ?
mart0nix
2016-09-22 21:14
also "aca" stands for "Attribute Certificate Authority"
mart0nix
2016-09-22 21:14
but what does "eca" stand for ?
nickgaski
2016-09-22 21:19
eca - enrollment cert authority tca - transaction cert authority

Some have asked about where to find backlog proposals from IBM contributors. To find proposed backlogs take a look at the public boards that were created for various components such as ledger, consensus, endorser, etc. Each will contain the current thinking of backlog and current thinking relative to priorities. We would like feedback and if there are user stories or tasks that look interesting please jump in.
mart0nix
2016-09-22 21:25
so @nickgaski is it fair to say that affiliations are Ecert attributes as oppsoed to Tcert attributes ?
nickgaski
2016-09-22 21:27
I would agree with that interpretation. If you look at the membersrvc.yaml you can see that enrollment can be curated to include a variety of features - amongst them, affiliations. However, with anything in the member services realm I would defer to Jonathan Levi

Wanted to add just one line up there: it’s better to treat/regard TCerts as the more public documents.
jonathanlevi
2016-09-22 21:30
The Enrollment/registration itself (these days) is still relatively more private than a TCert.
mart0nix
2016-09-22 21:30
@jonathanlevi got it - it does seem like you can enable encryption for Tcerts and their attributes
mart0nix
2016-09-22 21:31
btw I just found this for other who may be interested in this: https://github.com/hyperledger/fabric/blob/24c7483a2154df5a2d915b1a3b656e914cde7501/docs/tech/attributes.md
jonathanlevi
2016-09-22 21:32
Yes and no. (I am aware of this, thanks).
jonathanlevi
2016-09-22 21:33
I might not stay up much longer, but just quickly. The Attribute Encryption feature is disabled by default and can be enabled, but still, it has some limitations. Just a warning.
jonathanlevi
2016-09-22 21:34
The bootstrapping/the initial keys is something that requires taking care of, especially when working with containers. But, still, the EnrollmentID is still something that should be treated with caution, so it’s better to use the keys that are in your TCerts.
jonathanlevi
2016-09-22 21:36
[That was a v late night attempt of providing you with the right information, not too much details, while leaving you with actionable steps :wink: ]
mart0nix
2016-09-22 21:38
and is it possible to find linkability between Ecerts and Tcerts
mart0nix
2016-09-22 21:38
if yes - what are some strategies to prevent that?
jonathanlevi
2016-09-22 21:44
Many strategies (like key refresh, short sessions, sub account ID/aliases), but most importantly (and to be super direct and honest) Cryptographically, you’d need to have the Attribute Encryption working. Otherwise, it will indeed be possible to still link transactions...
jonathanlevi
2016-09-22 21:46
There was/is working in progress to enable this, but you should be aware of this, when/prior to breaking your “tasks” to blockchain transactions. It really depends on your cryptographic/business needs (e.g., anonymity? privacy? ….etc.)
jonathanlevi
2016-09-22 21:46
BTW: The last few pages, should have probably been asked in the #membership-services channel :wink:
mart0nix
2016-09-22 21:46
as of right now is Tcert attributes encryption working?

es, you can enable it. But as I said/wrote, it will still require some work in deployment… but yes, when we tested it on v0.5 it worked (keeping in mind that it was a new feature, etc. and the rest of the associated disclaimers).

muralisr
2016-09-25 13:38
@ccooper21 chaincode interactions are via requests to peer. There’s no direct call (http or otherwise) on the chaincode itself. Can you clarify _chaincode can be called using CORS_ ?
muralisr
2016-09-25 13:44
Perhaps you are asking about CORS with the REST calls ?

I'm working with a team to build a Hyperledger application at the Austin Blockchain Hackathon this weekend :slightly_smiling_face:
ccooper21
2016-09-25 14:38
We'd like to be able to call our chaincode across servers. So, that means calling the REST API endpoint for invoking chaincode (which I now realize is being serviced via the peer). So I guess my question should have been, does this endpoint support CORS? Or, asked another way is there a way to enable CORS for the peer?
ccooper21
2016-09-25 14:39
I don't know if it matters, but I'm running the peer in dev mode today since I am redploying code frequently, and ran into an issue deploying the code in production mode.

Are you running inside of vagrant or outside? If inside vagrant, it should pull down a version of RocksDB that is compatible the the vendored gorocksdb package. If outside, we should specify which version of RocksDB the peer is compatible with if we do not already.
If you really want to use an unsupported version of RocksDB, you could just manually replace the gorocksdb package in the vendor folder, but you may encounter other issues

@garisingh and one more thing when i am using /registrar api it is only giving loging functionality for already created users through membersrvc.yaml file is there any way we can create users when the fabric is in running mode through codes or api.
garisingh
2016-09-26 08:40
@ranjan008 - the NodeJS SDK allows you to create new users for membership services
garisingh
2016-09-26 08:41
it uses a GRPC-based API exposed by membership services directly
ranjan008
2016-09-26 11:03
@garisingh can we expect this feature to be there in RPC API anytime soon.
garisingh
2016-09-26 11:07
no. in order to create users you'll need to use the GRPC API provided directly by membership services rather than using an API through the peer

vzhou
2016-09-26 14:16

hmm, not sure how useful it would be in this case. It’s possible that some bug has been introduced.

I rebuild the membersrvc and run it
(I also start a new peer).
This works sometimes but now I keep receiving the following error
```{ Error: 'rpc error: code = 2 desc = Identity or token does not match.' }```
I understand that password in the yaml is view as a one-time, but I expect this be “reset” when I delete everything in production

I just saw in the docs that fabric leaves user authentication to application layer. In that case, I assume that the user authorization as well is outside the fabric's responsibilities. Does that mean chaincode should not use the user role while validating a data change?
venkat
2016-09-28 08:20
But I see the user roles in the memsrvc yaml file. So wondering how does fabric utilize the role information when it doesn't authenticate every user request?
garisingh
2016-09-28 08:53
@venkat - "application layer" includes chaincode. The fabric does a basic level of authentication / authorization whens security is enabled in that it checks for valid signatures and checks that certificates were issued by membership services. It also provides primitives for accessing the credentials (aka certificate) of the caller from within chaincode but it is up to the chaincode developer to create access control rules
Right now the "roles" provided by the fabric via membership services are only used in 2 ways:
- when a peer starts up as a validator there is a check to see that it was the right role
- when registering new users there is metadata which specifies which roles (if any) a user can register users as
venkat
2016-09-28 09:06
When a client applciation sends a REST invoke request after succesful login, the REST request itself is not carrying any identity info except for the securityContext attribute in the json data. How is the request authenitcated?
bfuentes
2016-09-28 09:07
Where can we find the roadmap of Blockchain service in Bluemix ? I just saw the v0.6.0 has being tagged to "developer-preview", does this mean that this will be deployed soon on Bluemix ? Thanks
garisingh
2016-09-28 09:08
@venkat - this is exactly why we want to move the REST interface out of the fabric peer itself and run it outside. Basically, think of the current REST interface as providing an interface to a "wallet" service provided by the peer
bfuentes
2016-09-28 09:10
The protocol still remain HTTP ? is swagger UI that will be moved out ?
garisingh
2016-09-28 09:10
@bfuentes - we typically try to update the BMX services to the latest release of the fabric within 3-4 weeks of the "final" release of a major version. There are still a few bugs in v0.6 which we are tracking to fix
venkat
2016-09-28 09:12
@garisingh - do you mean the request through hfc will carry identity info?
garisingh
2016-09-28 09:12
@bfuentes - pulling the REST interface outside the peer is slated for the v1.0 timeframe. Nothing will change for v0.5 / v0.6 . The reality is that there are 2 interfaces to the fabric today - one is REST (but as mentioned above this really ends up with a given peer acting as a client to the fabric on your behalf) and the other is GRPC (which you can interact with using the NodeSDK)
garisingh
2016-09-28 09:13
@venkat - hfc uses the native GRPC API which actually includes signing each transaction with the proper transaction certificate based on the user you choose to use
venkat
2016-09-28 09:16
So the request will carry a txn request signed using transaction certs. Does that help chaincode to extract user info from txn certs?

yes - and BTW - this is still the case when you use REST as well - basically the peer on which you invoke the REST API will sign transactions with the certs for the user specified in secureContext
garisingh
2016-09-28 09:18
there are methods within chaincode to extract the caller information
venkat
2016-09-28 09:20
Peer will sign in case of REST and nodeSdk/hfc will sign in case of GRPC?
garisingh
2016-09-28 09:21
With REST, the peer signs with the certificates of the user specified in secureContext (and uses the GRPC API to submit the transaction as well)
garisingh
2016-09-28 09:22
With GRPC directly, you actually have better control of the enrollment material for the users. In the case of REST, the enrollment material for the users you "login" are stored with the peer
venkat
2016-09-28 09:23
So in case of using node/hfc also, the signing actually happens at peer only, right? Or is it that signing is already done when the request reaches the peer?

when i am making a grpc call to membersrvc for registering a user i am getting this error
UNIMPLEMENTED: unknown service protos.ECAA
what am i doing wrong?
garisingh
2016-09-28 09:24
@venkat - with REST signing happens at the peer. With GRPC signing happens at the client prior to submitting to the peer
garisingh
2016-09-28 09:25
@ranjan008 - how are you calling membership services?

garisingh
2016-09-28 09:42
I have not looked at how Java generates GRPC stubs, but somehow there is a naming mismatch between the client and the server here

sukrith

any tips on how to go about testing chaincode written in go
sukrith
2016-09-28 15:14
is my only option
1. deploying a node locally
2. deploying the chaincode
3. invoking commands
4. monitoring the states
cbf
2016-09-28 17:14
@sukrith for _development_ of chaincode, use the —peer-chaincodedev flag when starting the peer, and you can run the chaincode yourself. This makes for a much easier dev-test-debug-repeat cycle as you don’t have to torture yourself searching for, and ssh’ing into the docker container running your chaincode.
cbf
2016-09-28 17:14
for use in a POC, you probably want the network mode, which starts with deploying the chaincode with the SDK.
cbf
2016-09-28 17:15
so yes, what you describe is correct, but for the iterative development process, —peer-chaincodedev mode is easiest to attach a debugger etc

sukrith
2016-09-28 21:14
it says peer not found
ccooper21
2016-09-28 21:42
@sukrith you need to set an environment variable that identifies the peer endpoint. so your deployment request would like something like:
```
CORE_PEER_ADDRESS=172.17.0.1:7051 peer chaincode deploy -l golang -n mycc -c '{"Function": "init", "Args": ["a","100","b","200"]}'
```

@ranjan008 - the only GRPC stuff in Java I know of is in the Java chaincode package. It uses GRPC to communicate with the peer - https://github.com/hyperledger/fabric/tree/master/core/chaincode/shim/java

Hi! I need some help in debugging the issue I am facing with my hyperledger block chain deployment. I have a hyperledger fabric deployment with 4 nodes (pbft consensus is enabled). I deployed a couple of smart contract and it worked fine for one day. But today when I am invoking smart contract I am noticing that the transaction is not getting distributed to all the peers and the transaction is never included in any block. In fact the block chain height is not changing at all! I looked at peer log and do not see any `ERR`. Only one peer to which I submitted the transaction shows these logs:
```
[2016-09-29 17:15:01+0000] 17:15:01.705 [devops] invokeOrQuery -> INFO 767a Transaction ID: 8c91e0ac-5e8d-41ca-8845-c6c72f27ad1d

@atulkc if you can't query about it ,i think you deploy chaincode isn't success.or you can 'docker ps ' get the chaincode containers .
atulkc
2016-09-29 17:42
@arvin chaincode was deployed successfully and I had invoked it successfully previously. Also, query operations are successful. Somehow now the invoke operations are not getting added in the blockchain and new changes won't propagate to world state.
atulkc
2016-09-29 17:45
also I noticed that (by doing `docker ps -a`) that new docker containers are not getting created

@sukrith `peer` should be in your path if you have gone through the devenv setup, and built the `peer` executable via the `make` command. you may have to relogin for the path changes to take affect

Hi, Just trying to clear my concept. In general Blockchain is an irrevocable and immutable ledger - Hyperledger Fabric also is - as per definition.
Now, I have been using a table to store my data in Fabric.
But If I have a replaceRow API or deleteRow API, then isn't that going to conflict the concept of Blockchain itself ?
ghaskins
2016-09-29 23:58
@ashishkel I think you are conflating the state of a chaincode application with the history of the state changes
ghaskins
2016-09-30 00:00
something like “deleteRow” can help transition from one state to the next, but that is independent of the history of steps that brought us to a specific state at a point in time
ghaskins
2016-09-30 00:00
the “blockchain” is part of the history mechanism
ghaskins
2016-09-30 00:00
does that make sense
ghaskins
2016-09-30 00:00
?
ghaskins
2016-09-30 00:01
so your application can “mutate” its state to transition from an old state to a new state, and the blockchain can record the history of all of those transitions, and both concepts can coexist
ashishkel
2016-09-30 00:16
@ghaskins , Hmm. Now I get it. History remains intact. Hence the concept of Blockchain prevails.
And any such operation like delete/replace etc, is actually transforming the present state -> to another state.
Ohkay. Agreed. Thanks @ghaskins
ghaskins
2016-09-30 00:19
Right. It's like how git works. You can delete a file "now", but the history that the file once existed still remains

2016-09-30 06:09
@nits7sid I haven't used BlueMix so I may not have the necessary context for your question. However, it seems like there have been a number of challenges because BlueMix is still on Fabric v0.5 while everything else has moved forward with backwards incompatible changes
nits7sid
2016-09-30 06:12
ohh. @ccooper21 Is it because of gRPC calls with tls?
nits7sid
2016-09-30 06:12
or the error is specific to bluemix blockchian network?
ccooper21
2016-09-30 06:18
not sure. I just know that the difference in versions causes somethings to break. e.g. example chaincode that works with BlueMix does not work with Fabric at the moment, and vica versa. I'm just speculating that your problem might be related, especially if you are using the most recent Node SDK code
ccooper21
2016-09-30 06:19
I think the Node SDK is new as of this month, so I'm guessing there isn't a v0.5 compatible version

@mart0nix membersrv should be enabled with "ACA" in order to work with attributes. Try using command "MEMBERSRVC_CA_ACA_ENABLED=true membersrvc" for starting membersrv it worked for me.

Hi Guys. What could cause the "Error:Failed to launch chaincode spec(Could not get deployment transaction for " error message. I'm deploying chaincode with the nodejs SDK, it is returning a chaincodeID so the I guess the deployment is succesfull right
garisingh
2016-09-30 08:55
@thefringe (nice name btw :wink: ) - the deploy transaction is async - so while you get back a response - it basically means the transaction was accepted / acknowledger by the peer
garisingh
2016-09-30 08:56
it does not mean the chaincode deployment was succesful

2016-09-30 08:56
you should see entries in your peer log if deployment fails

@thefringe - related to the chaincode issue above? the error is coming from membership services and if seeing that as result of the deploy transaction then likely an issue with the peer getting transaction certificates to submit the deploy transaction. Exactly how are you running your peer(s) and membership services?
thefringe
2016-09-30 10:23

garisingh
2016-09-30 12:00
@ccooper21 - we should probably clarify - the idea is to remove the transactional REST API out of the peer but (hopefully) within a reasonable timeframe provide an analogous interface which runs outside the peer (basically build a REST server which uses the SDK on its backend)
garisingh
2016-09-30 12:00
but alternative is the client SDKs - we have NodeJS today and will have others in the future. They all use the native GRPC APIs

Hi everyone. I'm attempting to install fabric and have docker installed on my machine. I am following option 2 as detailed in the docs here: http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/
However when i attempt to execute the 'docker pull hyperledger/fabric-peer:latest' command i get a 'docker: Cannot connect to the Docker daemon. Is the docker daemon running on this host?.' message. I've looked around but can't seem to solve it. So far i understand that I need to log out and then back in to the docker registry after adding my username to a docker group? Could anyone who has come across this issue help me solve it? Thanks :slightly_smiling_face:

Hello, I'm trying to init the chaincode https://github.com/hyperledger/fabric/blob/master/examples/chaincode/go/asset_management_with_roles/asset_management_with_roles.go
but for some reason assignerRole, err := stub.GetCallerMetadata() returns zero length []byte for assignerRole
I tried it locally in dev & regular mode and in Bluemix and it returns no metadata for in any case and for different users in "secureContext"
Actually, my current task is to get info about current user (name, role) to check his permissions in chaincode functions. Can you please advise?

so options:
1) try `sudo docker info` - if this is successful then the daemon is running and you simply need to run command as root or via `sudo`
2) if you get the same error, then `sudo service docker start`
3) if you want to run `docker` commands as a non-root user, then you'll need to add your userid to the `docker` group

hhadass
2016-09-30 15:16
@garisingh yes! thanks :smile: Can this be added to the docs possibly? or am i the only one with this problem?
garisingh
2016-09-30 15:18
the error is a bit odd since it looks like Docker was started with both tcp and unix socket (default) listeners
garisingh
2016-09-30 15:18
so `docker pull` should have worked
hhadass
2016-09-30 15:19
@garisingh ah i see
jzhang
2016-09-30 15:48
does anybody know what this error might mean?
error={"error":{"code":12,"metadata":{"_internal_repr":{}}},"msg":"Error: unknown service protos.Peer"
got this when chaincode deploy targeting a docker-based network from my host system (using peer address , the port 7053 is mapped to docker port 7053 in docker-compose)
jzhang
2016-09-30 15:55
(i’m switching to vagrant for now, but still curious what the above error means)
sukrith
2016-09-30 15:56
for testing purposes is there a way to delete everything stored in the worldstate in the init function of chaincode
hhadass
2016-09-30 16:19
@garisingh is there a way of removing the output of `ps -ef|grep docker` so i don't get the same issue again?
jzhang
2016-09-30 16:24
never mind my question above, should’ve used port 7051 instead of 7053 for deploying to peer

sorry @hhadass - was away for a bit. looks like you should `kill` the current running docker processes and then start docker via `sudo service docker start`

@sukrith I doubt it, you will probably have to turn your peer off and on again to wipe it.

Hi, I'm having some issues again getting fabric up and running. I've followed the docs here, http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/ using option 2 for setting up the chaincode and everything works fine. I'm now attempting to set up the network with validating peers following this guide http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Network-setup/#starting-up-validating-peers and when i run `docker images` i get a `Cannot connect to the Docker daemon. Is the docker daemon running on this host?` error. Any tips ?
yacovm
2016-10-02 07:23
can you do a `ps -ef | grep docker` and tell the output?
rafael
2016-10-02 07:57
Hi All,
rafael
2016-10-02 07:59
How can I start one peer node on a host and one peer node on another host?
yacovm
2016-10-02 08:24
you need one of them to be the root peer of the other
rafael
2016-10-02 08:50
@yacovm Could give me more details?
yacovm

yacovm
2016-10-02 08:52
yacovm
2016-10-02 08:53
I hope I'm not mis-informing you
rafael
2016-10-02 08:53
For example,
yacovm
2016-10-02 08:54
you need to have the `CORE_PEER_DISCOVERY_ROOTNODE` variable reflect one of the others
rafael
2016-10-02 08:54
Host 1 has IP 192.168.0.1 and its docker's IP is 172.17.0.2 (dockerIP1)
rafael
2016-10-02 08:55
Host 2 has Ip 192.168.0.2 and its docker 's IP is 172.17.0.3(dockerIP2)
yacovm
2016-10-02 08:55
why is the docker's ip different?
yacovm
2016-10-02 08:55
the docker assigns consecutive ip addresses
yacovm
2016-10-02 08:56
in any case- then you'll need maybe to ensure there is port forwarding between the two hosts to port 7051 and give the `CORE_PEER_DISCOVERY_ROOTNODE` to be the host's ip
rafael
2016-10-02 08:59
docker run --rm -it -e CORE_VM_ENDPOINT=http://192.168.0.1:2375 -e CORE_PEER_ID=vp1 -e CORE_PEER_ADDRESSAUTODETECT=true -e CORE_PEER_DISCOVERY_ROOTNODE=192.168.0.1:7051 hyperledger/fabric-peer peer node start
rafael
2016-10-02 08:59
Do you think it correct?
yacovm
2016-10-02 09:00
no
yacovm
2016-10-02 09:00
what's the point of having the discovery rootnode as your own?
yacovm
2016-10-02 09:00
it has to be a different host than you
rafael
2016-10-02 09:05
Could give me an example?
yacovm
2016-10-02 09:10
yeah I can try
yacovm
2016-10-02 09:12
host1: 192.168.0.1:
`docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_LOGGING_LEVEL=DEBUG -e CORE_PEER_ID=vp0 -e CORE_PEER_ADDRESSAUTODETECT=true hyperledger/fabric-peer peer node start`
host2: 192.168.0.2:
`docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_PEER_ID=vp1 -e CORE_PEER_ADDRESSAUTODETECT=true -e CORE_PEER_DISCOVERY_ROOTNODE=192.168.0.1:7051 hyperledger/fabric-peer peer node start`
But you need to have host1 to forward tcp packets on port 7051 to 172.17.0.2
rafael
2016-10-02 09:17
I got it. I'll try it.
rafael
2016-10-02 09:17
Thank you so much.
yacovm
2016-10-02 09:18
np, if it doesn't work tell me, although I need to go buy food before the stores close else I'll end up starving

replace the fd thing

that's ok I'm not a docker expert myself

Hello, Can anyone share a knowledge regarding the Go chaincode method stub.GetCallerMetadata(). Currenly it returns zero bytes of information in both IBM Bluemix and local peer. I tried running chaincode from different users. What should I do to get current caller info (user name or roles) from the method? Or is there any other way to get that during runtime?
aliblackwell
2016-10-03 09:28
Ah @hhadass I did wonder about that. Presumably docker for mac just sets docker up and running in the background. My suggestion would be to go through the basic docker setup instructions so any daemon is definitely running, and then try again?

2016-10-03 15:51
there is an example showing how to implement such a story

chaincode invokes chaincode

I guess you want something like that, hm?

yea
sukrith
2016-10-03 15:52
essentially i want to call Invoke(…)
sukrith
2016-10-03 15:52
from an existing function in the chaincode
hgabor
2016-10-03 15:53
see this: examples/chaincode/go/chaincode_example04/chaincode_example04.go

if it turns out that it is not what you want please write me :slightly_smiling_face:

i see so exampl04 invokes example02. What if i wanted example04 to invoke example04
hgabor
2016-10-03 15:57
I am not sure that it is possible for a chaincode to call itself recursively. or if it is, I won't be sure that it is a good thing. @muralisr ?
muralisr
2016-10-03 15:58
it is possible… we do maintain stack for chaincode invoks
muralisr
2016-10-03 15:59
but its not recommended obviouly
hgabor
2016-10-03 15:59
I think the same, that it is a no-no
muralisr
2016-10-03 15:59
agreed
sukrith
2016-10-03 15:59
i mean it depends on the application but okay il try to avoid it
muralisr
2016-10-03 16:00
key is this
muralisr
2016-10-03 16:00
as opposed to generic programming, there is the notion of the state key vars for the chaincode
muralisr
2016-10-03 16:01
as the chaincode clearly can access its own state, there is no need to implement it via recursion
muralisr
2016-10-03 16:01
it may be convenient but it is more expensive for obvious reasons

Could anyone help me on how to setup the CORE_PEER_ENDPOINT,CORE_PEER_DISCOVERY_ROOTNODE, and other related parameters? I have tried the configuration in the guide but all of that is the configuration for the peer running in the same docker with ip like 172.16.0.x. And after I deploy it in different VMs, it not working anymore.

Fabric-baseimage has been fixed and Ubuntu version has been updated from 14.04 to 16.04.
https://gerrit.hyperledger.org/r/#/c/1417/
We can use rocksdb package at Ubuntu 16.04 to reduce building time.
The setup script (scripts/common/setup.sh) still compiles rocksdb. Can I change this step to apt-get install command?
ghaskins
2016-10-04 16:55
@yuki.k I didn’t realize rocksdb was included in 16.04
ghaskins
2016-10-04 16:55
do you know what version they are building?
ghaskins
2016-10-04 16:55
i guess I can look in launchpad
ghaskins
2016-10-04 16:57
it looks like it might be 4.1, which is good, but its only built for x86, which is ba
ghaskins
2016-10-04 16:57
bad
ghaskins
2016-10-04 16:57
the question in my mind is: why are you concerned about the build time in general?
ghaskins
2016-10-04 16:58
no one should really need to build the baseimage other than people working on the baseimage, so I am wondering why you care?
yuki.k
2016-10-04 17:59
@ghaskins
Thank you for your commment.
I am building Fabric outside of Vagrant. So I care about building time.
If developers can avoid compiling rocksdb, it would be great!!
ghaskins
2016-10-04 18:08
i see
ghaskins
2016-10-04 18:09
i think the baseimage plumbing probably cannot adopt the ubuntu package until they solve the multi-arch problem
ghaskins
2016-10-04 18:09
but I see no problem in you consuming it
yacovm
2016-10-04 18:13
compiling rocksDB doesn't take much time...
ghaskins
2016-10-04 18:14
its about 5m in my experience, which can certainly be annoying
ghaskins
2016-10-04 18:14
but if someone is curating their own devenv, they also shouldnt need to do it very often
ghaskins
2016-10-04 18:15
@yuki.k curious why you do not use the devenv ?
vzhou
2016-10-04 18:19
@ghaskins i'm not yuki.k but in my case I needed to build from source on digital ocean droplets with 512MB memory; i tried running vagrant but it just died on me
ghaskins
2016-10-04 18:20
ah, that makes sense
ghaskins
2016-10-04 18:20
i think it tries to provision 4G ram

i dont actually need to build from source, but last week the peer and membersrvc images hadnt been updated for 2 weeks

vzhou
2016-10-04 18:21

yacovm
2016-10-04 18:24
digital ocean droplets are dockers or something special like cloud foundry or heroku? @vzhou
yuki.k
2016-10-04 18:45
@ghaskins My host machine is Linux OS(Ubuntu). I build fabric with vagrant but I use libvirt as a hypervisor software. So I can't use the devenv directly.
ghaskins
2016-10-04 18:47
I assume you mean you run vagrant with your own Vagrantfile?
yuki.k
2016-10-04 18:57
@ghaskins As you said, I use my own Vagrantfile.
ccooper21
2016-10-04 19:04
@ghaskins This sounds related to the work I did to get the devenv deployed at AWS instead of running it locally. Though, apparently there are two flavors. 1) Running the devenv locally with an alternate VM solution to Virtualbox, and 2) Running the devenv somewhere in the cloud
ccooper21
2016-10-04 19:05
I mention the devenv as a point of reference, but it seems like even if you wanted to do a production deployment you would need to follow the same steps

Hi everyone, If you are looking for help to navigate Jira and see what the current prioritized list is for fabric at least from my view, please see the #requirements channel. I ask if there is something in your mind that is out of priority order, or simply missing in the near term, please bring it up in the #requirements slack channel. I’m working to keep the list in order as best I can, but need your feedback as well to help rank these.

@wangbin767 I'm just guessing here, but if I wanted to setup a peer network with multiple computers or VMs I would run one peer per node/computer and potentially setup Nginx to reverse proxy traffic from the VMs network interface to the internal Docker interface.
wangbin767
2016-10-05 04:50
@ccooper21 thanks, I have tried only start one peer per VMs, it seems the peer can find each other, but it always report “duplicate” error in the log.
ccooper21
2016-10-05 04:50
are you giving each peer a unique name?
wangbin767
2016-10-05 05:44
yes，the detailed error message is Peer FSM failed while handling message (DISC_HELLO): current state: created, error: transition canceled with error: Error registering Handler: Duplicate Handler error: {name:"vp1" 172.17.0.3:7051 VALIDATOR }
wangbin767
2016-10-05 05:45
the name is different on each peer, but the ip address seems the same
wangbin767
2016-10-05 05:49
I have started two peer on two VMs and both of these peer’s ip is 172.17.0.2. I have tried to setup the CORE_PEER_ADDRESS,it can changed the ip of the peers but the same error still exist.
ccooper21
2016-10-05 08:17
@wangbin767 I guess that makes sense that if multiple peers have the same IP address it may cause confusion. The 172.17.0.0/12 network I believe is just an internal Docker nextwork within your host. There must be a way to change the network, but I don't know Docker well enough to know where that is controlled.
ccooper21
2016-10-05 08:20
Maybe the real answer is that in production mode there is no need/reason to run the peer inside a docker container (just the chaincode, which happens automatically). I'm also not sure how you set that up though.
wangbin767
2016-10-05 08:27
I think with the docker it make the deploy of the fabric more easy on different machine and VMs.
thomas.marckx
2016-10-05 08:29
What are the different json structures that can be returned by the fabric?
According to the `fabric.proto` a Block structure looks like this:
```message Block {
uint32 version = 1;
google.protobuf.Timestamp timestamp = 2;
repeated Transaction transactions = 3;
bytes stateHash = 4;
bytes previousBlockHash = 5;
bytes consensusMetadata = 6;
NonHashData nonHashData = 7;
}```
But when I request the block number 1 it looks like this:
```
{
"previousBlockHash": "RrndKwuojRMjOz/rdD7rJD/NUupiuBuCtQwnZG7Vdi/XXcTd2MDyAMsFAZ1ntZL2/IIcSUeatIZAKS6ss7fEvg=="
"nonHashData": {
"localLedgerCommitTimestamp": {
"seconds": 1475655114
"nanos": 576500533
}
"chaincodeEvents": [1]
0: {}
}
}
```
There’s no transactions clause … not even an empty one.
Can this be expected? and why don’t have all the blocks the same structure?

2016-10-05 08:31
there are several things that you'll need to do if you want to allow Docker containers on different machines to communicate. I won't get into overlay networking because it is probably overkill for what you want to do here. Assuming you are running one peer per machine/VM, you should start the peer container on each host with the `--net=host` option . You'll then want to configure the `CORE_PEER_DISCOVERY_ROOTNODE` to be the host ip address of at least one of the machine (host ip meaning not the docker bridge address but rather than IP that other machines can connect to you with)
garisingh
2016-10-05 08:33
for safety sake, you can also configure the `CORE_PEER_LISTEN_ADDRESS` and/or `CORE_PEER_ADDRESS` to be [machine ip]:7051 as well
garisingh
2016-10-05 08:34
do this on each machine
ccooper21
2016-10-05 08:41
I was just looking at the following. It may be helpful in getting the `--net=host` option working.
wangbin767
2016-10-05 08:45
thanks @garisingh and @ccooper21 ! I will take a try on this solution.

@wangbin767 I ran into the same problem a few days ago and was given the suggestion to rebuild my environment. Apparently there was some problem with the snapshot of the code I was using. All was better after refreshing the code. As a workaround though, I think you can locally create a "latest" Docker tag for the "fabric-baseimage" container
ccooper21
2016-10-06 04:18
I pulled the code that had a problem about 2 weeks ago from today, and I pulled the working code about a week ago from today if that helps.
ccooper21
2016-10-06 04:20
@niubwang I'm still learning my way around Docker so this is kind of a guess, but I would try connecting to one of the containers hosting the "peer" and look at the interfaces/routes that are available (e.g. use "ifconfig"). If your containers are only communicating on the 172.17.0.0/12 network then it makes sense they can't see the host address.
ibmamnt
2016-10-06 04:41
I have not checked this thread for a long time, sorry if I missed the announcement. Quick question, Is "update of chaincode" to existing Docker image or create the image with the same name supported now ?
ccooper21
2016-10-06 07:12
@ibmamnt I'm not sure I'm fully understanding your question, but I believe a new Docker images is built each time you deploy chaincode. Since chaincode (and hence the corresponding image) is identified by a hash code (at least in production mode) there is no updating of previously built images
ibmamnt
2016-10-06 07:15
Right, that what I thought. Suppose I frequently change the chaincode, say 3 times / per day, and service team needs the feature right away on the same day, I need to deploy 3 chaincode / day
ibmamnt
2016-10-06 07:16
And project last for 100 days. And there are 4 peers.
ibmamnt
2016-10-06 07:16
This means we need to have 3*100*4 = 1200 Docker images.
ibmamnt
2016-10-06 07:18
On docker images have 1Gbyte, so probably we need 1.2T byte disk. This is what I think the problem.
ibmamnt
2016-10-06 07:18
In stead of having 1200 images, I just want to have 4 latest image only.
ibmamnt
2016-10-06 07:19
Note that I have no access to VMs which host peers.
garisingh
2016-10-06 07:28
@ibmamnt - chaincode lifecycle support will not be coming until v1.0 (by this I mean the ability to "upgrade" existing chaincode)
ibmamnt
2016-10-06 07:31
Oh, I understood. That is sad news... I'll over come somehow.
garisingh
2016-10-06 07:36
Agree - it is sad news, but as it requires some fairly deep changes, we opted to push to the next major release. Not that this is supported, but you could probably deal with this via interactions with the Docker endpoints on each host running chaincode - meaning you could build updated chaincode images outside of the fabric, leverage the same image name, push that to a private Docker registry, then pull from that registry on each host running chaincode, kill the existing containers and then when fabric recreates the container (since it would be gone) in theory you would be running the updated chaincode
garisingh
2016-10-06 07:36
but that of course means you need to control / have access to all nodes running the peers / chaincode
ccooper21
2016-10-06 07:49
@garisingh When you say chaincode lifeycle management will be coming in v1.0, is there documentation anywhere describing thoughts on how this might be achieved? Or is it just on a punch list of things that need to get done?
garisingh
2016-10-06 08:02

Recently I’ve switched to MacOS Sierra and starting to get this warning while building my code ```# http://github.com/hyperledger/fabric/vendor/github.com/mattn/go-sqlite3
In file included from ../../vendor/github.com/mattn/go-sqlite3/sqlite3-binding.c:2:

Has anyone seen it? Is there known solution for that?
c0rwin
2016-10-06 15:22
Additionally I’m getting this error, which I’m not sure how to solve: ```# http://github.com/hyperledger/fabric/vendor/github.com/tecbot/gorocksdb

@c0rwin havent tried sierra yet, but I do know the build in general
ghaskins
2016-10-06 15:24
first question: are you building in vagrant devenv, or somewhere else (like native on sierra)
yacovm
2016-10-06 15:24
he's building on native
ghaskins
2016-10-06 15:24
ok…I cant speak to the sqlite issue, but the rocksdb issue sounds like you either dont have rocksdb installed, or you dont have CGO envvars set properly
mart0nix
2016-10-06 15:25

mart0nix

this works for me

ghaskins
2016-10-06 15:25
ty @mart0nix, that looks good
ghaskins
2016-10-06 15:25
@c0rwin that rocksdb/c.h thing usually comes up when your envvars arent set right
ghaskins
2016-10-06 15:26
so I would start there, @mart0nix provides a good base set
ghaskins
2016-10-06 15:26
of course, YMMV on the actual paths

@ghaskins, @mart0nix thanks, I’ve changed flags or env on my laptop, while I guess upgrade might have messed something
c0rwin
2016-10-06 15:27
I will take a look on your suggestions and check them later
ghaskins
2016-10-06 15:27
yeah, you might need to brew-update, or whatever you are using to install rocksdb
ghaskins
2016-10-06 15:28
if you cant sort it out, just post back
c0rwin
2016-10-06 15:28
@ghaskins that was the first thing I did
ghaskins
2016-10-06 15:28
and let us know about the sqlite thing if it persists
c0rwin
2016-10-06 15:28
apparently w/ no success though
ghaskins
2016-10-06 15:28
ultimately it seems like your -L flag isnt right, so start there
c0rwin
2016-10-06 15:28
sure, I need to go, but will give it a try latter
ghaskins
2016-10-06 15:29
sorry, your -I

I have a question about data modeling
mart0nix
2016-10-06 15:32
my current application would require something like 5-6 SQL tables if built on a regular web stack

Hum ... private IP on IBM Bluemix Containers is different : Private IP: 172.32.0.15

2016-10-06 15:33
so I'm wondering if I should use native GO structs with embedded lists or use shim.Tables with PKs and FKs and do pseudo SQL Joins in code ?
mart0nix
2016-10-06 15:33
any suggestions in terms of what would be easier for READ/WRITE ?
mart0nix
2016-10-06 15:33

I have a question, i run the fabric-peer using docker toolbox in win7, but i can't deploy the chaincode, the error is :

yacovm

we really need a FAQ section somewhere with common problems and their solutions :sweat:
yacovm
2016-10-06 15:44
niubwang, you docker needs to be set up according to the dev env, are you using the vagrant image?
niubwang
2016-10-06 15:44
i am not using the vagrant
yacovm
2016-10-06 15:45
change the file accordingly: `/etc/init/docker.conf: DOCKER_OPTS="-H -H unix:///var/run/docker.sock"`
yacovm
2016-10-06 15:45
and then restart docker
mart0nix
2016-10-06 15:46
@yacovm yeah documentation is practically non-existing : ))
niubwang
2016-10-06 15:46
"/etc/init/docker.conf" on windows?
yacovm
2016-10-06 15:46
... you're using docker on windows?
niubwang
2016-10-06 15:46
yes..
yacovm
2016-10-06 15:47
oh then you need the docker to listen to that port
mart0nix
2016-10-06 15:47
how about that

I've no idea what to do and how to do that on windows, I consider docker + windows something inherently unholy :slightly_smiling_face:
niubwang

thanks yacovm, but i really can't find the way to set the docker_opts on windows
niubwang
2016-10-06 15:52
anyone can help me ? does the fabric-peer can deploy chaincode using docker toolbox on widows 7?
yacovm
2016-10-06 15:53
Why not simply use the vagrant image?
yacovm
2016-10-06 15:53
Just curious
niubwang
2016-10-06 15:57
i think it is complex to use the vagrant
niubwang
2016-10-06 16:05
@tuand hi, do you know the fabric-peer can deploy chaincode using docker toolbox on windows7? not the vagrant
niubwang
2016-10-06 16:05
\
niubwang
2016-10-06 16:06
when i do this, it can't create the chaincode container
ghaskins
2016-10-06 16:53
@niubwang can you provide more details on "i think it is complex to use the vagrant"
ghaskins
2016-10-06 16:53
in my mind, it is precisely the opposite
ghaskins
2016-10-06 16:53
cd devenv && vagrant up
ghaskins
2016-10-06 16:53
done
ghaskins
2016-10-06 16:54
the challenge is typically when someone has limitations for VMX/vbox, but i’ve never heard that it was too complex

To be clear: this is running against a private build with ubuntu updated to 16.04, not something we have committed
ghaskins
2016-10-06 17:33
but I am at a loss…the docker images themselves seem ok
ghaskins
2016-10-06 17:33
e.g. I can manually launch membersrvc and peer via “docker run” incantations
ghaskins
2016-10-06 17:33
but when its composed, it seems that the peer cannot see the CA
ghaskins

@mrshah commented on @ghaskins’s file https://hyperledgerproject.slack.com/files/ghaskins/F2L81MJP5/-.txt: @ghaskins I saw exactly the same thing.. worked for me after a machine reboot
ghaskins
2016-10-06 18:15
@mrshah ty for the info, but this was a clean install
ghaskins
2016-10-06 18:16
and its consistent….it seems there is something in the 16.04 setup that is breaking this
ghaskins
2016-10-06 18:18
this is really bizarre…i think its the wait-for script that is broken
ghaskins
2016-10-06 18:19
maybe there is a utility it is using that isnt installed
garisingh
2016-10-06 18:19
@ghaskins - is this both Vagrant and the Docker images using Ubuntu 16.04
ghaskins
2016-10-06 18:19
@garisingh yeah, full rebuild of both with my prerelease v0.2.0 baseimage
ghaskins
2016-10-06 18:19
i bet the wait for script is calling something that isnt installed on 16.04 by default
ghaskins
2016-10-06 18:19
because I can netcat the CA while the compose runs and they are talking to each other
ghaskins
2016-10-06 18:22
i think its netcat
mrshah
2016-10-06 18:25
@ghaskins I spent a lot of time today trying to figure this out. Initially everything started fine, suddenly I ended up in this issue and it would never start. Spent a lot of time investigating -> finally a reboot and it worked.
I will stay tuned if you find something, while I try to look into it too
ghaskins
2016-10-06 18:26
@mrshah ok, but I think its likely unrelated
ghaskins
2016-10-06 18:26
im upgrading the core platform, i think thats what broke it in my case
mrshah
2016-10-06 18:27
no problem
ghaskins
2016-10-06 18:32
@mrshah that said, if you are seeing flakiness, we want to know about it
ghaskins
2016-10-06 18:32
so let us know if that pops up again
mrshah
2016-10-06 18:32
sure, will do
mrshah
2016-10-06 18:38
I was trying it on `Ubuntu 16.04.1 LTS` and I saw exactly the same issue where peers couldn't reach the membersrvc. So I added a debug container in docker-compose by running bash and linking it to membersrvc. I couldn't telnet or nc -z to membersrvc on port 7054 from the debug container.
I will let you know if it happens again and other debug info that I find
muralisr
2016-10-06 19:23
@ghaskins @mrshah don’t want to mislead but this error could be relevant and something you are running into here ? https://jenkins.hyperledger.org/job/fabric-verify-x86_64/1652/console
ghaskins
2016-10-06 20:20
@mrshah ah, out of curiosity, did you mean up updated the images like fabric-membersrvc to use 16.04?
ghaskins
2016-10-06 20:20
or just that you were executing on 16.04?
mrshah
2016-10-06 20:25
@ghaskins I was just executing on 16.04 and pulled the images on hyperledger/fabric
ghaskins
2016-10-06 20:27
i see, I dont suspect it was the same problem
ghaskins
2016-10-06 20:27
this particular problem I was chasing was specific to 16.04 within the fabric images

@abhisingh - I was having similar issues - try this one -> https://github.com/ratnakar-asara/hello-blockchain
lenh
2016-10-07 11:06
it seems the node sdk fakes certain issues when things go wrong and then it "looks" like the deploy worked when in fact it did not...
lenh
2016-10-07 11:07
pull that repo and you'll see that there is a `src/chaincode` dir in which the chaincode MUST reside and also the `vendor/...` dir structure which is needed
lenh
2016-10-07 11:08
I had endless problems with example02 until @ratnakar provided me with the above which then worked like a charm and actually finally got me going.... so credit where due!

mart0nix
2016-10-08 13:20
guys - there's no datetime column field in the Table interface right ?
muralisr
2016-10-08 13:20
you mean as a column type ?
muralisr
2016-10-08 13:21
if so no
mart0nix
2016-10-08 13:23
yeah
mart0nix
2016-10-08 13:24
@muralisr I saw there were plans for SQL-like query support in the future
mart0nix
2016-10-08 13:24
so I'm wondering if this Table interface will become something like a SQL table with foreign keys to other tables and full support for other column types?
muralisr
2016-10-08 13:25
let me refer to @dave.enyeart
dave.enyeart
2016-10-08 13:29
The focus for now is on JSON support, to support complex objects without the more painful relational/table mapping. There are good options out there for sql-like query across JSON documents. That said, we’d like to make the data architecture pluggable so that a table metaphor could be plugged in backed by relational tables. Let me ask this - is there a specific reason you want to use a table metaphor instead of a json document metaphor?
mart0nix
2016-10-08 13:31
well a json metaphor will be ideal
mart0nix
2016-10-08 13:31
my application requires JSON(or XML) documents coming in
mart0nix
2016-10-08 13:32
I want to parse those and store them somehow in the chain so that I can query fields later
mart0nix
2016-10-08 13:32
my case is that I don't have to EDIT or DELETE old records - just add new ones and be able to query
mart0nix
2016-10-08 13:32
@dave.enyeart does that make sense ?
dave.enyeart
2016-10-08 13:34
very much makes sense. so the work that is beginning now will help you a lot - chaincode persisting json documents backed by a data store that supports json query. i am working on a proposal this weekend and will post an updated presentation, watch the fabric-ledger-dev channel for updates
mart0nix
2016-10-08 13:35
oh that would be awesome
mart0nix
2016-10-08 13:36
@dave.enyeart are you guys creating a new engine or trying to accommodate an existing DB ?
dave.enyeart
2016-10-08 13:36
excellent, will look forward to getting your detailed feedback after i post
dave.enyeart
2016-10-08 13:36
it will be pluggable, looking at couchdb as an initial data store
wangbin767
2016-10-08 13:36
@ghaskins is that means I can’t use any image pulled from docker hub?
garisingh
2016-10-08 13:40
@wangbin767 - you need to build the `fabric-ccenv` image from src but you can use all the other images from Dockerhub
garisingh
2016-10-08 13:41
you can also likely just do `docker tag hyperledger/fabric-peer:latest hyperledger/fabric-ccenv:latest` as well if working with Golang chaincode
ghaskins
2016-10-08 14:09
@wangbin767: as @garisingh said: it's not that the images there aren't usable, they just aren't complete
ghaskins
2016-10-08 14:09
I concur with @garisingh s workaround
ghaskins
2016-10-08 14:12
We are working on making a complete set available in one of the upcoming releases
wangbin767

sorry, should be this one https://hyperledger-fabric.readthedocs.io/en/latest/Setup/Network-setup/
wangbin767
2016-10-08 14:22
you have to tag the fabric-baseimage and only after that the chaincode can run correctly.
wangbin767
2016-10-08 14:24
I think somebody should amend this instruction ,add “docker tag hyperledger/base-image:latest hyperledger/fabric-peer:latest” after “docker pull hyperledger/fabric-membersrvc:latest"

@abhisingh commented on @abhisingh’s file https://hyperledgerproject.slack.com/files/abhisingh/F2LMD9KGW/-.sh: Hi @ghaskins and @garisingh, Please help me to solve this problem I am facing while deploying chaincode.
garisingh
2016-10-08 17:00
@abhisingh - are you running the peer using docker-compose? can you share your compose file? if not running in Docker, can you share your core.yaml or start command used for the peer?
garisingh
2016-10-08 17:01
looks like you somehow have the wrong value for `CORE_VM_ENDPOINT`
arvin
2016-10-09 08:35
how can i rolling up chaincode?
garisingh
2016-10-09 09:07
??? - not sure I understand the question
arvin
2016-10-09 09:13
chaincode upgrade ,transactions don't be affect
arvin
2016-10-09 09:15
or chaincode upgrade ,tsn date will be retain on host
garisingh
2016-10-09 10:42
chaincode upgrade is planned for the v1.0 release but is currently not supported
wangbin767
2016-10-09 21:02
I always got this error when I query the chaincode, is there anyone know why?
wangbin767
2016-10-09 21:02
Error: Error querying chaincode: rpc error: code = 2 desc = Error:Failed to execute transaction or query(Timeout expired while executing transaction)
wangbin767
2016-10-09 21:03
But actually I can invoke the chaincode , and it returns success
muralisr
2016-10-09 21:39
@wangbin767 invokes are asynchronous. Invoke is submitted for processing and returns to user
muralisr
2016-10-09 21:41
peer logs will specify if they succeeded or not. Query timeout suggests the chaincode might have exited with error…look at chaincode logs (and peer logs) to debug
arvin

@garisingh This is what I was facing
abhisingh
2016-10-10 10:44
"it is possible that you ran `docker-compose up`, then stopped the containers, slightly modified the yaml (perhaps changing the peer config) and then ran `docker-compose up` again?" - This was you comment.
abhisingh
2016-10-10 10:44
Actually I did the same but didn't modified the yaml file.
garisingh
2016-10-10 11:01
the only reason I can think that this would happen is that somehow something had already connected to your membersrvc container using the same ID. I've started / stopped peer and membersrv a few times using compose and the only time I got an error like that was when something (e.g. changing the YAML) forced creation of a new peer and/or membersrvc container
abhisingh
2016-10-10 11:08
Ok. Thanks :slightly_smiling_face: Let me explore this.
donovanhide
2016-10-10 20:30
Can someone give me a definition of the purpose of `CORE_VM_ENDPOINT`? I understand it is meant to point to a Docker port, but in a distributed system, should it not be unique for each peer so that they can start a chaincode instance locally? All the examples use the same address for each peer, which is confusing :slightly_smiling_face:
donovanhide
2016-10-10 20:37
Maybe I’m a bit confused by this reference to `CORE_VM_ENDPOINT`:
https://github.com/OpenBlockMesh/OBM-Fabric-GKE#core_vm_endpoint-setup
where there seems to be only one Docker container running the chaincode!
donovanhide
2016-10-10 20:40
Or is it multiple containers running on a single Docker instance? Confused :slightly_smiling_face:
cbf
2016-10-10 21:12
@donovanhide yes - @garisingh has been playing with a new approach using Docker in Docker where you would have a DinD container paired with a peer(s)
cbf
2016-10-10 21:13
but basically this is intended to provide the endpoint to a docker daemon that can spin up containers for the various chaincodes that are associated with a peer
donovanhide
2016-10-10 22:15
@cbf @garisingh I was going to suggest Docker in Docker :slightly_smiling_face: Glad the intention is to have a chaincode host per peer, that makes much more sense to me :slightly_smiling_face:
garisingh
2016-10-10 22:16
yep - it's just that for now, most people run all the peers on a single host just to test / simulate PBFT. And you'll notice that you could actually have the same CORE_VM_ENDPOINT on multiple hosts - it's basically binding the docker daemon to the Docker bridge address
garisingh
2016-10-10 22:17
but I've been messing with a compose config which use DinD to simplify the setup for folks.
donovanhide
2016-10-10 22:20
I’ve just been playing with getting a test rig set up on Kubernetes and was trying to work out all the yaml files and it did seem odd that all the examples were speaking to the same Docker instance. I want to test PBFT over multiple clusters, so I’d probably want at least one CORE_VM_ENDPOINT per cluster, but you soon realise that the configs can get quite out of hand and you need to stage the deployment over two or three phases. Having Docker in Docker would at least reduce that phasing by one step.

how can i change a block store more than one transactions?
madhavi
2016-10-11 11:29
while deploying chaincode , i am getting sending init failed
madhavi
2016-10-11 11:29
[chaincode] Launch -> ERRO 01a sending init failed(handler not found for chaincode cctest)
madhavi
2016-10-11 11:29
How to resolve it?
garisingh
2016-10-11 12:04
@madhavi - are you running in chaincode dev mode?
madhavi
2016-10-11 12:04
yes
garisingh
2016-10-11 12:05
then you'll need to compile and run your chaincode locally before running the deploy transaction
garisingh
2016-10-11 12:06
from the docs:
```
Starting and registering the chaincode
Run the following chaincode command to start and register the chaincode with the validating peer:
CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=0.0.0.0:7051 ./chaincode_example02
The chaincode console will display the message “Received REGISTERED, ready for invocations”, which indicates that the chaincode is ready to receive requests. Follow the steps below to send a chaincode deploy, invoke or query transaction. If the “Received REGISTERED” message is not displayed, then an error has occurred during the deployment; revisit the previous steps to resolve the issue.
```
madhavi
2016-10-11 12:06
yes i did that
garisingh
2016-10-11 12:06
(as an example)
madhavi
2016-10-11 12:07
i started two peers and i deployed by using one peer and in the other peer it is giving error as sending init failed
garisingh
2016-10-11 12:07
ah - so you'll need to start another instance of the chaincode and point it at the other peer as well
madhavi
2016-10-11 12:08
start another instance is enough or need to deploy with that peer also?
vigneswaran.r
2016-10-11 12:09
starting should be enough. deploy will propagate to other peers, I suppose.
garisingh
2016-10-11 12:11
you just need to start it. deploy transaction will go to both peers
madhavi
2016-10-11 12:12
ya its working thanq:)
madhavi
2016-10-11 12:14
if it is in public mode then also we have to create multi instances of chaincode? or how it will work?
muralisr
2016-10-11 12:21
@madhavi its only in `—peer-chaincodedev` mode the user is responsible for starting and attaching chaincodes to peer. Otherwise the peer manages that for the user… also `i started two peers..` - are you running the two peers in docker container ?
madhavi
2016-10-11 12:21
yes
muralisr
2016-10-11 12:22
ok
madhavi
2016-10-11 12:23
@muralisr if we remove --peer-chaincodedev then it run as a public mode right?
vigneswaran.r
2016-10-11 12:24
@madhavi we can say "production mode"
muralisr
2016-10-11 12:25
@vigneswaran.r its perfectly ok to run without that flag and let the peer manage chaincodes even when “developing"
muralisr
2016-10-11 12:25
its main use is to be able to debug chaincode problems with quick turnaround
vigneswaran.r
2016-10-11 12:26
@muralisr Got the point.
madhavi
2016-10-11 12:27
@vigneswaran.r ya in dev mode i start two peers and i start two instances of chaincodes for each peer its working
madhavi
2016-10-11 12:28
in production mode, we need to create multi instances for chaincode? or exact it works? how multi peers can access the same chaincode which is deployed by one peer?
muralisr
2016-10-11 12:29
@madhavi it might be a good idea to do a write up of that process (people typically run only one peer `—peer-chaincodedev` mode)
muralisr
2016-10-11 12:29
the deploy transaction is sent to all peers who deploy the same chaincode
muralisr
2016-10-11 12:31
so even in your current dev mode, if you send an invoke to a peer, you should see it run on both
madhavi
2016-10-11 12:31
ok
vigneswaran.r
2016-10-11 12:35
@madhavi Regarding production mode, the following is my understanding,
When you submit a deploy transaction by specifying the path of a chaincode through REST APIs, the peer reads the chaincode, compiles and creates a docker image containing the executable plus the necessary libraries, and starts the container. The same process is done by all the peers.
vigneswaran.r
2016-10-11 12:36
This is the case with CLI method too.
vigneswaran.r
2016-10-11 12:37
So, the point here is that the peer should have access to the chaincode (In case, you're trying with your custom chaincode, it should be inside the docker image where the peer started).
vigneswaran.r
2016-10-11 12:38
If you are using gRPC method (eg., app.go in asset_management example), the chaincode is read in the client side and sent to peer as payload, and the receiving peer sends to other peers and the same process of compilation, docker creation follows.
vigneswaran.r
2016-10-11 12:38
(Please feel free to correct, if I am wrong)
ghaskins
2016-10-11 12:39
@vigneswaran.r you are close
ghaskins
2016-10-11 12:40
the only nuance here is that the peer that receives the deploy (from the REST/CLI) packages the chaincode up as a payload before dissemination, same process as the GRPC/SDK
madhavi
2016-10-11 12:40
@vigneswaran.r k thanq i will try it
vigneswaran.r
2016-10-11 12:41
@ghaskins Thank you for the clarification...
ghaskins
2016-10-11 12:41
IOW, the normal peer fabric always receives a payload
ghaskins
2016-10-11 12:42
as an aside, note that when used in this manner, the receiving peer should be considered part of your client stack, not the general peer network
ghaskins
2016-10-11 12:42
that is why it would be expected to have access to your code to do the packaging, similar to how the SDK would
ghaskins
2016-10-11 12:43
typically this would be a locally deployed NVP
vigneswaran.r

A quick reminder: the ports have changed when moving from fabric v0.5 to v0.6. Be sure to take the correct actions when communicating with your fabric peers. The port mapping is: ``` v0.5 | v0.6
-------------
5000 | 7050
30303 | 7051
50051 | 7054
31315 | 7053

2016-10-13 16:34
@ghaskins, thanks for helping. Sorry if I bother you, but I'm still new to golang as well. I guess that the docker container is launched at line 107. I just can't see where I can find where docker.Client.CreateContainer() comes from. I see that whenever a new chaincode is deployed there's sibling docker containers appear. But I can't how the node's docker containers communicate with the host's docker deamon to do this...
sergefdrv
2016-10-13 16:39
@ghaskins probably, that's what I'm looking for: https://github.com/fsouza/go-dockerclient/blob/master/container.go#L549
ghaskins
2016-10-13 16:42
It's via the DOCKER_OPTS environment I believe
ghaskins
2016-10-13 16:42
It points the environment to an external daemon
sergefdrv
2016-10-13 16:45
Through docker inspect I just can't see that host's /var/run/docker.sock is mapped to the node container. I don't know any other way to communicate with the host's docker deamon

there is a setting in core.yaml (vm.endpoint) which specifies the Docker endpoint. If you are running in Vagrant, the docker daemon is also listening on tcp port 2375 as well as on the unix socket

FYI: If you have a fabric with chaincode that you suspect might be non-deterministic (or you want to run a long term test to exercise it and prove that it is not) I've whipped up a simple monitor as a node-red flow. Not a hardened app by any stretch, but it does the job and outputs a message showing the state of the hashes -- could be hooked up to any of the node-red social output nodes to get an alert on your phone etc ...

@kletkeman Might be good to draw up some coding best practices. Something like:
* Don’t range over maps.
* Don’t use unseeded sources of entropy
* Don’t use time.Time

you should really just use the Docker images with Docker for Mac.

previous declaration at vendor/github.com/Sirupsen/logrus/terminal_bsd.go:7
```
^^^ for this one the logrus package in vendor is broken for compiling on OSX. Basically you need to edit `vendor/github.com/Sirupsen/logrus/terminal_bsd.go` and delete `darwin`
The second error means you have the wrong version of RocksDB. Needs to be RocksDB 4.1. If you used brew to install it, it will be the wrong version

Is there a way to generate a random private key per node when testing PBFT consensus:
https://github.com/hyperledger/fabric/blob/master/peer/core.yaml#L83
Or is that the default behaviour if a privateKey is not specified?
garisingh
2016-10-14 17:49
@donovanhide - not sure why that is still around. with security enabled, each peer gets it own enrollment key from membership services
donovanhide
2016-10-14 17:50
@garisingh Thanks, guess that means I need to sort out my membershipsvc kubernetes config out first :slightly_smiling_face:
donovanhide
2016-10-14 17:51
Also, do the peer ids need to be unique?
https://github.com/hyperledger/fabric/blob/master/peer/core.yaml#L80
donovanhide

Basically trying to work out what needs to be supplied by kubernetes config maps to each member of a petset.

peer.id needs to be unique and for PBFT you should use vp0,vp1,...,vpX
donovanhide
2016-10-14 17:55
Setting your own peer id seems a little odd to me, as there could be accidental or malicious collisions. Ripple identifies nodes by generating an id from a hash of the public key of the private key, bitcoin account style.

and any suggestions on cryptographic / unique identities are most welcome
donovanhide
2016-10-14 19:10
Well here’s the ripple way:
https://github.com/rubblelabs/ripple/blob/master/crypto/ed25519.go#L20-L23
https://github.com/rubblelabs/ripple/blob/master/crypto/util.go#L35-L41
In words, the id is the ripemd160 hash of a sha256 hash of the public key, which is of course generated from the private key. For fabric, I guess this means deferring the creation of a peer id until the peer has enrolled with the membership services.
yacovm
2016-10-14 19:11
It's not that simple, you also need to prevent replay attacks
yacovm
2016-10-14 19:11
In fabric, at least
donovanhide
2016-10-14 19:12
Replaying which message?
yacovm
2016-10-14 19:12
Otherwise a cert-based key isn't sufficient IMO
yacovm
2016-10-14 19:12
Authentication between peers
yacovm
2016-10-14 19:12
I've been working on such a thing and its in my pipeline
yacovm
2016-10-14 19:13
But no ETA yet
donovanhide
2016-10-14 19:15
Not sure I understand the replay attack. You mean intercepting the message where the membership services supplies the enrollment key? If that happens, it’s game over for everything?
yacovm
2016-10-14 19:15
I don'tknow how ripple works but obviously getting a message from a peer that proves that the messge originated from the real peer doesn't prove the peer that sent the message is the real peer
donovanhide
2016-10-14 19:16
I guess the requesting peer has to challenge the membership services to sign something it randomly generated.
yacovm
2016-10-14 19:17
Yep
yacovm
2016-10-14 19:17
Exactly
yacovm
2016-10-14 19:17
No, wait
yacovm
2016-10-14 19:17
Not the membership
yacovm
2016-10-14 19:18
The peer that is servicing the connection needs to challenge the peer connecting to it
donovanhide
2016-10-14 19:19
>>with security enabled, each peer gets it own enrollment key from membership services
I’m talking about this step, are you as well?
yacovm
2016-10-14 19:20
"Setting your own peer id seems a little odd to me, as there could be accidental or malicious collisions. Ripple identifies nodes by generating an id from a hash of the public key of the private key, bitcoin account style."
yacovm
2016-10-14 19:20
I'm just saying that identifying nodes is also not trivial, because you need to corallate the connection with the peer
yacovm
2016-10-14 19:21
A node that says hey i'm totally the real node i swear here is my id isn't sufficient on a true byzantine environment
donovanhide
2016-10-14 19:22
Yep, if you used openssl you can use the PeerFinishedMessage as the challenge that both peers must sign.
donovanhide
2016-10-14 19:23
Here’s some ancient code that did that using Go openssl bindings:
https://github.com/rubblelabs/ripple/blob/912432194acc0afca7027228b0f8bdd177c3484c/peers/conn.go#L137-L149
yacovm
2016-10-14 19:23
Hmmm
donovanhide
2016-10-14 19:23
Arguably that was susceptible to the Triple Handshake Attack though.
yacovm
2016-10-14 19:23
Wait
yacovm
2016-10-14 19:24
But we use gRPC
yacovm
2016-10-14 19:24
How can we use this?
donovanhide
2016-10-14 19:24
Is grpc not talking over tls?
yacovm
2016-10-14 19:24
We don't have access to these layers AFIK
yacovm
2016-10-14 19:25
At the connection servicing side, at least i never saw how from the API you can derive that
donovanhide
2016-10-14 19:25
The TLSUnique field might be of interest:
https://golang.org/pkg/crypto/tls/#ConnectionState
donovanhide
2016-10-14 19:25
I’m no crypotgrapher though, you might want to consult an expert :slightly_smiling_face:
yacovm
2016-10-14 19:26
But we don't have a reference to these structs from the gRPC stream from what i know :disappointed:
donovanhide
2016-10-14 19:26
The theory is that you keep track of every message that went between the two TLS counterparties in the handshake and this is guaranteed to be the same on both ends.
donovanhide
2016-10-14 19:27
You can use that as the challenge that needs to be signed.
donovanhide
2016-10-14 19:27
yacovm
2016-10-14 19:29
I don't see how this helps
donovanhide
2016-10-14 19:31
You need a challenge that both peers can sign. Both peers speak over GRPC. If this GRPC communication is over TLS, when the TLS connection is established, you have a hash of all the messages involved (tls-unique). The first GRPC message between peers is another handshake that contains a signature of that hash along with the peer’s public key.
yacovm
2016-10-14 19:31
I don't have access to that hash however
yacovm
2016-10-14 19:32
From the API in the server side
donovanhide
2016-10-14 19:32
Where’s the code that does the peer grpc.Dial?
yacovm
2016-10-14 19:33
I need access in the server side method of the gRPC call
yacovm
2016-10-14 19:34
The dial is in the client side, i need the server to know the client is who it claims it is
donovanhide
2016-10-14 19:35
https://golang.org/pkg/crypto/tls/#Conn.ConnectionState
ConnectionState hangs off a net.Conn, which you’ll have access to on both sides.
donovanhide
2016-10-14 19:36
Where’s the code you are referring to?
yacovm
2016-10-14 19:37

2016-10-14 19:38
Sorry i'm typing in the phone app :expressionless: , no way to reference the line exactly
donovanhide
2016-10-14 19:38
Basically, this is what ripple does: every peer has a self-signed certificate, they establish TLS connections with each other, and then sign the peer finished message (openssl equivalent of tls-unique) using their application level private key.
yacovm
2016-10-14 19:39
Go to "// Chat implementation of the the Chat bidi "
yacovm
2016-10-14 19:40
Frm that object in the arguments i don't see a way of extracting the ssl information
donovanhide
2016-10-14 19:40
donovanhide
2016-10-14 19:41
I’m sure you get access to the tls.Conn around here.
yacovm
2016-10-14 19:41
That's the client side though
yacovm
2016-10-14 19:41
I need to access that on the server side
donovanhide
2016-10-14 19:42
Where’s the listen code?
yacovm
2016-10-14 19:43
Not easy to find with a phone...
donovanhide
2016-10-14 19:43
yacovm
2016-10-14 19:43
Yep
yacovm
2016-10-14 19:44
A bit above that though
yacovm
2016-10-14 19:45
In the serve method
donovanhide
2016-10-14 19:46
Guess, you’d have to look at:
https://godoc.org/google.golang.org/grpc/credentials#TransportCredentials
Or maybe:
https://godoc.org/google.golang.org/grpc/credentials#TLSInfo
Don’t know for certain, but it will be in there somewhere :slightly_smiling_face:
yacovm
2016-10-14 19:46
Ok
donovanhide
2016-10-14 19:47
Hope that helps with some ideas :slightly_smiling_face:
yacovm
2016-10-14 19:49
It might, i dunno. I hope i can find the time to play with it a little. I was thinking of simply employing a standard handshake protocol with the gRPC messages and that's it but if we can extract the pub key from the ssl session underneath that's better
donovanhide
2016-10-14 19:50
It’s not the public key, but a hash of all the messages sent and received during the TLS handshake.
yacovm
2016-10-14 19:50
Knowing the session symmetric key doesnt help
yacovm
2016-10-14 19:50
Because we need to know who the peer that connected to us is
donovanhide
2016-10-14 19:51
>>Basically, this is what ripple does: every peer has a self-signed certificate, they establish TLS connections with each other, and then sign the peer finished message (openssl equivalent of tls-unique) using their application level private key.
yacovm
2016-10-14 19:51
How does the signing of the peer finishes message help us?
donovanhide
2016-10-14 19:52
It’s a unique value to that particular network connection. If a peer signs it with its private key. You know who the peer is and that it told you that over a secure connection.
yacovm
2016-10-14 19:53
How can you know who the peer is?
yacovm
2016-10-14 19:54
It tells the TLS layer that, not to the gRPC layer
donovanhide
2016-10-14 19:54
Because it sent you a signature of the hash of the TLS stage and it’s public key via GRPC.
donovanhide
2016-10-14 19:55
This is how ripple works, I’m not making it up :slightly_smiling_face:
donovanhide
2016-10-14 19:55
Except they are still using old protobuf :slightly_smiling_face:
yacovm
2016-10-14 19:57
That's what i'm missing here- who gets the public key via gRPC? surely not the application above the gRPC, right?
donovanhide
2016-10-14 19:58
donovanhide
2016-10-14 19:58
It’s now done via HTTP headers, but it did used to be over protobuf.
yacovm
2016-10-14 19:59
But protobuf is above the gRPC isn't it?
donovanhide
2016-10-14 19:59
GRPC is pretty much protobuf v3
yacovm
2016-10-14 20:00
Ok so you're saying the authentication logic is in the *application layer* and involves sending the pub key
donovanhide
2016-10-14 20:01
Yes! And a signature of the hash of the TLS stage.
donovanhide
2016-10-14 20:01
See `Session-Signature` in the last link.
yacovm
2016-10-14 20:02
Oh so you can verify that sig with the pub key sent via the grpc
donovanhide
2016-10-14 20:02
Yes.
yacovm
2016-10-14 20:02
Got it
donovanhide
2016-10-14 20:02
Great :slightly_smiling_face:
yacovm
2016-10-14 20:03
Still i don't think this exists in go grpc, i'd like to know i'm wrong, but thanks for the tips
yacovm
2016-10-14 20:03
I'll try to find the time to play with it
donovanhide
2016-10-14 20:06
Worth tracing the code back from here to see what is actually does:

Just want to clear up my understanding of chaincode. If I’m running Docker (in my case Docker In Docker on Kubernetes…) and I want to register a chaincode to run on it, I need to `go build` that chaincode on the same architecture that the Docker image will be running, which I’m assuming is linux-amd64. Will I be able to cross compile from an OS X machine using `GOOS` and `GOARCH` and then register that chaincode? Seems you have to run the built chaincode to do the actual registration, so I’d still need a linux box or vm to register?
donovanhide
2016-10-16 15:41
I realise this isn’t a problem if I’m using vagrant :slightly_smiling_face:
muralisr
2016-10-16 15:46
@donovanhide the peer will do the `go build` and package for docker. Everthing else you say above would appear the follow from that
muralisr
2016-10-16 15:46
`—peer-chaincodedev` is the only mode wher the user would have to do `go build` of the chaincode
muralisr
2016-10-16 15:48
With all the SDK work, the ground might shift but the above is w.r.t to current release
donovanhide
2016-10-16 15:53
@muralisr Thanks for the reply :slightly_smiling_face: Still a bit confused though.. Say I’ve got 5 peers running using PBFT on kubernetes, each in a linux based docker image. I have docker in docker running on that same kubernetes rig. I have some local chaincode on my OS X box and a `peer` built locally. How do I get that source code to run on the docker in docker container? Do I have to transfer the source code to one of the remote peers? Sorry, just a bit confused by the docs:
http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#running-the-chaincode
muralisr
2016-10-16 15:54
no worries! I understand its not as clear as it could/should be… let me look up the link to get the context first
muralisr
2016-10-16 15:56
right . if you check `--peer-chaincodedev` is used in all the examples there
muralisr
2016-10-16 15:56
that’s the dev mode where the responsible for building and starting the chaincode
muralisr
2016-10-16 15:59
when that flag is not used, the deploy transaction would be used by the peer to build and constructe chaincode docker image and run it in a docker container. And as any normal transaction process, the deploy transaction is distributed from the peer to which it was sent to to all others in the chain who will do the the identical processing
muralisr
2016-10-16 16:00
as an example, you should see no mention of `—peer-chaincodedev` in this http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Network-setup
donovanhide
2016-10-16 16:03
So my local OSX peer must be running and have awareness of at least one peer node in the remote kubernetes rig? What’s the actual sequence of commands to get my local chaincode running locally, and then deployed to all other peers? Feels like that bit is missing from the page you linked.
muralisr
2016-10-16 16:05
right. let me take chaincode stored remotely as a simpler starting point (the problem is with the “local” chaincode on filesystem which we can take as next step)
muralisr
2016-10-16 16:06
if you use `CORE_PEER_ADDRESS=myknownpeer:7051 peer chaincode deploy -p https://github.com/me/mychaincode`
muralisr
2016-10-16 16:06
you point myknowpeer to code on a remote github which it pulls on the fly and builds
muralisr
2016-10-16 16:07
and that transaction is sent to all peers
donovanhide
2016-10-16 16:07
Ahh, remote github links for code deployment to docker. I think my brain had skipped that part...
muralisr
2016-10-16 16:07

2016-10-16 16:07
you are absolultely on the right track..bear with me for a bit
muralisr
2016-10-16 16:08
the problem is if its on your “local” system (as opposed to remote github for CORE_PEER_ADDRESSed peer to pull the chaincode from)

then the obvious approach is to treat your local box as a a “non-validating peer” (which will go away - at least as of now - in v1.0) and use it just to construct the transaction with the chaincode to be distributed to the actual “validating” peers
muralisr
2016-10-16 16:10
Or
muralisr
2016-10-16 16:12
you could package that common code into each of the peer’s filesystem and use the “deploy” to access it directly on the filesystem (as opposed to pulling it from https://github.com) and then proceed to package for docker as usual

Ok, thank you very much! That clears up my understanding a lot! I prefer the first of the two options for now.

I am currently trying to document crypto mechanisms involved in Fabric in different areas and processes of the ledger activity. I was sweeping through the source code in /master/core/crypto and I found references to : (1) client_confidentiality.go (2) node_tca.go (3) hash.go (4) ecdsa.go (5) x509.go. There's more references to cryptographic mechanisms in /fabric/core/crypto. Unfortunately, none of these pieces of code are documented or commented and therefore, I do not know what they serve for and in what order should I analyze them. Can anyone help me understanding what is used and when?

@donovanhide more to your point though, not sure about the logging component… the package being completely outside of chaincode. But I can see why we’d want that

The developer preview on Bluemix has had some issues (I think new fabrics have patches for these as of this week) and we got a number of divergent block chains. I have been obsessed with the need for a quick way to find the divergent block and decode the transactions, gathering all data from all peers into one message. I really got into in on the weekend and finished it up today. Here is the node-red flow (with 3 sub flows) for that: https://github.com/ibm-watson-iot/blockchain-samples/tree/master/testing/node-red/fabricDivergentBlockFinder ... use this to quickly diagnose your divergence issues. If there are errors on one or more peers, you may be experiencing the issues we've been seeing. But if there are no transaction errors and your hash diverges anyway, then look to your chaincode as a possible (more likely probable) source for the divergence (as in non-deterministic behavior.)
muralisr
2016-10-17 20:52
@kletkeman so a tool that’ll walk through the blockchain on different peers and point to points of divergence (and follow them recursively) ?
kletkeman
2016-10-17 20:54
@muralisr Not sure what you mean by recursively. It polls all configured peer urls for the /chain and verifies first that the height is the same (might be in between catch ups) ... then is so, it proceeds to verify the hashes. If they are the same, then it does nothing else. If they differ, then it performs a binary search to find the first block with hash divergence. I would call it iterative rather than recursive.
kletkeman
2016-10-17 20:55
@muralisr And it does not work on today's Bluemix fabrics because the urls shown in the dashboard send it to the web page, and that's what the tool gets back.
kletkeman
2016-10-17 20:57
@muralisr The response message sorts all output to be the same order as the config URLs ... so vp0 to vp3 for example ... it shows hash and prevhash separately for convenience (to prove that it is the dirvergent block) and then summarizes and decodes the chaincode ID and transactions to speed up diagnosis.
muralisr
2016-10-17 20:59
thanks for sharing @kletkeman … this needs to be checked out for sure!
kletkeman
2016-10-17 21:00
@muralisr Glad you like it ... I enjoyed the node-red education and have been pining for such a tool. I want to run in parallel with our IoT contract long term tests so that we can prove deterministic behavior etc ...

@muralisr I've been reducing the timeouts by looping in node-red at 2s intervals. I find that the tool can get the headings and read 8 blocks (the maximum it takes to find the culprit block with 118 chain height) in something like 20s. Basically, I launch the 4 GETs in parallel, and each of those is funneled to a node that stores the result at flow level. A second path loops through a delay 2s node and checks the result until it sees the correct array length. I'm having a bit of trouble with the terminating condition when you never receive the last result, but I will work on that. For now, that is a pretty rare event.
kletkeman
2016-10-18 13:18
@garisingh If you are referring to my comment on Mluemix 0.5 having issues, we have been unable to use Bluemix for weeks because of instability and chain corruption. We determined that the corruption was coming from timeouts in the network and early attempts to use the chaincode that was taking between 10m and 20m to deploy successfully. I've forwarded that evidence to Mihir weeks ago. I'll paste an example of the output of this tool (just logs for now), which shows a perfect example of the corruption that starts at the 28th block ...
garisingh
2016-10-18 13:24
oh - I thought you were saying that the tool would not work on BMX
garisingh
2016-10-18 13:25
due to lack of function in BMX as opposed to stability
kletkeman
2016-10-18 13:25
@kletkeman uploaded a file: https://hyperledgerproject.slack.com/files/kletkeman/F2QQ5BZTL/divergentblocksolutionbmx.txt and commented: This is the output of the tool for the following fabric: https://new-console.ng.bluemix.net/services/632bf9b3-8a69-4022-81b4-dcea34a11bf3?ace_config=%7B%22orgGuid%22%3A%226f5fa8a7-4207-4f63-b5c6-1c28c1765f67%22%2C%22spaceGuid%22%3A%2294f3d724-41ee-468d-9c1b-18cff83540cc%22%2C%22redirect%22%3A%22https%3A%2F%2Fnew-console.ng.bluemix.net%2F%23all-items%22%2C%22bluemixUIVersion%22%3A%22Atlas%22%7D
It shows the error clearly in the transaction results output. State is written for a failed transaction, which of course corrupts the chain by diverging the peers.
kletkeman
2016-10-18 13:27
@garisingh Ah ... sorry, I was probably not quite clear. BMX works great normally, but there have been stability issues for a while now, which of course might be solved with the new fabrics that get created as of Monday. I have one of those now and will be working with it for the next several weeks.

@kletkeman uploaded a file: https://hyperledgerproject.slack.com/files/kletkeman/F2UEV1SKV/pasted_image_at_2016_10_26_11_51_am.png and commented: We are running long term load tests on a Bluemix peer and have found that, on a busy chain, it is essentially impossible to get the same chain height on all four peers at the same time. I have tried dozens of times and the closest I have come is to see the application contact point (vp0) be only 1 block behind ... but that never lasts ... the furthest I've seen is around 20 blocks behind ... there is a lot of hysteresis in that so it acts like a bungee cord. What this meant for my Hyperledger Divergence Monitor was that it could never rely on the chain heights in order to determine divergence. I updated the latest to handle this by calculating the min height and using that for convergence. That way, it will lag a few minutes behind the maximum chain height, but will give the best guess possible at the time as to whether the chain has diverged. See the screen shot for how this actually looks, and try it out here: https://github.com/ibm-watson-iot/blockchain-samples/tree/master/testing/node-red/Hyperledger%20Hash%20Divergence%20Monitor

@damiang recommend you continue using 0.6 …but for completeness with the original issue on master - you’d need to add `CORE_CHAINCODE_MODE=dev` to the deploy command to run in dev mode so something like `CORE_PEER_COMMITTER_LEDGER_ORDERER=0.0.0.0:5151 CORE_CHAINCODE_MODE=dev peer chaincode deploy -n mycc -c '{"Args":["init","a","100","b","200"]}’`

Hello, a curious newbie here. reading from the protocol-spec, it says the transaction is encrypted with sophisticated key derivation functions to ensure only intended participants may see the content. But if it's encrypted, how can other nodes verify that the transaction is valid?

garisingh
2016-10-27 09:47
@prodia - honestly at this point I would ignore the encryption stuff (and frankly the protocol spec). Work is underway on the V1 release and architecture and that is more relevant. To answer your question, in the current architecture (v0.6 release), all nodes execute and validate all transactions and therefore all have access to the contents of the transactions

I am trying to test the Fabric v0.7 of the orderer function. In order to use the orderer function, I need to explicitly type "make orderer".
Do you have any reason that makefile dose NOT make orderer binary with just type 'make'? If so. I will send a fix patch.

Hi. I am trying to develop a digital ID service with Blockchain tech in Japan. Hope I could use Hyperledger in my product(http://trustdock.io).
What I want to do is to combine the managed PKI technology and Hyperledger PKI to improve the security and usability.
Here are some questions about Hyperledger extended PKI tech. I appriciate if you could answer.
- What is TLSCA? What's the purpose? How it does being used?
- What is ACA (Attribute CA) and ACert (Attribute Certificate)? What is the purpose? How it does being used?
- Regarding the ECA and TCA, should they be certified by root CA? if so, where is the root CA?
- Should root CA be signed by a external CA which is the outsitde of the Blockchain network?
yaoguo
2016-10-28 03:23
@kyrieleison you can see information of TLSCA in `security` part of https://github.com/hyperledger/fabric/blob/master/docs/protocol-spec.md and ACA in https://github.com/hyperledger/fabric/blob/master/docs/tech/attributes.md
yaoguo
2016-10-28 03:25
@kyrieleison you can trust ECA/TCA as root CA

2016-10-28 08:02
As I understand it, ‘Transaction’ in fabric is a request to the blockchain to execute a chaincode.
than, what does it actually mean to ‘validate’ a transaction?

seems like it sends the transaction but then it has an error
anrodon
2016-10-29 23:05

In https://github.com/hyperledger/fabric/blob/master/examples/chaincode/go/asset_management_with_roles/asset_management_with_roles.go it says:
`// Attribute 'account' is used to associate transaction certificates with account owner.`
This sounds kind of funny coming from general blockchains, where a transaction is automatically associated with an account... How should I interpret this statement? Does this have something to do with privileges/privacy?

@jmahhh in HLF, each identity (ECert) is associated to a certain set of attributes (key/value pairs). When creating a pseudonym (TCert), one can decide to export one or more of its attributes. In that example, the attribute 'account' is mapped by the chaincode to a set of assets owned by that account. Does this sound more clear?
zemtsov
2016-11-01 14:34
@adc is this working in 0.6? I try to read attributes with `ReadCertAttribute` in my chaincode, but every time I get the error `Failed retrieving extension.`
adc
2016-11-01 14:36
interesting, just a sanity check: did you enable the aca in the membersrv.yaml?
adc
2016-11-01 14:36
what do you use to send transactions, the node-sdk?
zemtsov
2016-11-01 14:52
@adc I start peers and membersrvc from images with docker-compose
zemtsov
2016-11-01 14:52
@zemtsov shared a file: https://hyperledgerproject.slack.com/files/zemtsov/F2WPS7M6X/-.sh
zemtsov
2016-11-01 14:52
this is my startup file
adc
2016-11-01 14:54
yeah, by default the ACA is disabled
adc
2016-11-01 14:54
so the environment must be changed
adc
2016-11-01 14:54
give me a sec to see how to do that
adc
2016-11-01 14:55
so, you should set MEMBERSRVC_CA_ACA_ENABLED=true
adc
2016-11-01 14:55
or at least, let's try if it works :slightly_smiling_face:
zemtsov
2016-11-01 14:56
@adc should this variable be set for membersrvc?
zemtsov
2016-11-01 14:57
I mean do vps require it?
adc
2016-11-01 15:06
no, only membersrvc

adc
2016-11-01 15:10

adc
2016-11-01 15:10
just last thing, do you use the node-sdk to send transactions?
zemtsov
2016-11-01 15:18
Yes.
adc
2016-11-01 15:18
good, that's the right way
zemtsov
2016-11-01 15:19
I pass a list of attrs to query/invoke requests

@muralisr so @pmullaney and I were just chatting...he mentioned that you were talking about needing to specify the metadata.Version to the chaincode build...that came as a surprise to me
ghaskins
2016-11-01 16:28
i was curious what was driving that?
ghaskins
2016-11-01 16:29
I added the metadata thing to the peer build to version it, but afaik it should only be needed by the peer
muralisr
2016-11-01 16:29
oh … I didn’t mean to say “chaincode"
muralisr
2016-11-01 16:29

ghaskins
2016-11-01 16:29
ah, ok
muralisr
2016-11-01 16:29
right
ghaskins
2016-11-01 16:29
why "go build" and not "make peer" ?
ghaskins
2016-11-01 16:30
fwiw, "make peer" should be synthesizing the metadata parameter for you
muralisr
2016-11-01 16:30
right
ghaskins
2016-11-01 16:30
is there a use case that demands manual override?
muralisr
2016-11-01 16:30
I suggested that as the better alternative to “./peer"
muralisr
2016-11-01 16:31
I think @pmullaney was just used to the `./peer`

so working on https://gerrit.hyperledger.org/r/#/c/2127 and @cbf made the excellent point that we don’t need `generateHashcode` for the car platform (in https://gerrit.hyperledger.org/r/#/c/2127/2/core/chaincode/platforms/car/package.go) now that user is specifying the chaincode name
muralisr
2016-11-01 16:56
Other platforms do need to compute the package but CAR does not even need that

Hi all, I am trying to make a rest call from the to the peer deployed using docker. My chaincode is compiling without errors and I trying to invoke the chain code using a REST client, I am getting the following error message, "code":-32602,"message":"Invalid params","data":"Payload must contain a CtorMsg with a Chaincode function name."
This is the request body,

@vijayr24 I haven't tested this, but I believe you have to change the chaincode ID path to http://github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02 and also add another attribute to the ctorMsg dict of the form "args":["a","100", "b","200"]
oiakovlev
2016-11-02 00:50
@adc QQ regarding discussion above: I realize that SDK is the correct way to issue transations but if we have client already built on top of REST calls can we use attributes from cert or there will be some limitations? again this is PoC and we don't want to rewrite everything and I know that REST has been removed from master already :slightly_smiling_face:
vsbhogle
2016-11-02 05:36
from fabric code I can see that minimum block size is 1024 and maximum block size is 65536....I hope I am right on this..

@oiakovlev unfortunately REST cannot be use to drive those chaincodes, sorry for that :disappointed:

Hi, based on this comment about the GetTxTimestamp() method from the ChaincodeStubInterface:
```
// GetTxTimestamp returns transaction created timestamp, which is currently
// taken from the peer receiving the transaction. Note that this timestamp
// may not be the same with the other peers' time.
GetTxTimestamp() (*timestamp.Timestamp, error)
```
I am not quite sure here, but is it correct to assume that the GetTxTimestamp() is deterministic within a chaincode execution since it seems to be generated by the first peer receiving the transaction (even though it would have been potentially different if initially broadcasted via a different peer)? In other words, can we rely on this to be providing the same consistent value within the chaincode on each of the peers for a given transaction?

Hi everyone! Is anybody use JSON representation of rows and HFC?
I'm using following code to build json
```
var rows []shim.Row
jsonRows, err := json.Marshal(rows)
```
And got something like this as a result in my js code
```[{"columns": [
{"Value":{"String_":"Andrey"}},
{"Value":{"String_":"00112334566"}},
{"Value":{"Uint64":1000}}
]}]```
The question is, how can I (and should I) use the values like "String_", "Uint64" on the client side? May be there is something for automatic type mapping in HFC what I miss?

@rajeshsubhankar. By latest, are you talking about the code from Master branch? may be its because of this https://jira.hyperledger.org/browse/FAB-930? Recently they removed support the REST calls that was part of the peer from master. @jzhang can confirm :slightly_smiling_face:

jzhang
2016-11-03 15:21
@vijayr24 @rajeshsubhankar REST API is disabled by default in master, you can re-enable it by passing an env variable CORE_REST_ENABLED=true, however note that the REST API will eventually be removed from the Peer.
jzhang
2016-11-03 15:22
they are definitely useful but the Peer is not the right place to host it, at least not the APIs that require user identity (deploy, send transaction, query, etc.)
jzhang
2016-11-03 15:22
the SDK team is planning to add a way for REST APIs to be easily enabled based on the SDK library
vijayr24
2016-11-03 15:24
@jzhang: Should I add CORE_REST_ENABLED=true in the docker compose yaml file?

@vijayr24 yes, for the peer service in docker compose
vijayr24
2016-11-03 15:24
Thank you!
jzhang
2016-11-03 15:25
the error above is typically caused by the member service store and client’s keyvalue store getting out of sync
jzhang
2016-11-03 15:26
since you are using the REST API, the “client” in this case is the Peer, so the key value store would be in /var/hyperledger/production. that’s also where the member service store is. so you can delete that folder and re-start the member service and Peer
rajeshsubhankar

The doc suggests March for v1.0, but it could be later. If you're looking to get a project out before then, I'd use 0.6. Just try and avoid the REST API if you can, as my understanding is that it won't work if you update to v1.0 later on

@grapebaba @pd93 I think the only thing we can say definitively is that you will be best positioned if you model chaincode data as JSON. This will ensure support whether using key/value state database or JSON document state database (such as CouchDB), which provides query function against the chaincode (JSON) data

logging:
peer: warning
node: info
network: warning

Can someone point me to a doc that explains what each one of `peer`, `node`, `network`, `version` means?

@ghaskins uploaded a file: https://hyperledgerproject.slack.com/files/ghaskins/F2ZC1A0S3/-.c and commented: for this patch, goimports tells me to remove the os import….lovely

ok, I got past it in a weird way, and its not the first time i’ve seen this
ghaskins
2016-11-04 21:16
it seems sometimes goimport throws an error for perfectly fine code…but if you correct it with gofmt first, gofmt makes a different recommendation and then goimport passes
ghaskins
2016-11-04 21:16
chalk that up to “golang experience”, I guess

@cbf @sheehan any memory of why we dont run gofmt in the linter?
ghaskins
2016-11-04 21:18
it seems (from a data sample of 3) that gofmt is more reliable than goimports, heh
cbf
2016-11-04 21:18
I don’t recall…. it could be because everything was in such bad shape;-)

ghaskins
2016-11-04 21:19
ill experiment with doing a full pass
ghaskins
2016-11-04 21:19
i have a patch to clean up the linter logic anyway
sheehan
2016-11-05 02:21
I think it's because `goimports` includes `gofmt`
ghaskins
2016-11-05 02:26
@sheehan ah, ok...it seems to give different results though
ghaskins
2016-11-05 02:26
could be the way its being invoked I suppose
sheehan
2016-11-05 02:26
yeah, I think there are some extra flags on one of them
ghaskins
2016-11-05 02:26
or perhaps a discrepancy between the gofmt binary and the one embedded in goimports
sheehan
2016-11-05 02:29
`gofmt` has a `-s` flag which is `Try to simplify code (after applying the rewrite rule, if any).` I know some gofmt tools automatically run it with the `-s` flag. I believe it's not possible to include the `-s` flag with `goimports`
ghaskins
2016-11-05 02:29
ah, thats probably what it is
ghaskins
2016-11-05 02:30
in any case, it seems that goimports/gofmt-s might have a bug
ghaskins
2016-11-05 02:30
i have seen this before where it will strip imports that are actually used, resulting in code that wont compile
ghaskins
2016-11-05 02:30
workaround was to run gofmt -w first and then goimports
sheehan
2016-11-05 02:36
that's odd. I would have assumed goimports essentially ran that same command before fixing the imports

Is it possible to not use `membersrvc.yaml` or use another name instead such as `membersrvc2.yaml`? Currently it seems like it is hardcoded in `server.go` I have two different projects that should ideally use two different files

Hi, will this Docker image [https://hub.docker.com/r/hyperledger/fabric-membersrvc/] be changing soon, given the repository split? If so, would it be possible to save the current `latest` (Last pushed: 20 days ago) as a separate tag? Many thanks.
garisingh
2016-11-09 15:19
@mikezaccardo - no - it won't be changing - and it's already built off of the v0.6.1-preview tag
garisingh
2016-11-09 15:20
it's pretty much the last we should push unless we find a defect
garisingh
2016-11-09 15:20
unless @ghaskins disagrees :wink:
ghaskins
2016-11-09 15:20
@mikezaccardo really, the :latest tag needs to probably go away, but there was stuff that broke without it so I put it back for now
ghaskins
2016-11-09 15:21
but that said, the root of your question about saving it off: it already is
ghaskins
2016-11-09 15:21
we explicitly tag everything first anyway (as @garisingh mentioned)
ghaskins
2016-11-09 15:22
@garisingh it is my understanding that the general community doesnt have any intention of pushing any more v0.6 releases
ghaskins
2016-11-09 15:22
whether that is a tenable for all is another matter, I suppose
ghaskins
2016-11-09 15:23
(for instance, I am not sure if there will be too large of a stability gap between v0.6.1 and master to make that realistic)
ghaskins
2016-11-09 15:24
my gut feeling is, its not realistic...but I also can appreciate the desire to focus on the new
garisingh
2016-11-09 15:24
sure - but specific to membersrvc we should not have another build unless we find some bugs

Yes, this means you are running a query before the deployment has finished

At least, I got that error for that reason in the past. Alternatively it means that your deployment failed entirely.

mikezaccardo
2016-11-10 15:31
@axc Like what @jackkleeman mentioned, I’ve seen that problem as well when querying too early. Increasing the sleep time between deploy and query should solve the problem (assuming everything else is set up and deployed properly).
garisingh
2016-11-10 15:33
@mikezaccardo - if you have some ideas on starting something up, that would be great. we did a couple examples from an IBM perspective but we've been looking for a community home as well. We have a few of our apps and chaincodes at https://github.com/IBM-Blockchain
axc
2016-11-10 15:36
@mikezaccardo I am running the asset management with roles example straight from Github, it comes with its own unit tests and I didn't change anything. So it shouldn't have been a problem
mikezaccardo
2016-11-10 15:44
@axc My first thoughts are that the sleep values set in that test are insufficient for you cluster size or CPU resources

Hi, I’m attempting to split the asset management demo [https://github.com/hyperledger/fabric/tree/master/examples/chaincode/go/asset_management] into separate applications, one for each step: deployment, ownership assignment, and ownership transfer.
The first application runs fine, but the second one fails — I’ve figured out that it’s because I need to generate another TCert for the “bob” user, but it's not the same as the one generated in the first application, performed here: [https://github.com/mikezaccardo/fabric/commit/a7471d8ecb873533fa82233fab7f9c167ce26820#diff-6ae780dac4abd9e4c1e7f0530474b734R55].
Is there an elegant way around this problem? Should I serialize the TCert that is created in the first application? Or perhaps I’m not undestanding the cert model properly. Thanks for any help!

3. Host or deploy it separately.

Now, as for Docker (which has kinda become the “market standard” way of approaching virtualization/versioning, at least in the DevOps and “dev” world…)
jonathanlevi
2016-11-11 15:57
You can either use these directly (images are published to docker hub… that you can extend)
jonathanlevi
2016-11-11 15:57
Or you can build custom ones yourself. The latest (master) is using Ubuntu 16.04, but this should not prevent you from using it, say, with Red Hat.
jkilpatr
2016-11-11 15:58
already half way to building a custom one, can't link rocksdb
jkilpatr
2016-11-11 15:58
looks to me like api issues, so I probably just need to dig into the existing dev image and find their exact version of rocksdb
jonathanlevi
2016-11-11 15:59
I don’t want to use this forum for marketing our (Hacera) framework, but we have our own set of build and local tests, always checking the stuff that we are using in fabric - so that whenever/before we “upgrade” the underlying, we verfiy that what we rely on, works.

Oh, in that sense, yes - you can simply look at how the dependencies are being resolved. That’s just a small (technical) bump in the road...
jonathanlevi
2016-11-11 16:00
You can (already) use it outside the box, but yes, for a local/custom build - you’d have to work this out.
jonathanlevi
2016-11-11 16:00
But if you share some of the exact errors, I/we might be able to assist more.

I've read most of the docs I could find and a couple of the research papers. I get the concepts but I'm missing details, so fabric does the actual communication and you can plug in different security methods (POW, POS, then this sawtooh lake stuff)
jonathanlevi

jonathanlevi
2016-11-11 16:06

jkilpatr

I guess the doc I'm looking for would be "shipping your frabic based app" and a list of the minimum things you need to do to get somthing shippable. I don't really need that at this stage but I don't get a -> b there.
jkilpatr
2016-11-11 16:07
what does fabric come with by default, what do I need to add? what components does it depend on?
jkilpatr
2016-11-11 16:07
that sort of junk.
jonathanlevi
2016-11-11 16:10
Yes, my suggestion is to focus first on the core fabric features. The plugable architecture is something that’s in the making (for v1.0).
jonathanlevi
2016-11-11 16:11
CORRECTION: That’s not `junk`, these are the important details! I think you are asking the right questions.
jonathanlevi
2016-11-11 16:11
Hmmm (thinking).
jonathanlevi
2016-11-11 16:11
Do you have a use-case that you want to see how you can develop/implement using Fabric, say?
jonathanlevi
2016-11-11 16:12
Otherwise, maybe a better overview will be useful?
jkilpatr
2016-11-11 16:13
not really. I probably just need to sit down and spend a day or two mapping everything out, all the containers don't help on the dev level because its hard to tell when we are using a container to handle dependencies and when we are using a container to simulate another machine that would be part of the network.
garisingh
2016-11-11 16:14
@jkilpatr - I look at things this way:
1) Fabric provides the basic blockchain infrastructure platform
2) Chaincode gives Fabric a purpose - meaning you might implement chaincode which does commercial paper, car leasing, mortgage, etc
3) The various SDKs (Node and Java (in progress)) allow you to build applications which interface with the Fabric and your chaincode
garisingh
2016-11-11 16:15
if you break out 1), you'll have a bunch of participants who are hosting Fabric nodes
jkilpatr
2016-11-11 16:15
so chaincode is a set of transactions and responses / actions on the part of the network? I read that paper and found it interesting.
jkilpatr
2016-11-11 16:16
ok so programs built on fabric are one network with many different chaincode implementations or are they different networks with different chaincode?
garisingh
2016-11-11 16:22
You'll basically have a bunch of companies and/or individuals who get together and decide to solve a business problem and/or create a new business using blockchain technology. When they choose Fabric, a bunch of them will decide to actually run the "nodes / peers" which make up the network. They'll build and deploy chaincode to solve their business domain and then build applications which submit transactions / query the blockchain for data.
There's nothing which would prevent a single network from serving multiple business domains, it would all depend on the needs / business models of the participants for any given network. Of course some industries have regulations which would inherent require a more closed / private network so you'll end up with multiple networks in the end
jkilpatr
2016-11-11 16:24
ok that explains a lot, thakns @garisingh, i think some of my issue was trying to categorize a meta-project into doing one thing

Hi everyone, I got a small question when I learn the fabric. In the tutorial, it indicate that I should run the chaincode in the CLI and then deploy it. I would like to know if I shutdown the machine which running the chaincode application, of course there are still other peers running in the network, could I still be able to using the function of the chaincode? like invoke and query
yacovm
2016-11-12 13:07
the chaincodes run for each peer alive
yacovm
2016-11-12 13:07
so if you shutdown a peer and its chaincode container, you still have the others
yacovm
2016-11-12 13:07
but keep in mind- if you use PBFT you need to shutdown up to `f` peers, else you'll be in trouble
wangbin767
2016-11-12 13:08
what if I shutdown all the peers and restart them, do I need to redeploy the chaincode? or just be able to use the chaincode as soon as the peers back to live
yacovm
2016-11-12 13:10
hmmm actually I don't know, never tried that before.
wangbin767
2016-11-12 13:11

wait until someone answers, I guess
wangbin767

just curious about the whether do I need to keep the chaincode application running on any one of the peers
garisingh
2016-11-12 14:26
Chaincode deployed in production mode should stay running
garisingh
2016-11-12 14:26
If it goes down, the peer should restart it the next time it is invoked / queried
ghaskins
2016-11-12 15:36
It probably should be noted that there are various degrees of "should" and "what it does in version x"
ghaskins
2016-11-12 15:37
But I think we all agree that the end goal is, operators need not be concerned with this: the peer will manage the platform

Just not sure that will all work today

help me how to check ip and port of peer
madhavi
2016-11-14 09:26
if u start one peer i think no need of giving any ip or port right?
ankitkamra
2016-11-14 09:29
yes if you starting single peer there is no need to give ip
ankitkamra
2016-11-14 09:29
are you using docker-compose or using CLI ?

Hi guys, I'm running into problems when trying the `peer chaincode` commands as specified in the documentation at: http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#running-the-cli-or-rest-api when using the Vagrant setup (option 1), so I was wondering if there are currently any known issues with that setup?
5erj
2016-11-15 00:46
specifically `peer chaincode deploy` seems to require a path parameter `-p` to successfully run.
5erj
2016-11-15 00:47
and `peer chaincode invoke` is throwing the following error:
```
Error: Error endorsing chaincode: rpc error: code = 2 desc = Error deploying chaincode: Failed to launch chaincode spec(Could not get deployment transaction from LCCC for mycc - Error deploying chaincode: Transaction or query returned with failure: transaction not found default/mycc)
```
5erj
2016-11-15 00:48
(note: running peer in dev mode with security not enabled)
muralisr
2016-11-15 00:55
@5erj are you running in master ?
muralisr
2016-11-15 00:56
or 0.6 ?
5erj
2016-11-15 01:49
@muralisr Running in master.
muralisr
2016-11-15 02:00
@5erj can you paste the deploy command you are using
muralisr
2016-11-15 02:00
?
5erj
2016-11-15 02:19
@muralisr `vagrant@hyperledger-devenv:v0.2.1-7e7e23c:/hyperledger/examples/chaincode/go/chaincode_example02$ peer chaincode deploy -n mycc -p . -c '{"Args": ["init", "a","100", "b", "200"]}'`
5erj
2016-11-15 02:20
I had to include the `-p` param because the command was requiring it.
5erj
2016-11-15 02:20
here's what I see on the running chaincode output:

@5erj uploaded a file: https://hyperledgerproject.slack.com/files/5erj/F31RU16TS/-.txt
muralisr
2016-11-15 02:21
can you try `CORE_CHAINCODE_MODE=dev peer chaincode deploy -n mycc -c '{"Args": ["init", "a","100", "b", "200"]}’`
5erj
2016-11-15 02:22
should I restart the peer and chaincode first?
muralisr
2016-11-15 02:23
yes
5erj
2016-11-15 02:25
yep, that went through. So do I have to start the peer, chaincode and run the commands in the same shell session?
5erj
2016-11-15 02:27
(assuming that starting the peer in dev mode sets that variable already in the shell)
5erj
2016-11-15 02:28
The `invoke` still throws the same error though.
muralisr
2016-11-15 02:31
are you running the orderer ?
5erj
2016-11-15 02:31
nope

@muralisr uploaded a file: https://hyperledgerproject.slack.com/files/muralisr/F31SUN4P3/simple_test_with_skeletal_peer.md and commented: I really suggest you use 0.6 while the master is being worked upon.. but the above should help you try out the limited capabilities
muralisr
2016-11-15 02:34
you don’t need `CORE_CHAINCODE_MODE=dev` in 0.6 in `peer chaincode deploy ….`
5erj

@sukhoi the master branch is a work in progress for v1. You need to checkout the v0.6 branch if you're working with membersrvc still.
`git checkout v0.6` should do it

Regarding to a query timeout.
Our current chaincode is really heavy, and we need to do a lot of thing during query.
The question is, whenever the query take too long, probably more than 30 secs. we always got the segmentation fault, and crash the validator node.
Any suggestion on this?
Note: we currently use 0.6 branch.
ghaskins
2016-11-18 02:59
crashing the node is a bug regardless, so please file a jira

I have some other questions,
1. Is it possible to getState() concurrently? is there any lock? Can I actually getState in parallel?
2. For every single chaincode, we will get its chainhash once deployment. However, in the case that we need to modify the chaincode, we will have a different hash. The question is that, how can we retain those states from the old chaincode to the new one. Is it possible to do?

Can anyone comment on if any of the SDKs (e.g. fabric-sdk-node, fabric-sdk-py, etc) are reasonably complete, enough to successfully run a user-authenticated end-to-end test? I'm trying to figure out the most reasonable path to running user-authenticated chaincode on a peer network.

@vdods - not exactly sure what you are trying to do? I'd say that if you wish to use V1 (the code in master) then the answer is probably not quite yet (but might be good to start). With v0.6.1, the answer is yes (but note that the node-sdk is actually in the fabric repo in v0.6.x)

kaustubhoak
2016-11-20 04:20
1. The "path" for chaincode needs to be "path": "https://github.com/kaustubhibm/learn-chaincode/finished" and NOT "path": "https://github.com/kaustubhibm/learn-chaincode/blob/v1.0/finished"
kaustubhoak
2016-11-20 04:21
looks like the chaincode deployment from a branch other than "master" of relevant github repo does not work
kaustubhoak
2016-11-20 04:23
2. "chaincodeID": {"name": "mycc"..... does not work and has to be "chaincodeID": {"name": "<CHAIN CODE ID from the response of an earlier chain code deployment invocation>"

Hi ,
We are running fabric in prod mode which requires the git repo path at the time of chaincode deployment.
Currently we are unable to deploy the code from a private git repo. Is there a way around this? Could anybody please help on this issue?
Thanks

Hello! I'm running fabric through CLI with `docker run`. I created instance of class where I run one peer, and sending and getting messages. The question is: why when I'm getting messages from root peer I got every message I invoke through all peers, but when I'm getting messages from not root peer, I am getting only those messages, that I invoke to this peer. Info on blockchain should be kept on all peers, isn't it?

Hello, I'm running this SDK-node example https://github.com/hyperledger/fabric-sdk-node/blob/master/docs/sample-standalone-app.md. In this example the chaincode deployed,invoked and queried from node.js applicaiton
Actually, it works only once. Next time, when I restart the peer and membersrv the admin user is rejected. I found some kind of "work around" by changing admin to admin1,2,3,4... in membersrv.yaml file, but it not always works. So how to register an admin for second time?

How is the core.yaml configuration for a Non Validating Peer connecting to a HTTPs/gRPCs Validating Peer/Memberdhip, can anyone help me with this?
lipets
2016-11-22 16:08
The latest fabric in github does not contain "membersrv". Why? Where can I get it? (I need it for sdk-node and sdk-java samples)
garisingh
2016-11-22 16:11
@lipets - why not just use the Docker images we publish already?
garisingh
2016-11-22 16:11
other option is to checkout that v0.6 branch rather than master
garisingh
2016-11-22 16:12
master is where v1.0 work is taking place and membership services is replaced by fabric-cop which has its own repo
garisingh
2016-11-22 16:12
the SDK samples you are looking at are likely for v0.6 in any case
lipets
2016-11-22 16:14
@garisingh, thank you. Where it is published? I'm using vagrant. Is 0.6 compatible with 0.7+membersrv that I already have?
garisingh
2016-11-22 16:17
hmm - I'll be honest - I'm not familiar with v0.7 - but I'll say the answer is yes if it is still using membersrvc
lipets
2016-11-22 19:48
@garisingh, thank you. I started docker using instructions from here https://github.com/hyperledger/fabric/blob/master/docs/Setup/Chaincode-setup.md (Running the Peer and CA). It runs, but it seems that there is no response at all on port 7054
cbf
2016-11-22 19:53
@lipets you should play with the starter-kit here… should be no need to build from source
lipets
2016-11-22 20:06
@cbf, thank you, It works! Also i was able to install branch v0.6 with vagrant and start node test application. What I can't - is running fabric-sdk-java samples...
cbf
2016-11-22 20:58
@lipets I am not sure which commit level is matched with the v0.6 release - you should ask on the #fabric-sdk-java channel

Dear Gents, does anyone know how to configure the docker-compose.yaml to have a Starter (starter1:
container_name: starter1
image: hyperledger/fabric-starter-kit) stating up my chaincode? But I need this for 4 peers, and not only 1. Does this mean I need 4 starters?
bercinho
2016-11-23 13:39
I want to have vp0, vp1, vp2, vp3 all running on the same node, with PBFT consensus and having the starter(s) to kick off the chaincode in each of them.
bercinho
2016-11-23 13:39
Many Thanks
tuand
2016-11-23 14:06
@bercinho, in the hyperledger/fabric/bddtests directory, there are docker-compose yml files that start up 1 to 4 peers. You can use these as examples for what you need to do
bercinho
2016-11-23 14:55
Hi
bercinho
2016-11-23 14:55
Thanks for the info. But these don´t use the starters
bercinho
2016-11-23 14:55
this part
bercinho
2016-11-23 14:55
starter1:
container_name: starter1

volumes:
# tweak this to map a local developmnt directory tree into the container

bercinho
2016-11-23 14:56
so I want to understand how to use this (to kick off the chaincode) with multiple peers
bercinho
2016-11-23 14:56
whether I need one starter per peer or just one starter and how to configure
tuand
2016-11-23 15:17
@bercinho you'll want to tweak hyperledger/fabric/examples/sdk/node/docker-compose.yml to add the peers ( use the hyperledger/fabric/bddtests files to see how the peers are configured). You don't need to edit the starter service definition
bercinho
2016-11-23 15:24
Hi, thanks for response! :slightly_smiling_face: so the starter service will work to deploy the chaincode to all the peers? Do I have to extend the "links" of he starter service to vp0, vp1, vp2, vp3 as well?
bercinho
2016-11-23 15:28
@bercinho uploaded a file: https://hyperledgerproject.slack.com/files/bercinho/F371CFL6B/docker-compose2.yaml and commented: This is my current config, which doesn´t work.
tuand
2016-11-23 15:36
The peer you send a request to will propagate to the other peers so all peers will execute ... the peers do need to link with each other and membersrvc so they should have docker links to discovery_root_node and membersrvc
tuand
2016-11-23 15:36
the starter should have docker links to whichever peer it is sending requests to
bercinho
2016-11-23 15:38
ah ok, cool so the starter only have a link to one peer?
tuand
2016-11-23 15:38
i don't know if your core_vm_endpoint is needed ... otherwise, you'll have to read logs to see why the transaction is not executing
tuand
2016-11-23 15:39
yes, link to vp0 is enough
bercinho
2016-11-23 15:39
ok thanks, I will play around a bit and let you know :slightly_smiling_face:
tuand
2016-11-23 15:40

guys, I found an issue about TLS. Actually the tlsca.cert under bddtests directory is expired. The only valid cert is the one in fabric-membersrvc image under /var/hyperledger/production/.membersrvc

Yup, we wanted to update this but then it got deprioritized somehow. See https://jira.hyperledger.org/browse/FAB-213

yacovm
2016-11-24 09:38
no point in prioritizing it now
jonathanlevi
2016-11-24 09:43
Usually the problem is not the test… (BDD or otherwise).
We should have both positive-flow and negative-flow tests, verifying the correct functionality in case(s) of expired certs. Definitely in fabric-cop. I don’t have a strong opinion at this point about how we really write these tests.
yacovm
2016-11-24 09:47
bdd doesn't work now, at all.
jonathanlevi
2016-11-24 09:56
The fact that the BDD tests are not working “at all” cannot be a good enough reason for not fixing them :wink:
jonathanlevi
2016-11-24 09:56
I say: if we have it, it should work.
jonathanlevi
2016-11-24 09:56
If it should not work/not expected to work - it should not be there.
jonathanlevi
2016-11-24 09:57
There is some work needed both in fabric-cop / membership services and in any component validating these certs.
jonathanlevi
2016-11-24 09:57
A matter of priority, but I don’t think it should be ignored.

how to connect peers from two different system
vigneswaran.r
2016-11-25 06:04
@satyam_agl The following link has some information on that..
https://github.com/hyperledger/fabric/blob/master/docs/Setup/Network-setup.md#start-up-additional-validating-peers
vigneswaran.r
2016-11-25 06:06
@kaavya Do you want to connect peers through CLI method or REST APIs?
kaavya
2016-11-25 06:08
CLI
ankitkamra
2016-11-25 06:11
@kaavya while starting node use switch -CORE_PEER_DISCOVERY_ROOTNODE=<Path to first node>
kaavya
2016-11-25 06:14
In a same system we will give path as docker ip address. I have to configure physical ip address of two system, so that they can discover root nodes. How can I configure this.. Is there any steps to follow?
ankitkamra
2016-11-25 06:14
are you using vagrant or docker ??
kaavya
2016-11-25 06:18
Inside vagrant env we use docker commands to run peers..
kaavya
2016-11-25 06:18
docker run --rm -it -e CORE_VM_ENDPOINT=http://172.17.0.1:2375 -e CORE_LOGGING_LEVEL=DEBUG -e CORE_PEER_ID=vp1 -e CORE_PEER_ADDRESSAUTODETECT=true -e CORE_PEER_DISCOVERY_ROOTNODE=172.17.0.2:7051 hyperledger/fabric-peer peer node start
ankitkamra
2016-11-25 06:19
Okay got it you have to do port forwarding in vagrantfile that exist in devenv directory
vigneswaran.r
2016-11-25 06:20
I think, port forwarding is done by default in vagrant.
kaavya
2016-11-25 06:21
Yes... Its already done
kaavya
2016-11-25 06:21
config.vm.network :forwarded_port, guest: 7050, host: 7050 # Openchain REST services
config.vm.network :forwarded_port, guest: 7051, host: 7051 # Openchain gRPC services
config.vm.network :forwarded_port, guest: 7054, host: 7054 # Membership service
config.vm.network :forwarded_port, guest: 7053, host: 7053 # GRPCCient gRPC services
vigneswaran.r
2016-11-25 06:21
Then you can replace CORE_PEER_DISCOVERY_ROOTNODE=172.17.0.2:7051 with CORE_PEER_DISCOVERY_ROOTNODE=<other_machine_ip>:7051
vigneswaran.r
2016-11-25 06:22
You can specify the other machine (where another peer is running)'s IP (instead of 172.17.0.2
vigneswaran.r
2016-11-25 06:23
I mean the physical machine's IP..
ankitkamra
2016-11-25 06:23
@kaavya Actually you have done port forwarding from host --> guest and there is no port forwarding from guest --> docker
ankitkamra
2016-11-25 06:24
hence it will be able to connect host --> guest --> docker
kaavya
2016-11-25 06:25
how can I do port mapping from guest --> docker ?
ankitkamra
2016-11-25 06:26
use docker-compose
vigneswaran.r
2016-11-25 06:27
If we use docker-compose, then we can do in the following way,
https://github.com/hyperledger/fabric/blob/master/docs/Setup/Chaincode-setup.md#running-the-peer-and-ca
vigneswaran.r
2016-11-25 06:27
eg.,
vp0:
image: hyperledger/fabric-peer
ports:
- "7050:7050"
- "7051:7051"
- "7053:7053"
ankitkamra
2016-11-25 06:28
@kaavya yes you may refer to example given by @vigneswaran.r
kaavya
2016-11-25 06:36
guess in this example using docker compose we are trying to run multiple peers using same docker-compose.yaml file ?
vigneswaran.r
2016-11-25 06:41
true.. but that's an example only. please see the "ports:" part which is used for forwarding the ports. ignore the rest.
vigneswaran.r
2016-11-25 06:43
the docker-compose.yaml in the specific example is meant for running one membership service (membersrvc) and one peer (vp0).
kaavya
2016-11-25 06:47
@vigneswaran.r thank you
kaavya
2016-11-25 06:47
I'll try these..

vigneswaran.r
2016-11-25 08:55
I assume, you are running peer service inside docker image. Have you passed the environment variable CORE_VM_ENDPOINT=http://172.17.0.1:2375 while starting the peer?
vigneswaran.r
2016-11-25 08:57
In my understanding, peer will talk to Docker through CORE_VM_ENDPOINT in order to build docker image, communicate with running chaincode etc.
vigneswaran.r
2016-11-25 08:58
In your case it is trying to talk to docker using the unix socket (instead of through TCP/IP).
ankitkamra
2016-11-25 08:58
yeah i have given CORE_VM_ENDPOINT

I am trying to follow the fabric skeletal workflow for deploying and invoking chaincode..

i am running this peer inside a docker container..

@sadanandu I should have worded it more carefully …. `REST api is removed (not “restricted”) so as the the fabric can be minimal and all access can be controlled via SDKs and other higher layers`
vigneswaran.r
2016-11-28 03:56
@bercinho Sometimes this error comes if we start the peer immediately after starting the membership service. Please give ~15 sec before starting the peer service (by the time the membership service will be ready).
I assume, you are using the correct IP address of the membersrvc node and port number.
sadanandu
2016-11-28 04:01
@muralisr oh...Thanks for the reply...I think I got the point there ...leave fabric to do what is core to it and write API in other higher level abstractions elsewhere

There I was, happy and content that v0.6 was brought into line with v1 fabric so that we could bring our contracts into line with the future API. So I go to build against v1 for the first time and am stunned to find a new API break. And for a simple change to the signature for Init. Was that really necessary?
My point being that we would like to avoid separate source copies for v0.6 (Bluemix) and v1 ...

Hi, i am writing chain code application in Golang and want to create a web UI for it. I found out https://github.com/IBM-Blockchain/cp-web this example . Here they are using mycreds.json to fetch the information regarding peers, ca, users.
This file can be auto generated if you are using IBM blue mix. Since I am developing on local development environment in the HyperLedger fabric , i can't get this file directly. Can someone please help me out and guide how to get around this? I want to use the HFC SDK and this credentials file is necessary for it.

@ankitkamra I hope, you have found the docker configuration file in Centos. Does it contain any entry like the following,
DOCKER_OPTS="-s=aufs -r=true --api-cors-header='*' -H -H unix:///var/run/docker.sock "
vigneswaran.r
2016-11-28 10:38
this essentially says docker to listen on both TCP/IP port 2375 and unix socket /var/run/docker.sock
ankitkamra
2016-11-28 10:45
yes problem is that docker is not listening
ankitkamra
2016-11-28 10:46
i did not find any file with the given entry
ankitkamra
2016-11-28 10:46
let me try
vigneswaran.r
2016-11-28 10:50
ok
vigneswaran.r
2016-11-28 10:55
In centos, the configuration file seems to be /etc/sysconfig/docker
ankitkamra
2016-11-28 10:55
@vigneswaran.r i found the file
ankitkamra
2016-11-28 10:55
and edit deployed chaincode
ankitkamra
2016-11-28 10:55
but again same problem
ankitkamra
2016-11-28 10:55
but this time its listening on 172.17.0.1 2375
ankitkamra
2016-11-28 10:55
i am able to telnet from host machine but not able to telnet from docker images
vigneswaran.r
2016-11-28 10:56
can you copy paste the DOCKER_OPTS in your docker file?
vigneswaran.r
2016-11-28 10:56
we can see if some typo etc..
ankitkamra
2016-11-28 10:57
i have edit docker.service file
ankitkamra
2016-11-28 10:57
as following
ankitkamra
2016-11-28 10:57
ExecStart=/usr/bin/dockerd -H -H unix:///var/run/docker.sock
ankitkamra
2016-11-28 10:58
i found this somewhere
ankitkamra
2016-11-28 10:58
because there is no such configuration file under /etc/
vigneswaran.r
2016-11-28 11:00
ok.. can you see whether this is what actually running? (ps ax|grep dockerd)
This should show you the command being run
ankitkamra
2016-11-28 11:00
yes i have checked it
ankitkamra
2016-11-28 11:00
even its listening on 2375 port
vigneswaran.r
2016-11-28 11:03
try whether docker is listening on /var/run/docker.sock also.. (sudo fuser -v /var/run/docker.sock)
ankitkamra
2016-11-28 11:06
hmm let me check
ankitkamra
2016-11-28 11:08
same problem :disappointed:
vigneswaran.r
2016-11-28 11:08
what is the output of the fuser command?
garisingh
2016-11-28 11:09
@ankitkamra - are you running the peers as Docker containers as well?
ankitkamra
2016-11-28 11:11
@vigneswaran.r can you please specify exact command for fuser ?
vigneswaran.r
2016-11-28 11:12
sudo fuser -v /var/run/docker.sock
ankitkamra
2016-11-28 11:12
@garisingh yes i am running both
ankitkamra
2016-11-28 11:12
@vigneswaran.r

vigneswaran.r
2016-11-28 11:13
can you give the output of "ps ax|grep dockerd"
vigneswaran.r
2016-11-28 11:14
I suspect, the docker is not starting with proper options.
ankitkamra
2016-11-28 11:14
[root@localhost ~]# ps ax|grep dockerd

vigneswaran.r
2016-11-28 11:14
no docker is running??
ankitkamra
2016-11-28 11:14
sorry wait
ankitkamra
2016-11-28 11:14
i got output from wrong terminal
vigneswaran.r
2016-11-28 11:14
ok
ankitkamra
2016-11-28 11:15
[root@localhost ~]# ps ax|grep dockerd
9168 ? Ssl 0:00 /usr/bin/dockerd -H -H unix:///var/run/docker.sock

ankitkamra
2016-11-28 11:15
this is the output
ankitkamra
2016-11-28 11:15
and following is output of fuser command:-
[root@localhost ~]# sudo fuser -v /var/run/docker.sock
USER PID ACCESS COMMAND

vigneswaran.r
2016-11-28 11:15
ok..
vigneswaran.r
2016-11-28 11:16
so, it seems docker is actually listening to /var/run/docker.sock properly..
ankitkamra
2016-11-28 11:16
yes
ankitkamra
2016-11-28 11:17
but not able to telnet to specific port
ankitkamra
2016-11-28 11:17
i dont know why
vigneswaran.r
2016-11-28 11:17
wait
vigneswaran.r
2016-11-28 11:18
change the docker command to /usr/bin/dockerd -H -H unix:///var/run/docker.sock
vigneswaran.r
2016-11-28 11:18
don't put the IP, instead use 0.0.0.0
ankitkamra
2016-11-28 11:18
i had tried this also
ankitkamra
2016-11-28 11:18
even tried with 127.0.0.1
vigneswaran.r
2016-11-28 11:18
please try with 0.0.0.0 once again and try to telnet
ankitkamra
2016-11-28 11:19
okay sure
ankitkamra
2016-11-28 11:20
able to telnet from localhost
ankitkamra
2016-11-28 11:21
not from other machine
ankitkamra
2016-11-28 11:21
its giving following error:-

2016-11-28 11:22
can you check "iptables -L -n -v"
vigneswaran.r

vigneswaran.r
2016-11-28 11:40
@ankitkamra I think, there is some problem with fabric-baseimage tag (latest) specified in the core.yaml (chaincode section).. May be it should be something like "$(ARCH)-$(PROJECT_VERSION)" instead of "latest".. not sure..
Due to that, the chaincode didn't get deployed, and the query fails.

oh @vigneswaran.r so what is you suggestion to resolve the problem ?
vigneswaran.r
2016-11-28 11:45
May be, you can edit the core.yaml (of the peer inside docker image) and look for the tag "latest". Try to change it as per my previous message. However, I am not very sure about this.

ghaskins
2016-11-28 16:27
so is there someone looking at this spate of gossip/* UT failures?
ghaskins
2016-11-28 16:27
@yacovm don't mean to pick on you, but you are the only contact point I know for gossip
ghaskins
2016-11-28 16:27
I am seeing numerous gossip/* failures like: https://jenkins.hyperledger.org/job/fabric-verify-x86_64/3346/console
yacovm
2016-11-28 16:27
which test is it this time
ghaskins
2016-11-28 16:27
gossip/comm in this case
ghaskins
2016-11-28 16:27
though I saw some gossip/state earlier too
yacovm
2016-11-28 16:28
wow
yacovm
2016-11-28 16:28
well,
```
13:48:31 [33munit-tests_1 |[0m --- FAIL: TestParallelSend (0.01s)

13:48:31 [33munit-tests_1 |[0m panic: listen tcp :5611: bind: address already in use
```
Is indeed mine but how is it possible? I use different ports in all the test
ghaskins
2016-11-28 16:29
theres a reasonable chance I need to rebase my patches if there were any recent fixes
yacovm
2016-11-28 16:29
are you running this locally?
yacovm
2016-11-28 16:29
oh right
yacovm
2016-11-28 16:29
no
ghaskins
2016-11-28 16:29
no, this was jenkins
yacovm
2016-11-28 16:29
that's in CI
yacovm
2016-11-28 16:30
yeah yeah it's the time
yacovm
2016-11-28 16:30
I think somehow that port is taken by some other port
yacovm
2016-11-28 16:30
this address already in use is impossible... I use different ports in each test in that file
ghaskins
2016-11-28 16:31
question: why not let the tcp stack pick one for you?
ghaskins
2016-11-28 16:31
ephemeral ports, i mean
yacovm
2016-11-28 16:32
because it's "hard"- how do I know which ports are open and which are not?
yacovm
2016-11-28 16:32
you mean why not bind to 0?
ghaskins
2016-11-28 16:32
right
yacovm
2016-11-28 16:32
heh, it works the other way
yacovm
2016-11-28 16:32
I get the port I need to bind to, from the gossip layer
yacovm
2016-11-28 16:32
the comm layer is underneath the gossip layer
muralisr
2016-11-28 16:32
(as an aside - @ghaskins .. when you say “spate” of failures. … do all have the same issue ? )
muralisr
2016-11-28 16:33
reason I ask is… if so something would be funky given @yakov's `Is indeed mine but how is it possible? I use different ports in all the test`
ghaskins
2016-11-28 16:33
@muralisr I just saw rumblings on the other channels with postings about the cobertura reports...which turned out to be a red herring...when I looked at the root cause of the cobertura error, it was a UT failure in gossip/*
yacovm
2016-11-28 16:33
I have a question- just to make sure: if I have in the same package- A_test.go and B_test.go
yacovm
2016-11-28 16:34
do they run serially?
yacovm
2016-11-28 16:34
well, @ghaskins that was a failure in gossip/state, not mine :wink:
ghaskins
2016-11-28 16:34
@yacovm its not clear
yacovm
2016-11-28 16:34
and Corwin said he'll take a look at it
ghaskins
2016-11-28 16:34
go does support parallel execution of tests, but when/where/if are varialbes
yacovm
2016-11-28 16:35
if it's not clear it's weird because the comm test never failed on *that* and that code has been there for weeks
yacovm
2016-11-28 16:35
I think the binding is a fluke... if it persists I'll try to investigate
ghaskins
2016-11-28 16:35
@ry has mentioned some unusual circumstances when a CI minion can be shared somehow
yacovm
2016-11-28 16:35
yeah, that's a big problem
yacovm
2016-11-28 16:35
for my code
ghaskins
2016-11-28 16:36
perhaps a test was running concurrently @ry ?
yacovm
2016-11-28 16:36
I remember that
yacovm
2016-11-28 16:36
But we need to take into consideration the probability of the tests to run *concurrently*
yacovm
2016-11-28 16:36
for example- if that minion runs the chaincode and the gossip at the same time, it's ok, etc. etc.
ry
2016-11-28 16:37
There should never be concurrent runs
ry
2016-11-28 16:38
What I said is there may be serial runs on one minion
ghaskins
2016-11-28 16:38
ah, right...it was a problem with persistent state
ry
2016-11-28 16:38
The only way I can imagine this happening is if a test hangs and another starts before a recycle
ghaskins
2016-11-28 16:38
I couldve sworn there was some problem with file locking from two things running or something too
ghaskins
2016-11-28 16:39
but maybe I am not remembering that correctly or had misunderstood
ry
2016-11-28 16:39
If a test crashes or something you might leave something locked
ghaskins
2016-11-28 16:39
ah, ok
ghaskins
2016-11-28 16:39
that couldve been it
yacovm
2016-11-28 16:40
ahhh
yacovm
2016-11-28 16:40
really?
yacovm
2016-11-28 16:40
wait how is that possible?
yacovm
2016-11-28 16:40
if a test crashes the process terminates
ghaskins
2016-11-28 16:48
if the underlying environment were reused...
ghaskins
2016-11-28 16:48
as opposed to starting fresh
yacovm
2016-11-28 16:54
but when the test fails the process dies and the port binding dies with it
jackkleeman
2016-11-28 17:42
will I run into any problems having an autorestarting systemd service which runs the peer, runs the chaincode, and sends a deploy command?
jackkleeman
2016-11-28 17:45
does anyone have any scripts that they use to handle the full deploy process?
ghaskins
2016-11-28 18:25
@jackkleeman what do you mean by "runs the chaincode"? it sounds like you are using a --devmode model?
ghaskins
2016-11-28 18:25
in a production environment, the peer would manage the lifecycle of the chaincode
jackkleeman
2016-11-28 18:26
yes devmode model
ghaskins
2016-11-28 18:26
fwiw, I do have a supervisord script that runs a v0.6 setup in --devmode with chaincode
jackkleeman
2016-11-28 18:26
this is because I dont want to keep track of the chaincode id
ghaskins
2016-11-28 18:26
but this is not a natural thing to do
jackkleeman
2016-11-28 18:26
could you send that my way?
ghaskins
2016-11-28 18:27
sure, hold on
ghaskins
2016-11-28 22:04
@yacovm heres one in gossip/gossip: https://jenkins.hyperledger.org/job/fabric-verify-x86_64/3348/console
ghaskins
2016-11-28 22:04
I assume that is different from gossip/state or gossip/comms
yacovm
2016-11-28 22:13
Yep, it's the pull test that failed. I'll take a look tomorrow and see if I can figure out why that happened. It's kinda hard though, even from having stack traces of all goroutines there
yacovm
2016-11-28 22:13
never seen it fail in CI before however
yacovm
2016-11-28 22:20
This is weird though, it "sounds" like a block went missing, which doesn't make sense because the msgStore size is way higher than the amount of blocks I send in the test. The pull algorithm is supposed to have more than enough time to complete the blocks :confused:

@vigneswaran.r @ankitkamra - the concepts surrounding hyperledger/fabric-baseimage are being supplanted by hyperledger/fabric-ccenv. As such, try pointing to this ccenv image in your docker-compose .yaml. Another option is to manually pull the baseimage for your platform and then execute a rename to tag it as baseimage:latest
nickgaski
2016-11-28 22:45
This documentation will be updated shortly, but we can work around it in the meantime
nickgaski
2016-11-28 22:48
for example, ```docker tag hyperledger/fabric-baseimage:x-86x86_64-0.2.1 hyperledger/fabric-baseimage:latest```

@nickgaski Thank you :slightly_smiling_face: , i have one question that where is fabric-baseimage is running, according to documentation we need to pull only fabric-membersrvc and fabric-peer image. And i have already tagged it with latest.
ghaskins
2016-11-29 03:49
@ankitkamra baseimage is used, as the name implies, as the baseimage of most docker images in the system...in v0.6 it is also used directly to compile chaincode
ghaskins
2016-11-29 03:50
in v1.0/master, there is a new image named "ccenv" which takes its place as the environment that we compile chaincode into
ghaskins
2016-11-29 03:50
but the concept is the same, just the name changes
ghaskins
2016-11-29 03:50
the main problem you are seeing is the system is still not yet really equiped to run from anything but from a locally build source environment
ghaskins
2016-11-29 03:51
yes, you can run from docker with a little massaging, but its still not turnkey
ghaskins
2016-11-29 03:51
we are working on that
ankitkamra
2016-11-29 03:52
@ghaskins so should i pull fabric-baseimage too ?
ankitkamra
2016-11-29 03:53
and fabric-baseimage is used by peer only or as well it must exist on membersrvc machine too ?
vigneswaran.r
2016-11-29 03:53
once see what are all the images you have.. (docker images)
vigneswaran.r
2016-11-29 03:53
it may be just a matter of tagging properly
ankitkamra
2016-11-29 03:53
i have two machines, one contains membersrvc image and another contain peer image
ghaskins
2016-11-29 03:54
@ankitkamra yes, for v0.6.1-preview, you want to pull hyperledger/fabric-baseimage:$(arch)-0.0.11
ghaskins
2016-11-29 03:54
and retag it as latest
ghaskins
2016-11-29 03:55
it does not need to exist on the membersrvc node
ghaskins
2016-11-29 03:55
just the peer
ghaskins
2016-11-29 03:56
actually, i think v0.6 only supports x86_64 now that I think of it
ankitkamra
2016-11-29 03:56
okay let me try
ankitkamra
2016-11-29 03:57
@ghaskins and @vigneswaran.r Thanks a lot, i am trying with provided solution, if i face any problem i will get back to you guys
ghaskins
2016-11-29 03:58
@ankitkamra pay attention to the version....v0.6.1-preview uses v0.0.11...the latest is v0.2.1
ghaskins
2016-11-29 03:58
but dont be tempted to use the latest
ghaskins
2016-11-29 03:58
that is not qualified to work together
ankitkamra
2016-11-29 03:59
okay thanks

np, and good luck

@ankitkamra That information will be helpful for others..

2016-11-29 06:12
@vigneswaran.r i was using baseimage v0.0.11. I think that was not compatible with peer v0.6.1-preview. I just pulled out another versions and it is working fine with baseimage v0.2.1

@ankitkamra If you run membersrvc docker image, 172.17.0.2 will be taken by that; First peer will have 172.17.0.3. So, by any chance you mentioned wrong peer IP somewhere?
ankitkamra
2016-12-01 05:52
@vigneswaran.r both docker images are on separate machines so both have the same ip 172.17.0.2

@akashsethi24 has left the channel

oh.. ok

2016-12-01 05:57
@vigneswaran.r so whats your suggestion ? What can be the possible solution ?
vigneswaran.r
2016-12-01 05:58
so both validating and non-validating peers on the same machine, right?
ankitkamra
2016-12-01 06:02
no both are on separate machines
vigneswaran.r
2016-12-01 06:03
then NVP can't reach VP0 by 172.17.0.2 IP right? it should be reached using the machine's IP, isn't it?
vigneswaran.r
2016-12-01 06:04
172.17.0.0 is local to a machine (docker network) right?
vigneswaran.r
2016-12-01 06:06
I think, you are already using membersrvc machine's IP (not the 172.17.0.2) to reach the service from peer on another machine..
vigneswaran.r
2016-12-01 06:06
Similar is the case with NVP to VP (when they run on different machines).
ankitkamra
2016-12-01 06:10
yes nvp can't reach to vp0 by 172.17.0.2
ankitkamra
2016-12-01 06:11
my network is as following:-
membersrvc:- 172.30.65.39
vp0:- 172.30.65.36
ankitkamra
2016-12-01 06:11
nvp0:- 172.30.65.26
ankitkamra
2016-12-01 06:12
and i have give vp0 address as root node address in docker-compose file of nvp
ankitkamra
2016-12-01 06:12
vp0 machine physical ip address
vigneswaran.r
2016-12-01 06:13
since your error message shows 172.17.0.2:7051, I am a bit confused.. From where that information is taken?
ankitkamra
2016-12-01 06:14
both vp and nvp auto detected these address using docker to make communication over grpc
vigneswaran.r
2016-12-01 06:14
oh, ok..
ankitkamra
2016-12-01 06:14
basically both must listen on physical ip
ankitkamra
2016-12-01 06:15
i have changed configurations in peer/core.yaml but it can't assign physical address
vigneswaran.r
2016-12-01 06:15
May be then, we should disable the auto detection of IP..
ankitkamra
2016-12-01 06:15
hmm let me check
ankitkamra
2016-12-01 06:17
i have checked peer/core.yaml in which addressAutoDetect is already false under peer section
vigneswaran.r
2016-12-01 06:17
CORE_PEER_ADDRESSAUTODETECT=true
vigneswaran.r
2016-12-01 06:18
But you may have the above line in your docker-compose.yaml
vigneswaran.r
2016-12-01 06:18
If so, you can comment that
ankitkamra
2016-12-01 06:19
oh yes, i forgot docker-compose file :smile:
vigneswaran.r
2016-12-01 06:20
:slightly_smiling_face:
ankitkamra
2016-12-01 06:20
after commenting it, its still auto detecting ip address

see the logs:-

2016-12-01 06:24
ok.. I think, listening on local IP is fine.. docker will take care of forwarding the port to the host..
vigneswaran.r
2016-12-01 06:25
however, I am not sure how NVP identifies the validating peer's IP.. whether Peer says it? If so, it will tell the 172.17.0.2 IP only (not the machine's IP)..
ankitkamra
2016-12-01 06:26
yes, it is telling ip 172.17.0.2
ankitkamra
2016-12-01 06:26
that both broadcasting through gRPC
vigneswaran.r
2016-12-01 06:27

garisingh
2016-12-01 16:14
@bercinho - you might want to post this over in one of the fabric-sdk-node channels, but a quick guess would be that perhaps the certificates being used by your peer are different than the ones received by the Node client. This might have happened in you've wiped out / restarted membership services, the peer and the client all at different times. Are you running the peer(s) and membersrvc via Docker?
bercinho
2016-12-01 16:17
hi, thanks for feedback. Peer & Membersrvc is running via Docker indeed ... the thing is I am able to interact correctly from my local workstation via the REST APIs (using Postman), but when running Node.JS SDK in Atom I get this problem
garisingh
2016-12-01 16:18
yeah - via REST the peer you connect to acts as the client so it would make sense that would work

I'm trying to get two computers networked so I can add chaincode on one, and query from the other. I see that it's easy to do with two different nodes on the same computer, but I haven't been able to get to machines networked right.
I'm using CORE_PEER_DISCOVERY_ROOTNODE to specify the other computer in my docker-compose.yml. I used a simple python server to make sure that the machines can talk on ports 705x, but I still get errors: [peer] chatWithPeer -> ERRO 056 Ending Chat with peer address 10.101.3.140:7053 due to error: Error creating handler during handleChat initiation: Error creating PeerHandler: Error creating new Peer Handler, error returned sending DISC_HELLO: Error Sending message through ChatStream: rpc error: code = 13 desc = transport is closing. Any suggestions?
ghaskins
2016-12-02 16:18
@webkruncher it sounds like you are using docker-compose but manually running two different compositions?
ghaskins
2016-12-02 16:18
or are you using something like swarm to spread one composition across two nodes?
webkruncher
2016-12-02 16:20
@ghaskins - I'm using docker-compose - nothing manual - what do you mean 'two different compositions'?
garisingh
2016-12-02 16:22
@webkruncher - Docker native on each host or trying to run Docker in Vagrant on two different hosts or 2 Vagrant / Docker on the same host?
webkruncher
2016-12-02 16:22
@ghaskins no swarm - nothing special
webkruncher
2016-12-02 16:22
Two vagrant / docker on different hosts
garisingh
2016-12-02 16:22
hmm - that might be the issue. You'd be better of trying Docker native on two hosts
ghaskins
2016-12-02 16:22
@webkruncher what I meant was: running "docker-compose up" from two different hosts
garisingh
2016-12-02 16:23
Well - let me start with what is your host OS?
ghaskins
2016-12-02 16:23

2016-12-02 16:24
you certainly can, that would collapse one level of networking
webkruncher
2016-12-02 16:24
k - thx
ghaskins
2016-12-02 16:24
the most straightforward way would be to use something like swarm so you can let docker take care of the SDN overlay

The Query interface is been omitted in the current fabric code. So now query functions will also be logged into the blockchain as transactions?
muralisr
2016-12-05 05:02
@nits7sid since (1) everything is a proposal from client to the peer (to the endorser to be more specific) and (2) proposals are not written to the ledger at the time of endorsement, there is no need to make the distinction between a query and an invoke. The response returned by the proposal will contain the return value (that query used to return) from the chaincode. It is upto the application to determine what should be converted to a transaction to be committed to the ledger
nits7sid
2016-12-05 05:19
oh.. so does that mean if i have just have simple query function in a CC and if i have to make it a transaction then i would have to use PutState() inside the query function? How to determine what should be converted to transaction? Is it from CC level or the SDK will a interface for it?

What is fabric's concurrency model? If two simultaneous transactions invoke the same chaincode, are they forced to run serially or are there locking semantics that would allow the two transactions to run concurrently?

tuand
2016-12-06 19:44
no, but take a look at https://wiki.hyperledger.org/community/fabric-design-docs ... by breaking the peer into endorser/orderer/committer, applications can at least run the endorsement step in parallel

2016-12-07 15:03
@rkr - what are you trying to do? there are currently 2 version of Fabric in play - V1 which is the current master branch and V0.6 which is in the v0.6 branch (and we have also published docker images to dockerhub under the hyperledger organization). If your goal is to start learning chaincode, then for now I would recommend the v0.6 Docker images and following Option 2 or 3 from http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/ . If you want to be on the bleeding edge, things will unfortunately be little tricky with the current master branch (we should have things a bit smoother over the course of the next week or so)
rkr
2016-12-07 15:17

I want to create a fabric application that tracks the provenance of some items. What is a good strategy for doing this? The strategy needs to be scalable, as there will be millions of new items each day, each changing hands a few times a day.
I could generate a unique key for each item. Would that be good?
If I generate a unique key for each item, I would want to compare the change across different world states. Is there a good way to do this?

HL v0.6 does not support tracing historical records of the items. In order to link all the modifications made to an item, you should implement the logic by your chaincode. The query syntax is limited too for many use cases.

Hi all, in the v0.6 protocol spec, under https://github.com/vdods/fabric/blob/v0.6/docs/protocol-spec.md#433-replay-attack-resistance it mentions that it's possible to run fabric with TCerts for transactions (potentially with as few as one TCert per transaction), or with fixed ECerts for transactions. What are the relevant configuration options (in membersrvc, peer, and/or HFC) that are needed to choose between the two?

I want to create multiple assets on Fabric, which I guess is straight forward. But I also want each and every "piece of the asset” to have a unique ID. Is there a better way of doing this than creating 100000 “pieces” of the asset and then sending transactions in batch? Seems like a slow solution where transfer of multiple “pieces” means sending 1 tx for every “pieces”. Would it be possible to do something like a multiTx, where transactions are batched together and signed once?

Question: How does Fabric handle limiting chaincode execution? Like protection from endless loops, deadlocks, ...?
bfuentes
2016-12-09 15:38
@stevenroose this is a good question. No idea if a timeout exists on a transaction call
stevenroose

@stevenroose @bfuentes theres a timeout on call but that’s pretty much it (currently at least). in the v1.0 ’s endorsement model (pre consensus) its less of an issue
stevenroose
2016-12-09 15:48
@muralisr how so? what changes in v1.0 with this regard?
bfuentes
2016-12-09 15:49
@muralisr what happens when 2 calls are done at same time to a chaincode ? Does blocking depends on how is coded the chaincode ? No multi instance of the container ?
muralisr
2016-12-09 15:51
@stevenroose chaincode is executed before consensus - https://jira.hyperledger.org/browse/FAB-37
muralisr
2016-12-09 15:51
@bfuentes currently serial exec so, it would affect
bfuentes
2016-12-09 15:52
@muralisr Thread-safe programming so
muralisr
2016-12-09 15:53
definitely
bfuentes
2016-12-09 15:54
is multi-container a potential good solution for improving performances ?
bfuentes
2016-12-09 15:55
@muralisr today, the container’s name is the hash of the code, but Fabric could start hash-1, hash-2 … etc , in case a high volume of request is done
bfuentes
2016-12-09 15:55
like a clever load balancer start ne containers on demand

Hi all, is there any sort of event-based notification for when a transaction fails with error? For example, using HFC, I get a "complete" event when the transaction completes successfully, but I only get "error" once HFC has timed out and it has guessed that the transaction has failed. My use case is for example attempting to transfer an asset from person X to person Y and that failing say for permissions reasons. The transferring party/parties should be notified not only when the failure happens but the reason for failure as well.
vdods
2016-12-12 01:08
I suppose I could make my own chaincode event, but it seems like notification upon the failure of a transaction is just as important as notification upon success, so it stands to reason this would be a built-in feature.

you can use HTTP or GRPC calls

@bfuentes Thanks. I was just looking into grpc. Am I right in thinking that GRPC is preferred? From a security point of view

NodeSDK is using GRPC, new JavaSDK too. HTTP will be deprecated soon

bfuentes

@pd93 .proto from Fabric, js or java classes are included on SDK. Otherwise you will have to generate the output files yourself

Hi guys I'm working on a new fabric project, and I'm doing my first cloud application - I'm looking for some advice on what consensus options I have with these considerations: 1. Need one network node on an AWS server 2. Several developer machines connecting intermittently on the network
colyerfs
2016-12-12 20:33
can I use noops in this case?
ghaskins

if you only have one node, you probably don't have much of a choice
colyerfs

that's what I figured, pbft can't run without other nodes - the developer machines are only going to be connected intermittently so they'd essentially be NVP's

Hi, I'm now evaluating latest fabric (pre v1.0 or 0.7 ??). I wonder if I can still use "membersrvc" which comes with 0.6 for CA or not. Looks like COP project does not provide Docker image (I heard it's under plan, and heavy development is expected in this month).
keithsmith
2016-12-13 01:14
There is no docker image for COP but it is also very easy to install as follows
keithsmith
2016-12-13 01:14
For now, you'll need one other command as follows
keithsmith
2016-12-13 01:15
mv $GOPATH/bin/cli $GOPATH/bin/cop
keithsmith
2016-12-13 01:15
or if you have $GOROOT set ...
keithsmith
2016-12-13 01:15
mv $GOROOT/bin/cli $GOROOT/bin/cop
keithsmith
2016-12-13 01:17
go 1.6 is the only prereq
keithsmith
2016-12-13 01:23
That said, you can monitor the following change sets for when docker and docker-compose are merged
ibmamnt

@keithsmith Thanks for the info. I'll experiment with COP on native env. for now, and watch those pull requests.

hi all, i have setup 2 peers on different machines, in hyperledger explorer's network information section it shows same IP of both peers i.e. 172.17.0.2. How can i give different IP's to these peers ?
ibmamnt
2016-12-13 05:56
I guess explorer shows the result of /network/peers which happened to be the same ip address of peer host (i.e. Docker network).
ibmamnt
2016-12-13 05:58
And question to this channel. How do I invoke restAPIs in latest fabric ? Is it gone ?? For example, I run "orderer" and "peer" in native machine, then run "curl localhost:7050/chain" gives me "??" message, and orderer shows like:
```2016/12/13 14:50:35 transport: http2Server.HandleStreams received bogus greeting from client: "GET /chain HTTP/1.1\r\nHos"```
ibmamnt
2016-12-13 05:59
And peer only expose "gRPC port". Is there any switch to turn on RESTAPI ?
ankitkamra
2016-12-13 06:41
@ibmamnt its shows the result of rest api. But i need to change the ip address for each peer.
ankitkamra
2016-12-13 06:42
btw according to my knowledge rest api will be deprecate in fabric v1.0
ibmamnt
2016-12-13 07:28
@ankitkamra Thanks for rest api info. As for blockchain explorer, I guess you need to modify explorer code to return host ip/port (iptables or docker-compose ps). Or prepare mapping table in a file, and read it in stead of using /network/peers.
ankitkamra
2016-12-13 07:33
but i want to use rest api's . it should return the actual IP Address of machine through API
ry
2016-12-13 07:49
ankitkamra: I wouldn't build on top of the REST apis, since, as you noted, they're going away
ankitkamra
2016-12-13 07:54
@ry actually i am building an application over fabric-java-sdk and if i register master peer with the sdk, sdk will get information of all renaming peers in the network and will get same address for each peer. now if master peer gets down it will search for docker IP i.e. 172.17.0.1 that does not exist on the network. So i want to know is there any mechanism using which each peer should expose its physical IP.

arner
2016-12-13 20:37
Thanks @ry. So to do manually would mean get the vagrant environment up, checkout the right branch, set environment variables and do ‘make docker’?
arner
2016-12-13 20:37
Does it have any way of knowing which docker image to use as a base of the baseimage?
ry
2016-12-13 20:37
I'm not sure you need vagrant, @ghaskins has done a lot of work to allow for pure docker standup
ghaskins
2016-12-13 20:44
@arner the baseimage can be built by checking out fabric-baseimage.git and running "make docker-local'
ghaskins
2016-12-13 20:45
and the main tree links to that via fabric.git/.baseimage-release
ghaskins
2016-12-13 20:55
from there: "make native" will generate local binaries, and "make docker" will generate the other images as a function of baseimage
ghaskins
2016-12-13 20:56
you may or may not need vagrant to complete the second part, depending on your host environment
ghaskins
2016-12-13 20:56
but if you are targetting Pi, best to try to not need it
ghaskins
2016-12-13 20:56
I can guide you on the necessary prerequisites for the host
ghaskins
2016-12-13 20:57
we don't support cross-compiling (yet), but we do support multi-arch compilation if you have a suitable host for the $arch in question
ghaskins
2016-12-13 20:58
so, this means you'll probably need to do a lot of this on the Pi iteself, unless you have another suitable/compatible ARM platform
arner
2016-12-13 21:00
Ha you keep answering my questions before I finished typing. Ok I will try to do this when I have access to a Pi again. Do I need things like RocksDB on the host or is it just basic build stuff that needs to be there? Would prefer not to use vagrant indeed.
ghaskins
2016-12-13 21:00
master no longer requires librocksdb
ghaskins
2016-12-13 21:00
if you want to build the v0.6 branch, that is a different question
arner
2016-12-13 21:01
Yes that would be my goal for now. Looks like an interesting weekend project coming up :wink:
ghaskins
2016-12-13 21:01
basically you just need a unix platform with make, git, golang v1.6 or higher, and docker
ghaskins
2016-12-13 21:01
(docker-compose, if you want to run the unit-tests too)
arner
2016-12-13 21:01
Ok great. And librocksdb
ghaskins
2016-12-13 21:01
yes, though note that the build proceedure for v0.6 is slightly different
ghaskins
2016-12-13 21:02
1) the baseimage is part of fabric.git (see images/base) in v0.6
ghaskins
2016-12-13 21:02
2) you still need librocksdb (as you have noted)
ghaskins
2016-12-13 21:02
3) the linkage from fabric->baseimage is in fabric.git/images/base/release
ghaskins
2016-12-13 21:02
I cant think of any other major differences
ghaskins
2016-12-13 21:03
but ill ping back if they occur to me
arner
2016-12-13 21:03
Thanks a lot!
ghaskins
2016-12-13 21:03
unforunately in v0.6 youll probably need a lot more substrate, like protoc, node, etc
ghaskins
2016-12-13 21:03
most of that is no longer required on the host in master, but that only went in recently
ghaskins
2016-12-13 21:03
i have to step away, bbiab
arner
2016-12-13 21:18
@ghaskins I can find `make docker` in the images/base/Makefile. Are the four lines in https://github.com/hyperledger/fabric/blob/v0.6/images/app/Dockerfile.in actually all you need to copy in the compiled memberservice and peer respectively to create those images? Or am I missing the script that creates those?
arner
2016-12-13 21:21
Ah right, `make images` from the root should do the trick.

(the rationale was that "images" was too vague, so now there is "make native" for native binaries and "make docker" for docker images

note that there are rules to target a specific image too: e.g. "make peer-image" or "make peer-image-clean"

Does Fabric have a built-in method like Get() that can pull/fetch data from the network?
vdods
2016-12-14 21:11
@colyerfs Can you give a little more context? The shim.ChaincodeStubInterface interface provides a way for golang-based chaincode to get/set the ledger state. If you're thinking about e.g. a web app retrieving data from the ledger, then one could use the HFC module (fabric-sdk-node) to submit a query request to a peer for the relevant data
colyerfs
2016-12-14 21:23
@vdods sorry for the vague question, typed it out quick... yes I was referring to a web app retrieving data from the ledger
colyerfs
2016-12-14 21:24
so I'll take a look at the HFC module
colyerfs
2016-12-14 21:25
how would I go about querying data? is there a specific method in HFC?
vdods
2016-12-14 21:26
@colyerfs There's no generic built-in way, but you can easily define your own query method in chaincode. Which version of fabric are you working with?
colyerfs
2016-12-14 21:28
@vdods gotcha - v0.6, so I'd define the query in a chaincode event?
vdods
2016-12-14 21:30
@colyerfs Not an event, but chaincode yes. Take a look at chaincode_example02.go for a really simple example, and take a look at fabric/sdk/node/test/unit/chain-tests.js for how to use HFC to invoke/query/etc
vdods
2016-12-14 21:32
Running the HFC unit tests as is is a little tricky, but if you want a simpler way to do it, I've made a fork of fabric v0.6 which dockerizes the HFC unit tests. https://github.com/vdods/fabric/blob/dockerize-unit-tests/sdk/node/dockerized-unit-tests-readme.md

BlueMix offers a sample network in v0,5 and v0.6, so people can get some experience with it and get to know how it works. I would expect different offerings for v1.0, since the architecture is changing.

Quick question, "submitting peer" has been removed from latest v1.0 spec. Is this correct ? My understanding "submitting client" directly connect to endorser (endorsing peer).
janmike
2016-12-19 08:26
Once 1.0 is rolled out March 2017 as per the schedule shared, will we get more than 4 peers within the network?
bfuentes
2016-12-19 09:18
@janmike you are talking about Bluemix Blockchain as a Service
bfuentes
2016-12-19 09:18
today, you can have more than 4 peers if you run the network yourself
bfuentes
2016-12-19 09:19
I guess, Bluemix service will evolve for next release to enable dynamic peer number
garisingh
2016-12-19 09:24
@janmike - the purpose of the Bluemix service(s) was to provide a "sandbox" environment to demonstrate Fabric capabilities. And while there is/was no theoretical limit to the number of peers in a Fabric v0.6-based network, you needed to define the number up front. So we picked 4 in Bluemix as it fits the "3f+1" BFT model so that we could show all of the features of Fabric (e.g. you can stop 1 peer and the network still moves forward, you can stop 2 peers and the network will halt, you can restart a peer, etc).
Of course V1 offers the ability for peers to be dynamically added to Fabric networks so that makes things a lot easier in terms of the types of services which can be delivered
janmike

I was about to return here and state the same point. Thank you both for the response, I did my reading again and mis interpreted. Also read the PBFT protocols
janmike
2016-12-19 09:27
Thanks @bfuentes and @garisingh
janmike
2016-12-19 09:28
I'm now assessing as to the cost of running fabric on my own - or look to BlueMix for that altogether.
garisingh
2016-12-19 09:29
sounds good @janmike - feel free to ping me directly if you have any specific questions about the Bluemix services (my team actually owns building and delivering those Bluemix services)
janmike
2016-12-19 09:29
My worry is the cost for a 4-node training and trial landscape -- is already at 10k. I'm hopeful someone releases a proper BaaS as that of Azure's Ethereum
janmike
2016-12-19 09:30
Fantastic @garisingh -- im building up a business case to make a decision on whether to invest effort on Fabric or Ethereum.
janmike
2016-12-19 09:31
I'm leaning towards Fabric over Ethereum to be honest as our customers are mostly Enterprise

Anyone know why I'm getting this error? `cannot use con (type *"http://github.com/pd93/fabric-sdk-go/vendor/google.golang.org/grpc".ClientConn) as type *"http://github.com/hyperledger/fabric/vendor/google.golang.org/grpc".ClientConn in argument to protos.NewDevopsClient`
bfuentes
2016-12-19 12:42
i think , you should import the type expected from this package path “http://github.com/hyperledger/fabric/vendor/google.golang.org/grpc"
pd93
2016-12-19 12:45
@bfuentes if I use the package that is vendored with Fabric, I get this:
`imports http://github.com/hyperledger/fabric/vendor/google.golang.org/grpc: use of vendored package not allowed` :confused:
garisingh
2016-12-19 12:55
@pd93 - what exactly are you trying to do? I assume build a Go-based SDK for Fabric v0.6?
garisingh
2016-12-19 12:55
looks like you are vendoring both fabric and grpc-go in your project?
pd93
2016-12-19 12:58
@pd93 uploaded a file: https://hyperledgerproject.slack.com/files/pd93/F3H63U63Y/imports.go and commented: @garisingh essentially, yes. It's just a lightweight wrapper for the GRPC calls. My imports are above
pd93
2016-12-19 12:58
There is no `/vendor` folder in my project
garisingh
2016-12-19 13:18
```
cannot use con (type *"http://github.com/pd93/fabric-sdk-go/vendor/google.golang.org/grpc".ClientConn) as type *"http://github.com/hyperledger/fabric/vendor/google.golang.org/grpc".ClientConn in argument to protos.NewDevopsClient
```
can you post the code that was generating that error?
And is it safe to assume that you have the Fabric v0.6 source directly in your GOPATH (you said it was not vendored)
pd93
2016-12-19 13:22
@pd93 uploaded a file: https://hyperledgerproject.slack.com/files/pd93/F3FQE4RUY/-.go and commented: In this snippet, it is line 11 causing the issue. I'm assuming it doesn't like the type that the GRPC package is returning.

Hello,
I would like an example of a docker-compose.yml file or use swarm to deploy multiple containers in several machines connected with swarm.
For example 3 containers vp0 vp1 vp2.
garisingh
2016-12-19 14:10
@pd93 - so I got this to work by "vendoring" both the grpc and fabric packages within my project
pd93
2016-12-19 14:13
@garisingh Great, thanks!
When you say vendor, I assume you mean using something like `govend` to add the packages to a `/vendor` folder?
garisingh
2016-12-19 14:15
yeah - I used go vendor
Basically, within the root folder of my project:
`govendor init`
`govendor add +external`
pd93
2016-12-19 14:26
@garisingh I've run those two commands, but it only vendored parts of fabric (protos and core/util) and I'm now getting `undefined grpc in grpc.Dial`. Is this a separate issue?
yacovm
2016-12-19 14:27
Did you import it?
garisingh
2016-12-19 14:28
```
import(
pb "http://github.com/hyperledger/fabric/protos"
grpc "http://google.golang.org/grpc"
"fmt"
)
```
garisingh
2016-12-19 14:29

For now I just want feedback on how can deploy on multiple machines
ahmedelhajji
2016-12-20 15:20
I tryed with docker-machine, but I think it is necessary to go through docker swarm because it is the solution docker distribute
name63
2016-12-20 15:22
mostly it depends on the scale of your docker network and the amount of docker containers you are managing
name63
2016-12-20 15:24
since you have just 4 of them, you can bootstrap two docker-engine hosts and split your single docker-compose into two files: https://alexanderzeitler.com/articles/docker-machine-and-docker-compose-developer-workflows/
garisingh
2016-12-20 15:25
@ahmedelhajji - the only real "trick" here is getting the networking correct
ghaskins
2016-12-20 15:33
@ahmedelhajji: if you want to orchestrate a cluster of peers from one place/config, you want to use something like swarm or kubernetes
ghaskins
2016-12-20 15:33
If you don't mind managing the networking yourself, there are a ton of options
ghaskins
2016-12-20 15:36
Like @garisingh said, the main thing is managing the network config: platforms like swarm/kubernetes will do this for you, or you can manage it manually if you know what you are doing
ghaskins
2016-12-20 15:36
For 4 peers, either methodology will work
ahmedelhajji
2016-12-20 15:42
@ghaskins yes for now im using swarm but when I build my docker-compose.yml file and I execute docker-compose bundle I get file "mycc.deb" after that I execute the deploy docker deploy mycc I have this error "only supported with experimental daemon" . So i looked for a solution and it seems that "experimental" flag must be set to true... Unfortunately mine is stuck to false. Am I doing something wrong or is it a good hint to follow?
garisingh
2016-12-20 15:51
@ahmedelhajji - prior to Docker 1.13, experimental features were not built-in to the standard daemon distribution(s) - https://experimental.docker.com/builds/

@ahmedelhajji sorry, I don't have operational experience with swarm, I just understand its function architecturally
ghaskins
2016-12-20 16:22
fwiw, I build our prototypes on openshift origin, its quite nice
ahmedelhajji
2016-12-20 16:32
oh ok, thank you for your help i will take a look at openshift origin
ghaskins
2016-12-20 17:21
@ahmedelhajji to be clear: kubernetes/openshift will be significantly more effort to learn/stand-up compared to docker-compose (and, IIUC, swarm)
ghaskins
2016-12-20 17:22
its more suited to a production deployment
ghaskins
2016-12-20 17:22
if you just want to hack around, theres probably much easier paths

Hi all, it seems that Fabric starts dropping connections if I try and make more than approximately 200/sec. Is this a Virtualbox limit with the devenv or is there a bottleneck
garisingh
2016-12-21 15:13
@benlewis - what do you mean by "dropping" connections? and which version are you using?
benlewis
2016-12-21 15:14
@garisingh I'm using v0.6 in the dev environment, after a certain number of connections, I'm getting an error message that the connection was refused
benlewis
2016-12-21 15:15
If I retry them a few times, they eventually go through. However, I have a suspicion it is being caused by VirtualBox
garisingh
2016-12-21 15:23
are you doing it all within VirtualBox or connecting from outside of VirtualBox? You might be running into a file descriptor limit in the latter. I think we up the number of descriptors within VirtualBox. Of course I would not do any stress testing with VirtualBox myself - I'd minimally move to using a pure Docker env
benlewis
2016-12-21 15:26
I'm connecting from outside of virtualbox
benlewis
2016-12-21 15:37
@garisingh It's only from outside from virtualbox it occurs, running the same client inside the devenv gives no errors
garisingh
2016-12-21 15:37
what's your host system?
benlewis
2016-12-21 15:37

i7-3620qm (4 core, 8 thread) with 16gb of RAM & SSD
garisingh
2016-12-21 15:46
there used to be a concurrent connection limit on Windows systems. You might be hitting that
benlewis
2016-12-21 15:46
In theory, they removed it with Vista but it seems to be a network-based issue, so I'll migrate to running in Docker I think

When running Fabric in docker, is it necessary to forward ports?
ashishkel
2016-12-22 12:58
@benlewis In my knowledge, if you are running only one node, and if your host OS considers the port u are using inside docker as within user range, then it's not needed to forward the ports at all.
ashishkel
2016-12-22 13:02
But if you are running multiple docker nodes, then all the nodes listening on the same set of ports within the same host OS is not allowed. And in multi-node situation, you have to forward the ports to unique host ports for reliable operation.

Channel, I have trouble with using proto.Unmarshal in my chaincode. I try to unmarshal a shim.Row from bytes. The problem is that this works when I place this function inside the fabric, for example vendor/github.com/hyperledger/fabric/core/chaincode/shim/chaincode.go. However, when I try to proto.Unmarshal outside the fabric it does not properly unmarshal the bytes, but neither does it give an error.
Has anyone encountered this problem before or know why the proto.Unmarshal is not usable outside the fabric?

using chaincode_example02 with REST APIs. Anyone know why the query command fails every time? The deploy and invoke commands work just fine.

@mike_dircz Hi Mike, the deploy and invoke commands are asynchronous....they just return a "transaction id" but then if something goes wrong during the deploy or invoke, they won't tell you about it (at least not via the REST API...with the SDKs you can subscribe to events)..... on the other hand, query's are synchronous, so if something goes wrong you find out about it right away. I suspect that your deploy may have failed.
mike_dircz
2016-12-22 20:21
@silliman the results from the Deploy:
{
"jsonrpc": "2.0",
"result": {
"status": "OK",
"message": "mycc"
},
"id": 1
}
silliman
2016-12-22 20:24
@mike_dircz right, but, unfortunately, all that that's telling you is "I've submitted the deployment request OK".... it is not telling you whether the deployment completed successfully
mike_dircz
2016-12-22 20:25
hi @silliman, debugging tips?
silliman
2016-12-22 20:25
@mike_dircz IIRC, you are running with the docker images, are you running in chaincodedev mode?
ghaskins
2016-12-22 20:26
@mike_dircz simplest thing is to look at the peer logs
mike_dircz
2016-12-22 20:26
@silliman yes chaincodedev mode
silliman
2016-12-22 20:26
@mike_dircz yes, in your peer log you should see a message like this: ```20:12:14.350 [rest] ProcessChaincode -> INFO 01a REST processing chaincode request...
20:12:14.350 [rest] processChaincodeDeploy -> INFO 01b REST deploying chaincode...
20:12:14.351 [rest] processChaincodeDeploy -> INFO 01c Successfully deployed chainCode: mycc
20:12:14.351 [rest] ProcessChaincode -> INFO 01d REST successfully deploy chaincode: {"jsonrpc":"2.0","result":{"status":"OK","message":"mycc"},"id":1}
```
silliman
2016-12-22 20:27
hmm that does look a lot like what you posted in though, so there may be more to it than that
silliman
2016-12-22 20:29
@mike_dircz also, in the log for the chaincode, you should see several messages that start out with this at about the same time you submit the deploy... ```20:12:15.355 [shim] DEBU : [mycc]Received message INIT from shim
20:12:15.355 [shim] DEBU : [mycc]Handling ChaincodeMessage of type: INIT(state:established)
20:12:15.355 [shim] DEBU : Entered state init
20:12:15.355 [shim] DEBU : [mycc]Received INIT, initializing chaincode
Aval = 100, Bval = 200
```
silliman
2016-12-22 20:31
@mike_dircz my last code snippet is from the log output from the command to start chaincode_example02, not to be confused with the log output from peer which is what my first code snippet is from
silliman
2016-12-22 20:34
@mike_dircz One other thing seems a little odd to me... in the original output you posted a little while ago, there's this....
Error starting Simple chaincode: Error handling message: [80a15e2a-b59a-4501-8529-b495b472589c]Chaincode handler FSM cannot handle message (RANGE_QUERY_STATE) with payload size (10) while in state: readyMikes-MacBook-Pro-3:*chaincode_exampleE_PEER_ADDRESS=0.0.0.0:7051* ./chaincode_example02
maybe it's a cut-and-paste error, or maybe some bad output formatting from the fabric code, but see how chaincode_exampleE_PEER_ADDRESS=.. seems to have some squashing or truncation going on (i.e., why does is say E_PEER_ADDRESS and not CORE_PEER_ADDRESS) ... now that might be a red herring but it jumps out at me
silliman
2016-12-22 20:44
@mike_dircz something to verify- did you start the chaincode_example02 as a separate process as you must do in *chaincodedev* mode. As an experiment, I purposely skipped that required step, and then I went and submitted the deploy via the REST API, and I received the same result you posted ```{"jsonrpc":"2.0","result":{"status":"OK","message":"mycc"},"id":1}``` but, within the peer log this is an indication that something went wrong: ```20:40:45.789 [chaincode] Launch -> ERRO 01e sending init failed(handler not found for chaincode mycc)```
silliman
2016-12-22 20:47
@mike_dircz similarly, if I now POST an invoke while in this situation, my immediate response looks like everything is okay, i.e. ```{
"jsonrpc": "2.0",
"result": {
"status": "OK",
"message": "ca050000-db27-4211-b144-078e10045466"
},
"id": 3
}``` but if I look in my peer logs I see the real truth: ```20:45:43.366 [chaincode] Launch -> ERRO 024 You are attempting to perform an action other than Deploy on Chaincode that is not ready and you are in developer mode. Did you forget to Deploy your chaincode?
```
silliman
2016-12-22 20:50
@mike_dircz sadly, however, it's probably you have something else going on, as when I then submit a query, my error message is different from yours, I get this: ```{
"jsonrpc": "2.0",
"error": {
"code": -32003,
"message": "Query failure",
"data": "Error when querying chaincode: Error:Failed to launch chaincode spec(Could not get deployment transaction for mycc - LedgerError - ResourceNotFound: ledger: resource not found)"
},
"id": 5
}```
mike_dircz
2016-12-22 21:00
hi @silliman I will chip away at each of those log files and see what it turns up. My peer logs don't contain any useful informations, so maybe I didn't turn on the right level of logging. Example logs entries:
vp0_1 | 21:00:05.684 [peer] ensureConnected -> DEBU 3a2 Connected to: []
vp0_1 | 21:00:05.684 [peer] ensureConnected -> DEBU 3a3 Discovery knows about: []

garisingh

@benlewis - the problem is that there is no latest tag for fabric-baseimage - so you either need to pull down the image using the proper platform tag or you can simply retag the fabric-peer image : `docker tag hyperledger/fabric-peer:latest hyperledger/fabric-baseimage:latest`

General question: If I had a business case that required an object, say a Car, to be stored on the blockchain and access to certain properties of that car restricted to certain roles, can I do that in 0.6 and is there an example that demonstrates this feature? For example, the car has “Make, Model, and Year” but only the manufacturer and owner can see all three, an auctioneer can only see Make, and Model.

2016-12-24 04:58
A few questions about V1.
1. Can we still invoke a chaincode from another chaincode?
2. Can we simulate a PBFT network equivalent to V0.6? For example, when I want to set up a network which allows 1 failing endorser out of 4 total endorsers, how can I enforce that policy? Should I just select some options for the orderer or do I have to develop a customized Node SDK client?

modifying / creating your own users should be pretty straightforward. I guess you'll need to decide whether or not you want to add simply add to the existing users (which can be done via environment variable or via the NodeSDK after the fact) or you can modify the yaml itself and then build the image using the appropriate make directive (I forget the exact name but it's in the makefile)
harsha544
2016-12-27 16:44
@garisingh how do we add new users in V1.0 is it via fabric-cop, if so how can we do that?
jonathanlevi
2016-12-27 18:31
Yes, it’s `make membersrvc` (in v0.5, v0.6)
jonathanlevi

@harsha544: I have forwarded your question to the #fabric-cop channel.
jonathanlevi
2016-12-27 18:34
(In a line, the simplest is to use the fabric-sdk - the NodeJS version is the most “feature-rich” SDK in Fabric to date… and it allows you to dynamically add users - there is a Register/Enroll step that you can use)
shrike
2016-12-27 23:53

@ashishkel - the architecture is not backwards compatible with v0.6 (although you'll only need to make a few minor changes to chaincode developed in v0.6 for it to work with v1.0)
garisingh
2016-12-29 15:48
v0.7 is actually the v1.0 architecture but basically the master branch will continue to evolve to the final v1.0 architecture. most of the interfaces are pretty solid right now
ashishkel
2016-12-29 16:49
@garisingh Okay, That's okay, minor changes are always okay.

Hi,
I saw sample on youtube relates with Hyperledger for art auction.
I want to deploy to my local machine.Please provide me a proper installation guide for it.
I tried github sample but i am much confused related what additional softwares like vagrant,node .js installation for ubuntu.
please took a king consideration.

With the events SDK, would I be correct in thinking it just publishes to an event stream when called from chaincode?
muralisr
2016-12-30 14:34
@benlewis yes, events is sent on a grpc stream @pmullaney will have more details on the SDK implementation for events
benlewis
2016-12-30 14:35
@muralisr thanks
muralisr
2016-12-30 14:35
sure thing
benlewis
2016-12-30 14:38
@muralisr Do you know if each validating peer hosts the grpc event stream?
muralisr
2016-12-30 14:41
@benlewis yes, each peer would. are you talking about the master or 0.6/0.7 fabric ?
benlewis
2016-12-30 14:41
I'm using the v0.6 at the moment
muralisr
2016-12-30 14:42
there is no events support in the SDK - I thought - on 0.6/0.7 .
muralisr
2016-12-30 14:42
or perhaps I am wrong ?
benlewis
2016-12-30 14:43
It's documented under the examples on the v0.6 branch
muralisr
2016-12-30 14:43
ok
benlewis
2016-12-30 14:44
Thanks for your help though, it should mean I can make use of the block listener
muralisr
2016-12-30 14:44
its been a while since I used 0.6. Let me double check
muralisr
2016-12-30 14:45
support is there in 0.6 SDK (how quickly one forgets!) … sorry about that @benlewis
benlewis
2016-12-30 14:46
don't worry, I know 0.6 is old by now but I'm aiming for stable for prototypes and demos. Thank you though for your help
muralisr
2016-12-30 14:47
yw
ghaskins
2016-12-30 14:52
@muralisr @benlewis I can confirm that v0.6 SDK supports at least basic events (e.g. deploy/invoke completion)
ghaskins
2016-12-30 14:52
not sure about chaincode events
ghaskins
2016-12-30 14:53
I was using nodesdk v0.6.5 and fabric v0.6.1-preview and they worked fine
muralisr
2016-12-30 14:53
thanks @ghaskins … I think I was conflating with chaincode events
ghaskins
2016-12-30 14:54
@muralisr thats understandable...those are the more interesting ones :wink:
muralisr
2016-12-30 14:54
indeed :slightly_smiling_face:
ghaskins
2016-12-30 14:54
though actually having the txn complete events is critical too, so it was a welcome addition
benlewis
2016-12-30 14:55
Chaincode events are the ones I'm looking for ideally but I can always build v1.0 if needed
ghaskins
2016-12-30 14:55
@benlewis best to ask @pmullaney...it could very well have chaincode events in v0.6, I am not sure
benlewis
2016-12-30 14:56
It at least compiles, which is a good sign

Hi All. How can I query multiple items? For example get a list of all `users` that belong to bank B? This means all user that have `bank` set to *B* ?
muralisr
2016-12-30 15:14
@rafael.turk given there’s no rich query capability like SQL, you have to either get the list and iterate or maintain a mapping from bank to users
muralisr
2016-12-30 15:15
I’d check in fabric-ledger or fabric-ledger-dev for plans for query capabilities (especially with couchdb support) in 1.0
benlewis

I'm trying to make the peer on 16.04 and I get a path error for rocksdb.c

2016-12-30 15:28
Ubuntu*
rafael.turk
2016-12-30 15:31
@muralisr so what’s the fastest/more efficient way to get a list?
rafael.turk
2016-12-30 15:33
Meaning.. in a array or even array of ids..
muralisr
2016-12-30 15:37
it depends so much on the use case (will there be more updates or just reads, how many items in the bank->users map, etc)
ghaskins
2016-12-30 15:55
@benlewis I assume you are trying to build v0.6?
benlewis
2016-12-30 15:55
@ghaskins Yes I am
ghaskins
2016-12-30 15:55
the only supported method of building in v0.6 is via vagrant
ghaskins
2016-12-30 15:56
cd devenv && vagrant up
ghaskins
2016-12-30 15:56
that would get you an environment that has all the prerequisites for building
ghaskins
2016-12-30 15:56
that said, if you want to, you can replicate the setup on your own
benlewis
2016-12-30 15:57
ah okay, thanks
ghaskins
2016-12-30 15:57
in v0.6, theres two parts: the baseimage and devenv
ghaskins
2016-12-30 15:57
baseimage scripts are in ./images/base (IIRC)
ghaskins
2016-12-30 15:57
and devenv is in ./devenv
benlewis
2016-12-30 15:58
I do have the vagrant devenv set up, I was just trying to be lazy with testing and it didn't work
ghaskins
2016-12-30 15:58
in there, you would see the recipe for building librocksdb.so that you are missing
ghaskins
2016-12-30 15:58
ok, cool, thats the easiest path
ghaskins
2016-12-30 15:58
in master/mainline, the requirements are greatly relaxed such that you can build from most places
ghaskins
2016-12-30 15:59
but v0.6 still has the old setup
benlewis
2016-12-30 15:59
That'll be where I was getting confused, I was assuming the references to building locally would also count for v0.6 which they don't
ghaskins
2016-12-30 16:01
ah, gotcha

@garisingh commented on @karnn’s file https://hyperledgerproject.slack.com/files/karnn/F3L3B2K7V/problems_building_fabric.txt: looks like you have some type of network / DNS error. Within Vagrant, what happens if you do `ping http://index.docker.io`?
garisingh
2016-12-31 10:25
what about on your host OS outside of Vagrant?
karnn

karnn
2016-12-31 10:28
@garisingh is this a problem with vagrant's port forwarding or with the dns server i'm connected to?
garisingh
2016-12-31 10:30
hmm - well looks like your host is connecting just fine so that's good news. Unfortunately I am not an expert on Vagrant so not sure why DNS resolution is not working correctly
karnn
2016-12-31 10:33
@garisingh should i just destroy and up again?
karnn
2016-12-31 10:34
@garisingh also quick question, the repo i clone from gerrit is the latest build right? the 0.6 release is something i need to clone manually right/
garisingh
2016-12-31 10:35
I'd go with the destroy approach. And yes - by default you would clone the master branch which is the current working branch for the next release(s)
garisingh
2016-12-31 10:36
BTW - if you are working off the master branch, you don't actually need to use Vagrant anymore. You just need to have Docker installed locally on your host system
garisingh
2016-12-31 10:37
For example, I use OSX and I run everything within OSX and don't use Vagrant at all
karnn
2016-12-31 10:39
@garisingh i use rhel7.2. so i need to have docker and follow the same docs?
garisingh
2016-12-31 10:42
right
karnn
2016-12-31 11:37
@garisingh quick question. is there a problem if i build "sudo make dist-clean all" in in the '/src/github.com/hyperledger/fabric' folder. or should i make a new docker group and add user to that group so that i can connect to docker.
karnn
2016-12-31 11:54
@garisingh nvm, i'll just make a docker group to be safe
garisingh
2016-12-31 12:18
I go with the docker group

karthik
2017-01-03 08:02
When I try to deploy the chaincode using "peer chaincode deploy -n mycc -c '{"Args": ["init", "a","100", "b", "200"]}'"
karthik
2017-01-03 08:02
I am getting a "peer command not found" error.
ashishkel
2017-01-03 08:22
@karthik If you are using docker images, then you have to login to the bash shell of running docker instance and then execute those commands.
karthik
2017-01-03 08:29
@ashishkel So the chaincode registration step also needs to be inside docker right?
ashishkel
2017-01-03 08:30
The peer executable is available only inside the docker's bash shell. So yes.
ashishkel
2017-01-03 08:33
@karthik You have to build the Chaincode executable inside the docker I guess. Because the go environment, outside the docker, i.e, present in the host OS and the one present inside the docker might be different.
karthik
2017-01-03 08:34
@ashishkel Thanks for the help. I will try this and get back to you.

is the path absolute, or is it relative to something?

@rahulhegde remote chaincode dowload using ` -p https://github.com/rahulhegde/learn-chaincode/start` is incompatible with `—peer-chaincodedev` mode
muralisr
2017-01-04 15:34
`—peer-chaincodedev` is meant for local dev/testing for faster turnaround with chaincode development
muralisr
2017-01-04 15:35
with it a developer starts the chaincode directly (instead of having the chaincode start it)
muralisr
2017-01-04 15:35
you don’t have to deploy the chaincode at all with -p option

thojest
2017-01-04 16:10
seems that the 3 days of despair are paying out now because i dont have to use vagrant
benlewis
2017-01-04 16:11
I tried doing that and wasn't making progress. I can get everything else running with no issues in Vagrant. My chaincode is now working and ready, it just needs a front-end
benlewis
2017-01-04 16:11
how did you install the hfc module?
thojest
2017-01-04 16:11
yeah same here. very simple chaincode ready but want to develop a front end

2017-01-04 16:12
just using `npm install hfc` i think

@rahulhegde here are the instructions to run `—peer-chaincodedev` mode in 1.0
muralisr
2017-01-04 16:25
```Will use the CLI/Vagrant env for these steps to run in --peer-chaincodedev mode in 1.0
Vagrant window 1 - build peer
make peer
Vagrant window 2 - start orderer
cd orderer
go build
./orderer
Vagrant window 2 - start peer in dev mode
cd peer
peer node start --peer-chaincodedev
Vagrant window 3 - start chaincode example02 in dev mode
cd examples/chaincode/go/chaincode_example02
go build
CORE_PEER_ADDRESS=127.0.0.1:7051 CORE_CHAINCODE_ID_NAME=mycc ./chaincode_example02
Vagrant window 4 - initialize the chaincode using the "deploy" command
cd peer
CORE_CHAINCODE_MODE=dev peer chaincode deploy -n mycc -c '{"Args":["init","a","100","b","200"]}'
CORE_CHAINCODE_MODE=dev is needed in 1.0 with chaincode deploy. Unlike 0.6/0.7, 1.0 builds the
chaincode in the deploy command. CORE_CHAINCODE_MODE=dev is needed to tell the deploy command
not to skip build related activities
#wait for about 10seconds
#kill Ctrl-C chaincode_example02 and start chaincode_example02 again in Vagrant window 3.
#This is needed - for now - as the fabric deregisters the chaincode after deploy
Vagrant window 3 - restart chaincode
Ctrl-C running chaincode
CORE_PEER_ADDRESS=127.0.0.1:7051 CORE_CHAINCODE_ID_NAME=mycc ./chaincode_example02
#now you can send invokes and queries as usual from window 4
Vagrant window 4 - send an invoke
cd peer
CORE_CHAINCODE_MODE=dev peer chaincode invoke -n mycc -c '{"Args":["invoke","a","b","10"]}’```

nickmelis
2017-01-04 16:28
is it possible to use the Java SDK to listen for events?
thojest
2017-01-04 16:28
the peer node tells me `grpc: Server.Serve failed to create ServerTransport: connection error: desc=....`
benlewis
2017-01-04 16:31
@nickmelis I believe it just sends events over gRPC so you could write a client to listen for them anyway
benlewis
2017-01-04 16:31
@thojest Are you connecting to the correct address for the core peer?
benlewis
2017-01-04 16:32
Btw, I fixed the issues running node, upgrading and fixing the path fixed it
thojest
2017-01-04 16:33
@benlewis nice to hear
nickmelis
2017-01-04 16:41
What does the Java SDK support at the moment? Members creation? Chaincode creation/invocation?
benlewis
2017-01-04 16:42
https://github.com/hyperledger/fabric-sdk-java this gives some indication, but I've personally stuck to using golang and node as they're the best documented
thojest
2017-01-04 16:43
@benlewis @nickmelis thats exactly the reason why i prefered go over java. just because of documentation although i have never written a piece of golang
benlewis
2017-01-04 16:45
I've found golang is fairly straightforward, and with documentation and Google, I've not had too many difficulties
thojest
2017-01-04 16:46
@benlewis same here, especially together with the chaincode examples
cbf
2017-01-04 16:46
@thojest which version are you running? v0.6 images or from master?
thojest
2017-01-04 16:46
v0.6
cbf
2017-01-04 16:47
suggest you use the v0.6 documentation http://hyperledger-fabric.readthedocs.io/en/v0.6/ that should match the published images, where the 'latest' docs may be updated for some of the recent changes to the code that might be incompatible
nickmelis
2017-01-04 16:49
@thojest yes in fact I can see very little documentation on the Java SDK. But is it actively being developed?
thojest
2017-01-04 16:50
@nickmelis dunno you have to ask that to someone whos contributing :smile:
thojest
2017-01-04 16:50
im just getting started
benlewis
2017-01-04 16:51
@nickmelis As far as I'm aware, there is a Java and Python SDK in active development, but my best guess is that Golang gets the most attention as the rest of the code is also in Go. The NodeSDK was the first and is the most prominent one
benlewis
2017-01-04 16:51
You could also use the REST API but they've removed that in v1.0 as far as I know
thojest
2017-01-04 16:51
@cbf im basically following this instruction but i built v0.6 myself on baremetal ubuntu so maybe there is some configuration problem because i did it myself
nickmelis
2017-01-04 16:52
so what’s the best way to interact with the fabric from Java?
benlewis
2017-01-04 16:53
Are you using v0.6 or v1.0?
nickmelis
2017-01-04 16:53
0.6, but it doesn’t really make sense to start using REST API if they’re going to be removed in 1.0
cbf
2017-01-04 16:54
@thojest I see
cbf
2017-01-04 16:54
is there a reason that you need to run this bare metal?
cbf
2017-01-04 16:55
@nickmelis the Java SDK can work with v0.6 though I think that if you want to explore with java chaincode that you may need a patch
cbf
2017-01-04 16:57
@thojest I shouldn't think there would be a problem building it yourself
cbf
2017-01-04 16:57
@garisingh has built it natively on ubuntu (and basically all the platforms) so you might ping him if there are any gotchas
nickmelis
2017-01-04 17:00
@cbf is it preferrable to work with Java SDK and v1.0? Is that what you’re saying?
nickmelis
2017-01-04 17:00
I looked at HyperLedger a few months ago and am not really up to date with the latest developments
thojest
2017-01-04 17:03
@cbf somebody told me that avoiding vagrant offers some benefits. and indeed until now everything worked very nicely
thojest
2017-01-04 17:05
@cbf @garisingh so the complete error message i get is`2017/01/04 17:59:54 transport: http2Server.HandleStreams failed to receive the preface from client: read tcp 127.0.0.1:7051->127.0.0.1:55672: read: connection reset by peer

@thojest if you are seeing the problem logged in FAB-321 (number of arguments does not match what the chaincode expected), you should update hfc to v0.6.1 or later (might as well get the latest v0.6.5) and try again
jzhang
2017-01-04 19:19
also on your question above regarding java SDK, it’s being worked on by @pvishnum @rickr @maltaf and is targeting a March “release" along with the node.js SDK for fabric v1.0
jzhang
2017-01-04 19:22
@nickmelis JSON RPC APIs (some call it REST) are removed from the Peer nodes. but the node SDK team is working on adding it to the SDK. I hope the Java SDK will also have that. https://jira.hyperledger.org/browse/FAB-156

@jzhang does it mean I may end up not having the REST API anymore and not having any way to interact with the chaincode in the Java SDK too?
jzhang
2017-01-04 21:35
@nickmelis with java sdk you can always use its APIs to interact with the chaincode (which communicates via grpc under the cover), and if the Java SDK team do not deliver the JSON RPC wrapper, then you can always use the node.js SDK to achieve that. delivering the JSON RPC wrapper is a high priority item for the node.js SDK team and @anya has been working on that

ok I see…so I still have a way to interact with the chaincode using Java SDK. Has it been tested with v1.0 too?
nickmelis
2017-01-04 21:36
also I guess if I use the node SDK it will expose the rest APIs which I can then use from my Java app, right?

Is there any example of docker compose file which has
1. COP docker image with either MySQL or PostgreSQL setup
2. Endorser (peer) and Orders (orderer) with Kafka setup, and Endorser uses couchdb connection
So far, I have found these:
> https://github.com/hyperledger/fabric-sdk-node/blob/master/test/fixtures/docker-compose-marbles.yml
> https://github.com/hyperledger/fabric-cop/blob/master/docker/docker-compose-cop.yml
> https://github.com/hyperledger/fabric/blob/master/bddtests/docker-compose-next-4.yml
Unfortunately, none of these connect to #1 (COP) and #2 (Chain network).

hgabor
2017-01-05 09:43
I have a problem, I added fabric as a project, setup the compiler/sdk but there were unresolved references. E.g. it could not see things defined in other fabric modules. The reason was simple, my project was not in the GOPATH, as it is cloned into a folder called `git`, so it is `git/fabric` but it should be `GOPATH/github.com/hyperledger/fabric...`. I created a link in my /opt/go/src that is the GOPATH by default (the only element). This solves things but sometimes IntelliJ thinks that some modules are project external and if I add a new function it thinks it does not exist. What would be the non-hacky, official solution for this?
hgabor
2017-01-05 09:44
@benlewis I will try that plugin
thojest
2017-01-05 09:44
@jzhang ur right in that i was able to produce the argument error when using a 0.5.* version of hfc. but now even with a 0.6.* version i get this error i have posted
thojest
2017-01-05 09:47
i would be very happy if someone would have an educated guess what exactly is wrong. To be honest I dont really understand what the error message means. Looked into hfc source code but this is too advanced stuff...

@thojest I'm getting those same errors, but the code /seems/ to be working

2017-01-05 09:53
I ran it against my chaincode and got an error that I anticipated

2017-01-05 09:56
how did u modify app.js?

@thojest My plan is tro modify the function calls to see if they work on my chaincode. If they do, then I'll go from there

2017-01-05 10:01
ahh ur adapting app.js for your chaincode which u created yourself?
benlewis
2017-01-05 10:03
Yeah
thojest
2017-01-05 10:03
yeah i also have the impression that everything works but the peer still gives me these error messages
thojest
2017-01-05 10:05
maybe this is some logging problem that the messages cannot be sent to the peer node
benlewis
2017-01-05 10:06
Aside from a quirk unmarshalling data, my chaincode seems to be working despite the error messages
thojest
2017-01-05 10:06

2017-01-05 10:27
I have it set up to report events from chaincode. So for example, when a transaction completes, you can send data from chaincode to notify other programs
thojest
2017-01-05 10:29
u mean for example a signal to update a website or something like this
benlewis
2017-01-05 10:30
yeah
thojest
2017-01-05 12:24
@benlewis am i correct in assuming that the functions you define in app.js can be called from some button you implement on a webpage?
benlewis
2017-01-05 13:32
@thojest in theory, node hosts the webserver
benlewis
2017-01-05 13:34
so you can call functions based on that

@bfuentes how should I configure gopath properly with that? or how did you configure yours?
yacovm
2017-01-05 13:57
It's a special IDE that is essentially intelliJ
yacovm

I just code chaincode on it, not running anything locally. I deploy all on an Hyperledger docker image to see the errors in case
rahulhegde
2017-01-05 14:10
@muralisr I was able to deploy & invoke chaincode using dev mode using the peer image provided as part of connect-a-thon set for v1.0. Only thing - the peer CLI image blocks the query Interface. I will try this in my compiled PEER image. Did you get to check the error received via non-dev mode.
muralisr
2017-01-05 14:11
I didn’t unfortunately @rahulhegde … I got sidetracked
muralisr
2017-01-05 14:11
so I won’t make a rash promise beyond I have it in my list and will try it as soon as I can :slightly_smiling_face:
muralisr
2017-01-05 14:12
@rahulhegde that was for the remote deploy correct ? (just making sure as you indicated you are tryign other things as well)
hgabor
2017-01-05 14:13
@yacovm How do you configure gopath? Do you have your repo in /opt/go/src ? Or do you have it somewhere else (where GOPATH is set to) in a directory named http://github.com/hyperledger ? (the repo is just fabric) Mine is under some other directory and I don't want to move it or anything.

i have hyperledger v0.6 running and have written a simple chaincode everything works fine
thojest
2017-01-05 15:14
now comes the problem
thojest
2017-01-05 15:15
i want to create a webapp for it and i dont really know what would be the best way to get started. i have already looked in marbles get it working and had a look at the sourcecode on github
thojest
2017-01-05 15:15
and i have to admit that im a bit lost. has anyone a good approach for getting started writing a webapp for a hyperledger smart contract
thojest
2017-01-05 15:17
so basically i think one has to get started with writing a web app which is based on nodejs and then one can include the hfc sdk to interact with the code
thojest
2017-01-05 15:18
code meaning calling functions of the chaincode
thojest
2017-01-05 15:18
so to sum it up. what would you think is the best way to get started?
rahulhegde

In v1.0 architecture, Peer docker image compiled has Fabric-Runtime which is built with only busybox. Do we have the peer docker file changes which can also build /bin/bash in the compiled ` make peer-docker ` ?

Hi Thomas, @thojest if you’re writing a webapp then you’ll need a javascript program running in node.js. Fabric provides the HFC (Hyperledger Fabric Client) which is the SDK and provides the API to connect to the fabric network and deploy/query/invoke transactions.
One of the simplest examples is https://github.com/hyperledger/fabric/blob/v0.6/examples/sdk/node/app.js
If you want, you can deploy the chaincode manually, and then just query and invoke using the webapp.
You’ll need to use some previously registered users (see https://github.com/hyperledger/fabric/blob/v0.6/membersrvc/membersrvc.yaml), or the webapp can dynamically register them. The webapp will then need to do the one time enrolment which will store the credentials in the KeyValueStore.
thojest
2017-01-05 16:29
@dgorman thx a lot for this nice summary
thojest
2017-01-05 16:29
i think my mainproblem is creating a webpage with nodejs
thojest
2017-01-05 16:29
using stylesheets, html, javascript, .......
thojest
2017-01-05 16:30
so connecting to the smart contract using the api will probably be the smallest part.
thojest
2017-01-05 16:31
and at every corner ur confronted with some fancy new things, like css preprocessors and so on
thojest
2017-01-05 16:32
so if somebody knows some nice tutorial for uber n00bs like me would be very nice ^^
dgorman
2017-01-05 16:34
You’re welcome @thojest, yes it’s likely to be one of the easier parts in the webapp. This is another example which has a simple webapp front end. You could take this and build it out perhaps.
https://github.com/angrbrd/hyperledger-fabric-basics#hook-up-front-end
thojest
2017-01-05 16:35
@dgorman thx a lot this seems to be what i need
benlewis
2017-01-05 16:52
@thojest I've managed to get a site built and my code working with my chaincode, using a combination of app.js, the tutorial you sent me and some googling around using Jade (now known as Pug) for the webpage template

Not familiar with docker, is chaincode deployed to a respository as part of devop processes then chaincode deploy will tell docker to go fetch the new image and spin it up?
garisingh
2017-01-06 14:17
@jjohnst - simple answer is no. Longer answer is that a chaincode deploy transaction includes a Docker image archive (basically a tarball with the Dockerfile and any relevant contents - e.g. the chaincode source code).
Each peer then uses that the create a Docker image and then start a container based on that image
jjohnst
2017-01-06 14:18
perfect, thanks
jjohnst
2017-01-06 14:23
@garisingh sorry, one more question. Do you know if anyone has implemented the protocol spec in any other language then go?
ghaskins
2017-01-06 14:23
@garisingh yeah, except we need to change that :wink:
garisingh
2017-01-06 14:33
@jjohnst - we have clients for Node, Python and Java and you can build chaincode in both Java and Go. But for the actual "nodes" no one has built one in another language
jjohnst
2017-01-06 14:47
thx
garisingh
2017-01-06 14:51
I once thought about writing a peer implementation in Scala (just because I like Scala) but then lost interest in that idea :wink:
ghaskins
2017-01-06 14:52
@jjohnst while @garisingh is correct in his description of the current flow, do note that the fact that a Dockerfile is distributed around is an implementation detail, and one that needs to be changed...
ghaskins
2017-01-06 14:52
the operational model should be simply that src is distributed around the network, and each peer forms a docker container locally
ghaskins
2017-01-06 14:53
but to your point, we do not pull the docker image from a repo
ghaskins
2017-01-06 14:53
each peer is building it (even today)
garisingh
2017-01-06 14:53
@ghaskins - do we have a JIRA requirement for the "improvement"? Should not actually be hard to implement
ghaskins
2017-01-06 14:53
we might, let me look

@nickmelis : Use something like this in your docker compose file:
```
volumes:
- ./membersrvc.yaml:/opt/gopath/src/github.com/hyperledger/fabric/membersrvc/membersrvc.yaml
```
Then you can add the users that you want in the membersrvc.yaml file.
tkuhrt
2017-01-06 18:11
So in my docker compose file, I have something like this:
```
membersrvc:

ports:
- "7054:7054"
environment:
- CORE_VM_ENDPOINT=http://172.17.0.1:2375

general question: am referring the auction use case ( bcoz am planning to implement similar usecase on fabric ), in auction use case the items are moving from one person to other person when we query its shows only the current worldstate of the chain so question is 1) if i want to see complete audit trail for an item how can i query in fabric 2) when a record get stored in block it will have hash for that block, so when show the complete audit trail for an item i believe i should show the records with corresponding block hash, is my understanding is correct? 3) is it possible to get complete audit trail for an item by query block chain any time or do i need to store transaction in external db's by getting hash from block chain when write transaction into blockchain 4) for same use case is it possible to store the image in block chain ( consider my image size will be more than 20MB ) and get a hash for it and refer same hash in actual transaction
Appreciate your response in advance :slightly_smiling_face: your reply will really help me to implement use cases
muralisr
2017-01-08 17:20
@madhava `1) if i want to see complete audit trail for an item how can i query in fabric` - depends on which version of the fabric you are working on. 1.0 have plans to support advanced querying mechanisms (including history)…the ppt in https://jira.hyperledger.org/browse/FAB-758 has a few slides on it. Do check in fabric-ledger-dev for mode details
muralisr
2017-01-08 17:22
2) and 3) “audit trail” questions depend upon that history query question. `4) for same use case is it possible to store the image in block chain ` yes. That’s a useful pattern in fact
muralisr
2017-01-08 17:24
^^^ note that the above does not address “history” in 0.6. Broadly, no in-built support in the fabric for that in 0.6. You would have to either maintain it in chaincode state somehow or mine blocks for transactions related to the chaincode.
madhava
2017-01-08 17:30
Thanks @muralisr for your quick response, is 1.0 is a stable environment? as per community and my understanding its released week or 2 weeks back, as am any new to Fabric so may be its good idea to start with 1.0, please suggests. I just installed 0.6 on one node last week so i can cleanup that and go for 1.0
muralisr
2017-01-08 17:32
@madhava the support for history is not yet there in 1.0 so if that’s the aim, I’d say continue on 0.6
muralisr
2017-01-08 17:35
given you have started off on 0.6, in your shoes I’d stay on it
madhava
2017-01-08 17:38
Thanks once again @muralisr , one more request, am running chaincode02 and able to interact with cli, but am planning to interact with by exposing services through NodeJS do you have any reference on how to expose chain code as services, have installed HFC too
muralisr
2017-01-08 17:41
“expose as services” to mean expose some APIs using the NodeJS SDK to encapsulate invokes and queries to the chaincode as biz functions ?
muralisr
2017-01-08 17:43
@madhava I’d think code under `sdk/node/test/unit` in the fabric would help ?
madhava
2017-01-08 17:46
that's correct "invokes and queries to the chaincode as biz functions", through UI am planning to call these individual API's just by passing the required attributes
madhava
2017-01-08 18:10
@muralisr am just went through one or two examples in sdk/node/test/unit but i didn't find any functions exposed through post or get methods, my idea is use express module in NodeJS to expose these functions through post and get methods
muralisr
2017-01-08 18:11
ok
muralisr
2017-01-08 18:11
in that case an approach would be to use the REST api’s in the fabric directly in your nodejs
madhava
2017-01-08 18:12
yes do you have any reference for this can you please share it
muralisr
2017-01-08 18:13
I don’t have reference to using the REST api’s in a nodejs as example… maybe others have done that and can share ?
muralisr
2017-01-08 18:13
but are you looking for the REST api reference itself
muralisr
2017-01-08 18:13
?
madhava
2017-01-08 18:15
yes, bcoz i want my API's should be decoupled from UI so that i can reuse services in multiple places as needed
muralisr
2017-01-08 18:16
http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/ shows you how to use REST APIs (look for `Running the CLI or REST API`)
madhava
2017-01-08 18:16
so chain code is independent from services and UI is independent from API's
muralisr
2017-01-08 18:16
I’d start off without doing security
muralisr
2017-01-08 18:17
right, those REST api’s would be a good start to hook up into a nodejs app
madhava
2017-01-08 18:21
i went through above example but in those example we are sending everything in body including chaincodeID etc, rather my idea is expose services like GET
http://hostname:portnumber/menthodname?query or path param
muralisr
2017-01-08 18:22
perhaps wrap those in your nodesjs ?
madhava
2017-01-08 18:22
this way UI layer no need to know which chain code they need to call
madhava
2017-01-08 18:23
they just need to know the method which they need to call
muralisr
2017-01-08 18:23
sounds like a good approach… but better to tailor them to your app
muralisr
2017-01-08 18:23
as opposed to a generic api … but you could do either way I suppose
madhava
2017-01-08 18:24
ok let me check but Thanks for your help as always

@sibelius thanks, this his pointed me in the right direction, thanks. I was misunderstanding JavaScript callbacks
nickmelis
2017-01-09 11:02
@keithsmith I suspect the Docker images in the documentation still use v0.6, am I right?
sibelius
2017-01-09 11:02
javascript callbacks is a mess
sibelius
2017-01-09 11:02
u should use promises with async/await es7 feature
benlewis
2017-01-09 11:02
The example stuff from the fabric repo uses callbacks, so my plan was to follow on from that

@nickmelis are you running in development mode?
nickmelis
2017-01-09 11:04
@benlewis how do I check?
nickmelis
2017-01-09 11:04
I’ve just started peer and membersrvc using docker-compose
benlewis
2017-01-09 11:05
Ah okay, I'm not familiar with docker and v1.0 I've only used v0.6
nickmelis
2017-01-09 11:05
I’m not even sure docker images use v1.0 tbh
nickmelis
2017-01-09 11:06
@benlewis can you tell me about this dev mode? How do you enable it?
benlewis
2017-01-09 11:08
This has some details on using it with Java, but I've only used Golang, as despite the learning curve, there's more support
nickmelis
2017-01-09 11:10
do you know what the difference is between dev mode and non dev mode?
keithsmith
2017-01-09 11:28
@nickmelis In dev mode, you start the chaincode manually which gives you more control when debugging. In non-dev mode, the peer starts the chaincode container automatically for you when deployed.
nickmelis
2017-01-09 11:31
here’s another question: does the chaincode need to sit on the node in order for it to be deployed?
nickmelis
2017-01-09 11:31
I remember it was like this a few months ago
nickmelis
2017-01-09 11:32
but on other blockchain platforms (see Ethereum) you can compile the chaincode by yourself and then just send the bytecode to the blockchain
nickmelis
2017-01-09 14:00
@keithsmith , when you say “you start the chaincode manually”, what do you mean?
ghaskins
2017-01-09 14:13
@nickmelis its a bit of an (understandable) misnomer that the code had to be "on the node"
nickmelis
2017-01-09 14:14
so the path I am sending together with the transaction has to be the path of the chaincode on the node?
ghaskins
2017-01-09 14:14
really what was needed was the code had to be local to "your stack", which in the v0.6 architecture and prior _could_ include your NVP
ghaskins
2017-01-09 14:15
thats the misnomer part: you are sending a path relative to the SDK/NVP, not the peer cloud
ghaskins
2017-01-09 14:15
it was confusing, and many many people got hung up on this (myself included)
nickmelis
2017-01-09 14:16
ok that’s what I thought. But even though I am sending the path of the chaincode on the SDK node (the app), I get this error on the node:
nickmelis
2017-01-09 14:16
vp0_1 | 13:43:15.315 [chaincode] Launch -> ERRO 6af sending init failed(handler not found for chaincode myccj)
ghaskins
2017-01-09 14:16
in that architecture, the NVP was supposed to be considered part of your client, not the peer cloud
ghaskins
2017-01-09 14:16
hmm, ok, well that is something else I think
nickmelis
2017-01-09 14:17
in fact the SDK doesn’t blow up, just receives a chaincode response status = UNDEFINED
ghaskins
2017-01-09 14:17
ive not seen that: are you running v0.6 or master?
nickmelis
2017-01-09 14:18
SDK is from master, node is running using docker-compose and the docker images fabric-peer and fabric-membersrvc from the documentation
nickmelis
2017-01-09 14:18
now I’m not 100% sure those images from DockerHub are from master rather than v0.6
nickmelis
2017-01-09 14:19
do you have any idea?
ghaskins
2017-01-09 14:20
the only images on dockerhub are v0.6 to my knowledge
ghaskins
2017-01-09 14:20
(and generally, I have been the one publishing them)
ghaskins
2017-01-09 14:20
though it is possible someone else released something without me knowing, but its not likely
ghaskins
2017-01-09 14:21
i think that might be part of your problem though...i do not think the master SDK is compatible with v0.6
ghaskins
2017-01-09 14:21
if you are using v0.6, I would use HFC v0.6.5 from npm
ghaskins
2017-01-09 14:21
I've built POCs with that combo and it works well, fwiw
nickmelis
2017-01-09 14:23
ok here’s the question then: can I build v1.0 docker images myself?
nickmelis
2017-01-09 14:23
so that I can use master SDK with master fabric?

@nickmelis - the Fabric Makefile has targets for just building the Docker images - so yes

ok something has definitely changed now, I am now getting “Failed getting a new TCert”. Suspect it’s something to do with the membersrvc?
ghaskins
2017-01-09 15:12
@nickmelis: just do "make docker" and it will make the images for v1.0 locally

@ghaskins thanks for the tip. Have you got any idea what may be causing the error with the TCert? There’s no clue in HL log, just this log in the SDK
ghaskins
2017-01-09 15:20
no, are you running cop?
nickmelis
2017-01-09 15:20
I’m running the images from https://github.com/yeasy/docker-blockchain-explorer
nickmelis
2017-01-09 15:21
which are supposed to be built from the master branch
ghaskins
2017-01-09 15:23
ah, ok, i am not familiar with what yeasy published
nickmelis
2017-01-09 15:23
would you suggest to create my images myself by building them locally?
ghaskins
2017-01-09 15:24
i guess the short answer is: if you are trying to do v1.0 work with the SDK, I would do whatever the v1.0 SDK folks do :wink:
ghaskins
2017-01-09 15:24
I was trying to get this stood up last week, and I am pretty close, I but I am certainly no expert
ghaskins
2017-01-09 15:24
but that was the approach I took
nickmelis
2017-01-09 15:24
and how do I get to know what the SDK folks do? :slightly_smiling_face:
nickmelis
2017-01-09 15:25
note SDK is Java SDK here
ghaskins
2017-01-09 15:25
best to start with either @jzhang or #fabric-sdk-node-dev
ghaskins
2017-01-09 15:25
ah, ok
ghaskins
2017-01-09 15:25
well, then I am not sure
nickmelis
2017-01-09 15:27
as far as you know, is there any docker v1.0 image out there?

as I mentioned earlier, I am involved with the official images and I do not believe there are any official v1.0 releases floating around
ghaskins
2017-01-09 15:31
there certainly could be derivative repos out there that I am not aware of though
ghaskins
2017-01-09 15:32
it does appear there is a #fabric-sdk-java channel though
ghaskins
2017-01-09 15:32
perhaps start there
nickmelis
2017-01-09 15:35
yeah makes sense
nickmelis
2017-01-09 15:35
so all the v1.0 docker images out there (if any) are “non official”, right?
nickmelis
2017-01-09 15:35
I might as well build my own image then
ghaskins
2017-01-09 15:42
yeah...I was actually just working on cleaning up the fabric-cop image actually
ghaskins
2017-01-09 15:42
so, I know the fabric-peer/fabric-orderer are in good shape...just check out fabric.git and "make docker"
ghaskins
2017-01-09 15:42
soon, same for cop
ghaskins
2017-01-09 15:42
as far as java-sdk particulars, you'd have to ask the java devs
ghaskins
2017-01-09 15:42
I use node-sdk myself
nickmelis
2017-01-09 15:43
cop is the old membersrvc right?
ghaskins
2017-01-09 15:43
right
nickmelis
2017-01-09 15:43
does it mean cop is not ready yet?
ghaskins
2017-01-09 15:43
fabric-cop.git is what was formerly fabric.git/membersvc, IIUC
ghaskins
2017-01-09 15:43
no, sorry didnt mean to imply that
ghaskins
2017-01-09 15:43
I think cop probably runs fine stand alone, I was trying to improve the dockerization of it
ghaskins
2017-01-09 15:44
again, this is newly emerging understanding for me too (as of Friday) so I am not the best source
ghaskins
2017-01-09 15:44
best source would be to ask the x-sdk devs what they do
nickmelis
2017-01-09 15:44
ok so if I wanted to stick with v1.0 I should be able to build fabric and fabric-cop as docker images right?
ghaskins
2017-01-09 15:45
def fabric, probably fabric-cop, I should have my patch which makes fabric-cop image a little more turn key shortly
ghaskins
2017-01-09 15:45
as in, today
ghaskins
2017-01-09 15:45
ill ping you when I push the CR

also I hope I can get in touch with someone from the Java SDK
jonathanlevi
2017-01-09 15:58
@nickmelis: Indeed, if you want to work with the very latest, right now - you can build the images on your own. Things are “in the making” and every week, we get more stuff that is better tested, (relatively!) more stable, better documented, etc. Also, you may want to join #fabric-cop and #fabric-sdk-java and other channels. Just ask around, and we’ll point them out to you.

Hi All, we use Hyperledger 0.6 version, in the blockchain app we are building, during chaincode deployment we do other things like creating table, creating cache, populating metadata etc.,
the problem is, when lets say the deploy request fails, we are not sure whether its related to the image/core issue or some problem with the code that we wrote. Because even to get a log we should have a chaincode id, which is possible only when the deploy is successful. Is there a way out for solving this issue.

@subax I may be having the same problem, what’s in the node log? What’s the error?

@nits7sid C-C interaction is not possible with privacy on in v0.6. That said, note that the security model is different in 1.0 so better to have a migration plan. The approach I’d take is to not rely upon privacy being turned on in 0.6. For more info do check with fabric-crypto

Chain allows interoperability between different instances e.g. Alice creates asset X in Bank A’s Chain. Bob is a user in Bank B’s Chain. Alice can send pieces of her asset to Bob even though it’s on another Chain. Is this kind of interoperability in the scope for Fabric 1.0?

I've gone through everything in the host_marbles_bluemix guide to get it running, but I'm getting this error when running `cf push <app>`. The webapp works, but the chaincode fails to deploy. Have I missed something that's not covered here: https://github.com/IBM-Blockchain/marbles/blob/v2.0/docs/host_marbles_bluemix.md

@muralisr, @garisingh I was looking at the same issue and working with @sneha. There is gRPC error from orderer when it tries to send the Deploy Transaction Block to Peer. Port exposed by peer by default is 7051. However orderer uses the right docker container IP of Commiter Peer (which is also endorser for 1 Peer Setup) but a different port (48144 and randomly in increasing order). This results in write broken pipe error. How does Orderer know about the list of Committer Peers (IP, Port) on the Hyperledger network, is there a way can provide more debug information or is there a known solution?
Setup: Fabric {peer, cop and orderer} images are used from the connect-a-thon - v1.0 architecture and is currently used to run a custom-helloworld-chaincode using DEV mode.
Secondly - I have tried this on Linux box hosted on AWS and has never seen this problem however on our internal organization boxes (Intranet one of the environment difference), we see this error almost frequently.
joee

Chain allows interoperability between different instances e.g. Alice creates asset X in Bank A’s Chain. Bob is a user in Bank B’s Chain. Alice can send pieces of her asset to Bob even though it’s on another Chain. Is this kind of interoperability in the scope for Fabric 1.0?
cbf
2017-01-14 18:54
@joee Fabric v1.0 has the notion of channels, which could be leveraged, I believe in the manner you suggest
garisingh
2017-01-14 18:54
@muralisr - if running in dev mode, what's the env variable you need to set on the chaincode and/or peer side?
garisingh
2017-01-14 18:54
I have a feeling that might be the issue @sneha is facing? at least I've seen that before
muralisr
2017-01-14 18:55
@garisingh reading...
garisingh
2017-01-14 18:56
@warm3snow - you need docker-compose 1.8 or above
muralisr
2017-01-14 18:58
right I was not sure of the configurations here…contradictions in two comments made me pause (1) `There is gRPC error from orderer when it tries to send the Deploy Transaction Block to Peer.` from @rahulhegde and (2) `Registration and deployment of chaincode is successful.` from @sneha
muralisr
2017-01-14 18:58
and `I was looking at the same issue and working with @sneha.` from @rahulhegde
muralisr
2017-01-14 18:59
sounded like different problems but from same configuration ….
muralisr
2017-01-14 19:01
also `images are used from the connect-a-thon - v1.0 architecture ` from @rahulhegde … the devmode env variables in latest master might be slightly different than with images used in connect-a-thon (the chaincode needs to register with the fully qualified namespace “mycc:0/**TEST_CHAINID**”)
muralisr
2017-01-14 19:02
I wanted to wait till I heard back from @sneha
garisingh
2017-01-14 19:04
gotcha
muralisr
2017-01-14 19:47
@garisingh @rahulhegde @cbf https://jira.hyperledger.org/secure/attachment/10378/peerchaincodedev_in_1.0.txt added to JIRA item fab-37 … also accessible from https://wiki.hyperledger.org/community/fabric-design-docs
rahulhegde
2017-01-14 21:40
@muralisr @garisingh
We have followed the same steps >quote https://jira.hyperledger.org/secure/attachment/10378/peerchaincodedev_in_1.0.txt >quote using the images from the connect-a-thon/marble application. There is no multi-chain that is tried in our steps (i.e. no-chain id specified) and I doubt these images support it.
Coming to the scenario
Though @sneha mentions chaincode deployment is success ` CORE_CHAINCODE_MODE=dev peer chaincode deploy -n mycc -c '{"Args":["init","a","100","b","200"]}' ` . Looking at Peer CLI logs it gives a impression that deployment is really successful and at the same time chaincode init method returns no error prints in the chaincode running window.
So performing next step ` send an invoke ` after restarting chaincode fails with the message as put by Sneha ` Error: Error endorsing chaincode: rpc error: code = 2 desc = Error deploying chaincode: Failed to launch chaincode spec(Failed to init chaincode(handler not found for chaincode mycc)) ` .
And the main reason I see from logs, the Orderer Service itself failed to pass the Deploy Transaction back to the Peer thus actually completing the deployment cycle of Chaincode. Following is the error seen in the orderer logs.
` grpc: Server.Serve failed to create ServerTransport: connection error: desc = "transport: write tcp 172.18.0.2:7050->172.18.0.4:38084: write: broken pipe" `
muralisr
2017-01-14 21:41
so
muralisr
2017-01-14 21:41
@rahulhegde you are using docker … and the instructions just posted are for running in vagrant
rahulhegde
2017-01-14 21:43
yes - running using docker, does it matter @muralisr
muralisr
2017-01-14 21:43
the instructions would have to be modified a bit
muralisr
2017-01-14 21:43
using docker container ids and `docker inspect <container id>` we can get IP addresses for `peer` and `orderer`
rahulhegde
2017-01-14 21:44
yes - this is taken care.
muralisr
2017-01-14 21:44
the CLI commands would have to be modified to point to those addresses
muralisr
2017-01-14 21:44
so for example
muralisr
2017-01-14 21:44
`CORE_CHAINCODE_MODE=dev peer chaincode deploy -n mycc -c '{"Args":["init","a","100","b","200"]}’` would change to
muralisr
2017-01-14 21:44
`CORE_PEER_ADDRESS=<peer ip>:<exported peer port> CORE_CHAINCODE_MODE=dev peer chaincode deploy -n mycc -c '{"Args":["init","a","100","b","200"]}’`
muralisr
2017-01-14 21:45
actually no
muralisr
2017-01-14 21:45
you’d also need to orderer address...
muralisr
2017-01-14 21:46
`CORE_PEER_ADDRESS=<peer ip>:<exported peer port> CORE_COMMITTER_LEDGER_ORDERER=<orderer ip>:<exporteded orderer port> CORE_CHAINCODE_MODE=dev peer chaincode deploy -n mycc -c '{"Args":["init","a","100","b","200"]}’`
muralisr
2017-01-14 21:46
and finally
rahulhegde
2017-01-14 21:47
yes Murali. Connect-a-thon images had the docker-composer file and had the YML file pre-configured.
muralisr
2017-01-14 21:48
and you are running `peer chaincode deploy` from vagrant ?
rahulhegde
2017-01-14 21:48
So Peer, Orderer and Cop images are pre-configured. The additional step run are the one - you provided. This is also run using the actual peer IP:Port
muralisr
2017-01-14 21:48
or from another docker container
rahulhegde
2017-01-14 21:49
Everything is from Docker Container.
rahulhegde
2017-01-14 21:50
Also - I have run the same setup on the AWS instance hosting a Linux RHEL VM. I did see ` grpc: Server.Serve failed to create ServerTransport: connection error: desc = "transport: write tcp 172.18.0.2:7050->172.18.0.4:38084: write: broken pipe" ` but the frequent of these messages is very very less.
rahulhegde
2017-01-14 21:50
So on AWS Linux RHEL instance - I was able to run my custom chaincode (Deploy + Invoke) and also with 2 PEER setup.
rahulhegde
2017-01-14 21:51
This problem aggravates very much on the environment which is hosted on Intranet (our development boxes).
rahulhegde
2017-01-14 21:52
I hope we are now sync?
rahulhegde
2017-01-14 21:52
Our internal intranet hosted environment are also RHEL.
muralisr
2017-01-14 21:57
@rahulhegde I’m not sure of all the dynamics here, but I’d say first step is to make sure the various containers can talke to each other and the envs (the `CORE_…` envs) are setup correctly to point to various processes
rahulhegde
2017-01-14 22:02
@muralisr @garisingh My understanding the setup w.r.t. IP, Port and ENV for DEV mode run is all correct. Like if I restart Peer, I do see a communication happening between Peer <--> Orderer successfully. However when a Transaction is sent for committing to the Ledger (in this case Deploy Transaction as per our scenario described), Orderer gets the correct IP of the Peer but the Port used is completely different and it gives the gRPC error. This is tried by the Orderer with correct IP but a increasing Port number.
rahulhegde
2017-01-14 22:04
How does the Orderer get the Peer endpoint information for communication - is it at the start-up Peer talks to the Orderer and registers this information?
muralisr
2017-01-14 22:32
it is the Peer who opens up communication with the oredre
muralisr
2017-01-14 22:33
so orderer does not have to know “endpoint” information of the peer
muralisr
2017-01-14 22:34
@rahulhegde it does sound like a configuration / setup issue (as opposed to a correctly setup env but failing sporadically) … I could be wrong of course (for example a flaky network might cause certain issues)
muralisr
2017-01-14 22:35
we’d need proper docs (for example, if you are using docker compose the composition files) to understand what’s happening
rahulhegde
2017-01-14 23:05

It gets the error first and then the Block gets passed to the Peer- somehow it is able to send it to Peer. I can see from the next 'invoke', world-state ledger contains updated value.

Another snapshot at a different time.
garisingh
2017-01-14 23:34
the connection between the peer(s) and the orderer seem to be breaking. Do you see anything in the peer logs? I assume that `172.18.0.2:7050` is the orderer?
garisingh
2017-01-14 23:36
The "random" ports you see are the ephemeral ports used by the peer on its end when creating the connection to the orderer. The GRPC connection is full duplex (meaning either side can initiate sending information) - so the low level GRPC error is misleading - it trying to send data over the existing connection which appears to be broken
rahulhegde
2017-01-14 23:42
Yes the logs put are from the Orderer having endpoint ` 172.18.0.2:7050 ` , I don't see any error in the log of the 1-Peer setup environment having endpoint configured as ` 172.18.0.4:7051 `

Had a call with Murali (thanks for your time) and concluded there is no issue with the setup between peer and orderer. As suggested by Murali, I will post this problem on the #fabric-consensus-dev so this can be picked by you with the Consensus team for suggestion of any quick workaround.

@muralisr @garisingh as https://jira.hyperledger.org/secure/attachment/10378/peerchaincodedev_in_1.0.txt for chaincode running DEV mode, do we have steps to try to launch chaincode in non-dev or production mode? If I see the orderer logs of connect-a-thon setup done on our intranet (chaincode running in non-dev mode), for >20 blocks it hasn't thrown gRPC error.

2017-01-15 23:38
Let me check
rahulhegde
2017-01-15 23:41
Q: Peer CLI use of -p and installing using 'go get' isn't deprecated for v1.0?
Q: if -p option is supported - can I pass a local path to the chaincode source code?
rahulhegde
2017-01-15 23:53
I tried the non-dev mode with connect-a-thon image of PEER and it dies down during ` go get `

muralisr
2017-01-16 01:08
@rahulhegde I guess you were trying remote ?
rahulhegde
2017-01-16 01:25
@muralisr didn't get the remote note. I am trying to exec to the peer docker container and then executing the deploy using -path to github.
muralisr
2017-01-16 01:26
@rahulhegde I’m trying to get hold of the connectathon source
muralisr
2017-01-16 01:27
did you get a chance to try with master ?
rahulhegde
2017-01-16 01:28
not yet from master.
rahulhegde
2017-01-16 01:29
my recent run on marble application shows that peer running chaincode in non-dev mode; the orderer of the connect-a-thon never threw a gRPC error
rahulhegde
2017-01-16 01:30
if I can complete the launching of my 'custom' chaincode via non-dev mode, I think at least I should proceed with chaincode development.
muralisr
2017-01-16 01:31
for non-dev mode just have to remove the —peer-chaincodedev flag in the peer
muralisr
2017-01-16 01:32
and not use the CORE_CHAINCODE_MODE=dev flag in the deploy / invoke commands
rahulhegde
2017-01-16 01:32
how will the peer get the path of the chaincode when run via Peer CLI?
muralisr
2017-01-16 01:32
it should be in the gopath in the CLI
muralisr
2017-01-16 01:33
however I have not run in docker env recently
rahulhegde
2017-01-16 01:33
-p $GOPATH/src/custom-chaincode ?
rahulhegde
2017-01-16 01:34
this path will hold the actual chaincode source file
rahulhegde
2017-01-16 01:34
But I am stuck with the segmentation fault as put above.
muralisr
2017-01-16 01:34
what is your CLI command ?
rahulhegde
2017-01-16 01:35
peer chaincode deploy -n mycc -p https://github.com/rahulhegde/learn-chaincode/start -c '{"Args":["init","100"]}'
muralisr
2017-01-16 01:35
do you have the source locally ?
muralisr
2017-01-16 01:35
in your gopath
muralisr
2017-01-16 01:36
ie under $GOPATH/rahulhegde/learn-chaincode/start ?
muralisr
2017-01-16 01:36
if you do
rahulhegde
2017-01-16 01:36
Let me check now - I think I didn't expose from the container.
muralisr
2017-01-16 01:36
try `peer chaincode deploy -n mycc -p http://github.com/rahulhegde/learn-chaincode/start -c '{"Args":["init","100"]}’`
muralisr
2017-01-16 01:36
yes
muralisr
2017-01-16 01:36
export the volume and try it
muralisr
2017-01-16 01:37
again, I have not tried in peer running in docker
muralisr
2017-01-16 01:37
if you can try in master it’ll be be easier to debug these issues
rahulhegde
2017-01-16 01:40
yes - I will try now exposing the volume.
Also, I have compiled Peer and Orderer from master branch - I can give try on this too as per u r steps but not using Vagrant due to VM issue.
rahulhegde
2017-01-16 01:41
BTW - why do u need to expose chaincode source if Peer CLI is trying to do ` go get ` from network?
rahulhegde
2017-01-16 01:55
@muralisr - good part i didn't get segmentation fault after volume mapping however the below error

@rahulhegde .. what do you see in peer.log (I assume you are running in docker )
rahulhegde

Just pasting the last logs where it shows error. Yes Murali inside the docker.

rahulhegde
2017-01-16 02:03
My understanding - successful deployment will spin a new docker container running the chaincode.
muralisr
2017-01-16 02:03
`user runs chaincode, not deploying chaincode`
muralisr
2017-01-16 02:03
sounds like `—peer-chaincodedev` is still there ?
rahulhegde
2017-01-16 02:04
yes - :disappointed: let me fix that.
muralisr
2017-01-16 02:04
ok
muralisr
2017-01-16 02:05
also make sure not to use CORE_CHAINCODE_MODE in the CLI commands
rahulhegde
2017-01-16 02:06
yes - none of the 3 ENV will be used.
rahulhegde
2017-01-16 02:11

```
I received ccenv as part of connect-a-thon image set, should I tag that image with the above required tag OR is the way I can say use ` hyperledger/fabric-ccenv:latest `?
Does the above behavior get influenced by core.yml configuration
```
golang:

rahulhegde

My master compiled branch also contains ccenv but I don't think I should use it (by retagging the below)

```
My cc-env ~ 1.4G and the peer log scroll has stopped with above message but my Peer CLI logs are scrolling - not sure what is happening
rahulhegde
2017-01-16 03:19
Thanks @muralisr. I am able to see the chaincode spin in a different docker container now and have run almost 20 invoke w/o any gRPC error. From this activity, it looks there is some defect on PEER when run in peerchaincode dev mode for connect-a-thon image.
I need to try the same on my intranet and have few questions on this, which I will ask you!!! Thank You.

@garisingh the good news is that I was indeed able to build cop on Windows, natively
arnaud
2017-01-16 11:35
the bad news is that the unit-tests don't pass, is that expected? that seems true in Vagrant just the same so I don't think this is Windows specific
arnaud
2017-01-16 11:54
it seems that the problem comes from trying to rerun the same test
arnaud
2017-01-16 11:54
or tests
arnaud
2017-01-16 11:58
yup
arnaud
2017-01-16 11:58
if I rm testdata/cop.db and rerun the test it passes
garisingh
2017-01-16 12:06
hmm - ironically I am getting a lint error now
arnaud
2017-01-16 12:06
so here is the deal, tests pass if I delete the db between each package
arnaud
2017-01-16 12:08
so "gocov test $PKGS" fails, but "for i in $PKGS;do rm -f testdata/cop.db; gocov test $i;done" works
arnaud
2017-01-16 12:08
apparently it has to do with trying to enroll the same user multiple times
arnaud
2017-01-16 12:09
make lint works for me
garisingh
2017-01-16 12:21
did you run `make unit-tests`
arnaud
2017-01-16 12:23
yes
garisingh
2017-01-16 12:25
past the lint error - now running `make unit-tests` twice in a row
arnaud
2017-01-16 12:25
I can't even pass it once
garisingh
2017-01-16 12:26
I passed once
garisingh
2017-01-16 12:26
(I'm on OSX as that's what I have been using so just want to stay consistent)
arnaud
2017-01-16 12:26
for me it fails on TestAllClient
arnaud
2017-01-16 12:27
I'm running natively on Windows
arnaud
2017-01-16 12:28
which is part of the lib test
garisingh
2017-01-16 12:28
right - I just want to make sure that nothing that was working is broken :wink: although the lint error is odd - I've seen it before but than it went away
arnaud
2017-01-16 12:29
I'll try again on Vagrant to see what I get
garisingh
2017-01-16 12:29
I'm going to check in a fix anyway - the lint error actually showed a poor line of code :wink:
arnaud
2017-01-16 12:29
in any case we're not far of having it functioning on Windows
garisingh
2017-01-16 12:30
I ran the tests twice in a row with no issues. my best guess is that we have a Unix specific file command in the code
arnaud
2017-01-16 12:30
yeah...
arnaud
2017-01-16 12:31
there is also a test that fails: --- FAIL: TestMakeFileAbs (0.00s)
util_test.go:235: Absolute of file=/a/b/c with dir= expected /a/b/c but was C:\a\b\c
util_test.go:235: Absolute of file=c with dir=/a/b expected /a/b/c but was C:\a\b\c
util_test.go:235: Absolute of file=../c with dir=/a/b expected /a/c but was C:\a\c
FAIL
FAIL http://github.com/hyperledger/fabric-cop/util 0.972s
arnaud
2017-01-16 12:31
typical unix specific code :slightly_smiling_face:
arnaud
2017-01-16 12:32
I'll see what needs to be done for that one
arnaud
2017-01-16 12:32
there should be a Go function that allows to deal with that difference
garisingh
2017-01-16 12:52
you can probably use `filepath.Clean()` around the expected result in the test
arnaud
2017-01-16 13:38
that doesn't do, but filepath.Abs() on the expected value does the trick
garisingh
2017-01-16 13:43
yeah - I found that too
garisingh
2017-01-16 13:43
unfortunately, I was trying to avoid having to deal with the error return :wink:
arnaud
2017-01-16 14:12
you can ignore the error :slightly_smiling_face:
arnaud
2017-01-16 14:12
which makes it work even for the special case of ""
arnaud
2017-01-16 14:13
a bit hacky but where is the fun otherwise? :wink:
arnaud
2017-01-16 14:13
one has to leave room for more bugs to crawl
arnaud
2017-01-16 14:14
the unit tests don't pass on vagrant either
arnaud
2017-01-16 14:14
but for different reasons
arnaud
2017-01-16 14:14
I fixed one - in the tests
arnaud
2017-01-16 14:23
@garisingh is it intentional that the server_test.go cleans up cop.db but not client_test.go?
arnaud
2017-01-16 14:24
I don't know how that works on Mac
arnaud
2017-01-16 14:24
in my case, whether on Windows or vagrant the tests trip over reusing the db
keithsmith
2017-01-16 14:26
@arnaud It is not intentional. It should be cleaned up. I've added cleanup code in client_test.go in multiple change sets but somehow keeps getting removed. (I just saw this conversation on fabric)
arnaud
2017-01-16 14:27
hi keith, I actually thought I was on #fabric-cop, my bad
arnaud
2017-01-16 14:27
I'll switch channel
nickmelis
2017-01-16 14:43
is anyone familiar with java chaincode and tables?
nickmelis
2017-01-16 14:44
(may be similar to go chaincode though)
nickmelis
2017-01-16 14:44
is there a way to select more than one rows using some criteria rather than only getting one single row by key?
nickmelis
2017-01-16 14:48
actually I see the go chaincode stub has a getRows method, whereas the java one doesn't
thojest
2017-01-16 15:06
question: when i deploy chaincode in non-dev mode then this deploy returns a cryptic hash which i have to use for invokes
thojest

is there a more elegant version to invoke or query the chaincode without using this superlong hash for addressing the chaincode ?
vadim
2017-01-16 15:08
try using the —name flag
vadim
2017-01-16 15:08
peer chaincode deploy -n “something"
thojest
2017-01-16 15:08
i though when using non dev mode you cannot use -n ?
vadim
2017-01-16 15:08
I’m not aware of such limitation
thojest
2017-01-16 15:09
i ll try it thanks
thojest
2017-01-16 15:12
hmm i think -n only works for node with `--peer-chaincodedev`
vadim
2017-01-16 15:13
it’s probably on 0.6.1
thojest
2017-01-16 15:13
yepp im using v0.6
vadim
2017-01-16 15:13
seems that the last fabric does allow using —name in prod mode
thojest
2017-01-16 15:14
at least this cryptic hash stays the same in every deployment :slightly_smiling_face: im fine with that
vadim
2017-01-16 15:14
as long as you dont change your chaincode
thojest
2017-01-16 15:14
ok, nice to know
thojest
2017-01-16 16:11
is there anywhere an example for how the communication between a nodejs app and the chaincode works using hfc sdk
thojest
2017-01-16 16:11
?
thojest
2017-01-16 16:11
specifically, how do i call a function of the chaincode in the nodejs app
vadim
2017-01-16 16:16
I could suggest to read the end-to-end test found in the fabric-sdk-node repo: https://github.com/hyperledger/fabric-sdk-node/blob/master/test/unit/end-to-end.js
vadim
2017-01-16 16:17
However, I’m not sure whether it would work with 0.6
vadim
2017-01-16 16:19
Maybe this would work: http://fabric-sdk-node.readthedocs.io/en/latest/sample-web-app/
thojest
2017-01-16 16:40
i think that this here is quite useful https://github.com/IBM-Blockchain/SDK-Demo/blob/master/helloblockchain.js
thojest

*Who ensures endorsement results match in Fabric 1.0?* If the client requests endorsements from 3 Endorsing Peers, and they all run the chaincode and provide the response, does the client have to check whether all the responses match, before sending the endorsements to the Ordering Service? Or does the client only have to check whether or not enough endorsements have arrived?
Does the SDK perform these checks or does the client have execute custom code to perform these checks?
markparz
2017-01-16 21:30
@yashgt …. @muralisr can confirm, the SDK would check to verify you have the proper number of signed endorsements based on the policy you set. I don’t know what you mean by “whether all the responses match”.
silliman
2017-01-16 22:12
@markparz I don't know the answer to this myself, but I suspect that what @yashgt means is this- Do I, the client, have to check if the values in the ReadSets and/or ReadWriteSets that are returned from each endorsing peer in the Transaction proposal response are identical, or will the SDK do this for me "under the covers" ?
julio
2017-01-17 00:45
Hi. To anyone who knows, is (or will) there be a beta release for v1?
yashgt
2017-01-17 01:01
@markparz, @silliman has described my question accurately.
muralisr
2017-01-17 01:04
@yashgt the final “validation” of endorsement happens on the peer itself at commit time using the endorsement policy for the chaincode for each TX when the block with the TX reaches the peer
muralisr
2017-01-17 01:05
the application using the SDK can perform validations too (but they are not expected and cannot in general do Read/Write set validation as these are not at the “application” level)
muralisr
2017-01-17 01:09
as @markparz pointed out the SDK can do endorsement checks too (and probably a good thing if it does to save work on the aforementioned commit-time validation)
ghaskins
2017-01-17 02:35
@muralisr I took the above question not so much as it imply the SDK can or should perform validation on the output set itself, as much as a question of whether it (the client or the SDK) is comparing the consistency of the outputs
ghaskins
2017-01-17 02:35
thats something I would be curious about as well
ghaskins
2017-01-17 02:36
e.g. can/should the client/SDK ensure that either all or "enough" endorsers derived the same RWS

what’s the advantage of writing into the state instead of storing a map in the chaincode itself?
vadim
2017-01-17 09:26
it won’t be in the blockchain if you store it in the chaincode
thojest
2017-01-17 09:28
found it it is in the doc folder :smile: :smile:
thojest
2017-01-17 10:27
when using hyperledger without security enabled i can deploy and invoke without referring to a special user
thojest
2017-01-17 10:27
is this also possible using hfc sdk
thojest
2017-01-17 10:28
so that i can use `deploy()` without having a user?
thojest
2017-01-17 10:45
so can i use hfc sdk without the membersrvc servcie
dsanchezseco
2017-01-17 12:03
is someone playing with Certs attributes?
dsanchezseco
2017-01-17 12:03
cause i'm seeing this https://github.com/hyperledger/fabric/blob/master/docs/API/AttributesUsage.md
dsanchezseco
2017-01-17 12:08
and the firsts questions i have are,
1. it says the attributes are validated by the ACA, but then on the example are sended on the json? are still validated againts the ACA? if they are different are them discarded? I suppose the attributes should be stored on the yaml of the memberserv along with the enrollID/secret, right?
2. can i use them to gather the identity of the invoker of the chaincode to have access control instead of based on atributtes based on identity?
xixuejia
2017-01-17 12:29
Hi all, I want to update my chaincode from v0.5 to v0.6, how can I migrate data(blocks, state) ? Is there any best practice or existing tool to do that?
vadim
2017-01-17 12:34
@dsanchezseco you can get identity in chaincode (caller cert) by calling stub.getCallerCertificate()
dsanchezseco
2017-01-17 12:35
but does change through calls right?
vadim
2017-01-17 12:35
if you use tcerts
dsanchezseco
2017-01-17 12:35
and how to change to ecerts?
vadim
2017-01-17 12:36
just sign it with ecert
vadim
2017-01-17 12:36
but ecert will not have attributes
dsanchezseco

hey guys im trying to deploy a chaincode using hfc sdk
thojest
2017-01-17 13:52
this is the error im getting
thojest
2017-01-17 13:53
`request = {"fcn":"init","args":["50","300"],"chaincodePath":"settlement/"}
error = {"error":{"code":2,"metadata":{"_internal_repr":{}}},"msg":"Error: sql: no rows in result set"}
`
thojest
2017-01-17 13:53
can anyone help me, what am i doing wrong
thojest
2017-01-17 13:54
i try to deploy with the following function
thojest
2017-01-17 13:54
`function deploychaincode(err, deployuser) {
var deployRequest = {
fcn: "init",
args: ["50", "300"],
chaincodePath: "settlement/"
};
var deployTx = deployuser.deploy(deployRequest);
deployTx.on("complete", function(results){
chaincodeID = results.chaincodeID;
console.log("\nChaincode ID: " + chaincodeID);
console.log(util.format("\n Successfully deployed chaincode\nrequest = %j\n response = %j", deployRequest, results));
fs.writeFileSync(chaincodeIDPath, chaincodeID);
});
deployTx.on("error", function(err) {
console.log(util.format("\nFailed to deploy chaincode\nrequest = %j\n error = %j", deployRequest, err));
});
}`
vadim
2017-01-17 13:57
are you able to deploy your chaincode over console?
thojest
2017-01-17 13:57
yes
thojest
2017-01-17 13:58
i think it has to do with my deploy request
thojest
2017-01-17 13:58
is chaincodepath absolute or relative or dependent on go path ?
vadim
2017-01-17 13:58
it should be relative to gopath
thojest
2017-01-17 13:58
do i need chaincodeid or chaincodename?
vadim
2017-01-17 13:59
I think it should be generated
vadim
2017-01-17 13:59
at least it’s not in the example https://github.com/IBM-Blockchain/SDK-Demo/blob/master/helloblockchain.js
thojest
2017-01-17 13:59
do i need certificatepath even when security is off ?
thojest
2017-01-17 13:59
yeah thats exactly what im looking at
vadim
2017-01-17 14:00
I think it must be more or less the same parameters you use in console
thojest
2017-01-17 14:02
hmm how do i find out what this error means?
vadim
2017-01-17 14:04
you see any errors at peer?
thojest
2017-01-17 14:05
no unfortunately not
vadim
2017-01-17 14:14
just a guess: maybe the hfc incorrectly interprets the empty result from your chaincode init function
vadim
2017-01-17 14:14
try returning something there other than nil
thojest
2017-01-17 14:17
ok ill try that
thojest
2017-01-17 14:26
hmm unfortunately it does not work
thojest
2017-01-17 14:26
however i can successfully enroll and register users
thojest
2017-01-17 14:28
`test`
thojest
2017-01-17 14:29
is the deploy request
thojest
2017-01-17 14:29
var deployRequest = {
fcn: "init",
args: ["50", "300"],
chaincodePath: "settlement"
};
thojest
2017-01-17 14:29
is it correct or am i missing something
thojest
2017-01-17 14:29
this is the equivalent
thojest
2017-01-17 14:30
`peer chaincode deploy -c '{"Args": ["init","20", "30"]}' -p settlement`
thojest
2017-01-17 14:30
and it works
thojest
2017-01-17 14:39
i think that it has to do with my hfc version
thojest
2017-01-17 14:39
i remember having problems with this hfc interface before
thojest
2017-01-17 14:39
so im using hyperledger v0.6
thojest
2017-01-17 14:39
which hfc version do you recommend for this?
thojest
2017-01-17 14:48
yeah and tested in all available versions
thojest
2017-01-17 14:48
but i found something...
thojest
2017-01-17 14:49
although im not using bluemix
thojest
2017-01-17 14:50
this seems to be the same or at least a similar problem
thojest
2017-01-17 14:50
maybe some uber dev-pros can help me here
thojest
2017-01-17 15:06
so first question would be, when deploying via hfc sdk do i have to include the `certificatePath` ?
thojest
2017-01-17 15:07
when security is turned off
thojest
2017-01-17 15:31
i think not

thojest
2017-01-17 16:39
so new question
thojest
2017-01-17 16:39
which hfc version do you recommend for hyperledger v0.6 ?
thojest
2017-01-17 16:58
again question: when using hfc sdk for chaincode deployment i have the impression that it does not recognize my GOPATH
thojest
2017-01-17 16:59
however using `echo $GOPATH` shows me that it is set
thojest
2017-01-17 16:59
where do i have to set the GOPATH correctly for hfc sdk deploy chaincode to work?
thojest
2017-01-17 17:19
i think the problem is deployin chaincode in NON-dev mode using the hfc sdk
garisingh
2017-01-17 17:32
@thojest - definitely use the latest version of hfc available via npm - I think it's v0.6.5
garisingh
2017-01-17 17:35
it should recognize $GOPATH if its set. You can try doing `DEBUG=hfc node [your_app.js]`
garisingh
2017-01-17 17:36
you can of course always just print the output of `process.env['GOPATH']` as well in your Node program which is using the SDK
thojest
2017-01-17 17:42

thojest

ok found something that explains it
thojest
2017-01-17 17:59
so what is the reason behind it ?
cbf
2017-01-17 18:13
@thojest well, it is a long story;-)
cbf
2017-01-17 18:14
it has to do with the lifecycle of the creation for the chaincode's docker image
cbf
2017-01-17 18:15
if you deploy via the cli, then the binary has that context (the chaincode shim package in particular
cbf
2017-01-17 18:16
when you deploy with the sdk or REST API, then you need to ship all the bits
cbf
2017-01-17 18:17
frankly I would have preferred a model where we build a docker image and just point to a published docker registry entry
cbf
2017-01-17 18:18
of course then you need to deal with platform and architecture specific issues
thojest
2017-01-17 18:19
thx for the nice explanation
yashgt
2017-01-17 18:51
@muralisr to your response on whether SDK validates the endorsements, does it mean that the transaction is considered Endorsed if and only if "enough" number of endorsements are received *and* all the received endorsements match? If so the description in the 1.0 proposal should be updated to include both the criteria.

I was running a fabric network locally using docker. I was attempting to delete my blockchain for testing purposes by navigating to the validating peer file system by using a command like docker exec -it substitute_container_name bash and deleting the /var/hyperledger/production directory. I initially deleted /var/hyperledger/production/db but I was still seeing my blockchain so deleted the /var/hyperledger/production directory. Now I can't startup my network, memberservices container starts up by the fabric peer does not. I get the below error:

How do I fix this?
ghaskins
2017-01-18 03:13
@shaggy_kp I am not sure what is actually failing, but I suspect the persistence is caused by your composition
ghaskins
2017-01-18 03:13
try running "docker-compose down" (using any "-f" directives that are mirrorred from your "up")
ghaskins
2017-01-18 03:13
and then try again: that should start you fresh
ghaskins
2017-01-18 03:14
note that you are blowing away the old containers though
ghaskins
2017-01-18 03:14
@cbf do we have an archive of any of the old GH issues?
ghaskins
2017-01-18 03:15
I had written an issue (I believe it predated the JIRA migration)
shaggy_kp
2017-01-18 03:26
@ghaskins I tried running "docker-compose down" but this resulted in the same error.
ghaskins
2017-01-18 03:27
are you specifying any volume mounts in your composition?
shaggy_kp

I don't think so. Actually, the errors are not exactly the same. Below is what I get now:

The hyperledger/fabric-peer is latest
shaggy_kp
2017-01-18 03:32
but the hyperledger I cloned is v0.6
shaggy_kp
2017-01-18 03:59
I was able to at least get my network up and running again by changing the ports listing in my docker-compose.yml. It was listing 7050, 7051, and 7053. I changed it to 7051,7052,7053.
shaggy_kp
2017-01-18 04:00
I don't understand why listing port 7050 doesn't work

hey guys i need a bit help with the govendor
thojest
2017-01-18 09:16
in the documentation i have found that one has to vendor the dependencies in order to deploy chaincode using hfc sdk
thojest
2017-01-18 09:16
` go get -u http://github.com/kardianos/govendor
cd $GOPATH/src/github.com/chaincode_example02
govendor init
govendor fetch http://github.com/hyperledger/fabric`
thojest
2017-01-18 09:16
might someone explain what these lines do?
thojest
2017-01-18 09:17
so the first updates govendor package correct? doesnt matter in which directory i am?!
thojest
2017-01-18 09:17
what exactly does `govendor init` and `govendor fetch`
thojest
2017-01-18 09:18
so if you have no idea the documentation on github is far too less
thojest
2017-01-18 09:42
so i think i have an idea now
thojest
2017-01-18 09:43
so what i have now basically done is `govendor init`
thojest
2017-01-18 09:43
and `govendor add +external`
thojest
2017-01-18 09:46
thus, entering `govendor list` shows that all dependencies are present
vadim
2017-01-18 09:46
aren’t vendor dependencies already present in the repository?
thojest
2017-01-18 09:51
hm what do you mean?
vadim
2017-01-18 09:51
what are you trying to do?
thojest
2017-01-18 09:52
im trying to deploy my chaincode in non-dev mode using the hfc sdk
thojest
2017-01-18 09:53
i was told that i had to vendor dependencies which i think i have done now
vadim
2017-01-18 09:53
you can build chaincode without fetching any vendor dependencies because they are already in the repository
vadim
2017-01-18 09:53
you don’t need govendor, just make sure your fabric is in the gopath
thojest
2017-01-18 09:53
i think that is not true
vadim
2017-01-18 09:53
I just send you the link
thojest
2017-01-18 09:54
when you want to deploy via hfc sdk then you have to include the dependencies on shim package and so on
thojest
2017-01-18 09:54
this is not true for deploying via CLI
thojest
2017-01-18 09:54
in fact i can deploy my chaincode easily using command line
thojest
2017-01-18 09:54
but when deploying via hfc you have to vendor
vadim
2017-01-18 09:54
ok if you say so
thojest
2017-01-18 09:55
anyway i get an error message now :smile:
thojest
2017-01-18 09:59
and i think i somehow run into trouble with the directory structure
garisingh
2017-01-18 10:15
@thojest - take a look here - https://github.com/IBM-Blockchain/SDK-Demo/tree/master/src/chaincode
garisingh
2017-01-18 10:15
this is a demo which shows deploying chaincode in net mode using the NodeSDK
garisingh
2017-01-18 10:15
the link I sent shows how to set up your chaincode structure
thojest
2017-01-18 10:19
@garisingh thx thats exactly what im looking at
thojest
2017-01-18 10:19
so i identified the problem i think
thojest
2017-01-18 10:20
the docker container in which the chaincode is deployed
thojest
2017-01-18 10:22
runs the following command during the deploy process
thojest
2017-01-18 10:22
`/bin/sh -c go install build-chaincode && cp src/build-chaincode/vendor/github.com/hyperledger/fabric/peer/core.yaml $GOPATH/bin && mv $GOPATH/bin/build-chaincode $GOPATH/bin/25e6a48b86db7565f6c2d14422144bb4fcaf92ec4c`
thojest
2017-01-18 10:23
the problem i get is `cp: cannot stat 'src/build-chaincode/vendor/github.com/hyperledger/fabric/peer/core.yaml': No such file or directory`
meraki
2017-01-18 10:23
has joined #fabric
thojest
2017-01-18 10:23
so the problem i think is that `go install build-chaincode`
thojest
2017-01-18 10:23
does not create the `../peer` folder
thojest
2017-01-18 10:24
and this is true as i have logged into the container `docker run -it ....`
thojest
2017-01-18 10:25
and run the commands manually
thojest
2017-01-18 10:25
there is no peer directory
thojest
2017-01-18 10:27
is it possible that this has to do with my hfc sdk version im using? as im using the newest version which is @0.6.5 i think but i use hyperledger fabric v0.6

Hello everyone, I have tried to do a production Hyperledger network, however I can not have more than four peers. When I run, for example, five peers, the peers runs. However, when I deploy a chaincode, only four peers has the copy of the chaincode, so I think that the fifth peer does not see the others peer. Could anyone help me? Thx
yacovm
2017-01-18 10:34
you're running v0.6 right? @maritere ?
maritere
2017-01-18 10:36
yeah
thojest
2017-01-18 10:37
i think the problem is with `govendor add +external`
thojest
2017-01-18 10:37
so if i run `govendor list`
thojest
2017-01-18 10:38
should it list the fabric/peer folder ?
yacovm
2017-01-18 10:39

Thanks very much! I'm going to try again changing it!! :grin:
yacovm
2017-01-18 10:40
Thank me only if it works
thojest
2017-01-18 10:47
if im running `govendor fetch http://github.com/hyperledger/fabric` it does exactly nothing

trying to deploy my chaincode via hfc sdk i get the following error

2017-01-18 13:54
transport: http2Server.HandleStreams failed to receive the preface from client: read tcp 127.0.0.1:7051->127.0.0.1:42608: read: connection reset by peer
thojest
2017-01-18 13:54
what does it mean?
umasuthan
2017-01-18 14:01
@garisingh, Thank you so much for the pointer
thojest
2017-01-18 14:03
the first ip address+ port is my peer node
thojest
2017-01-18 14:03
but what is the second?
thojest
2017-01-18 14:24
@jzhang i have read somewhere that you have been involved in fixing this. im trying to deploy my chaincode via hfc sdk i get the following error
transport: http2Server.HandleStreams failed to receive the preface from client: read tcp 127.0.0.1:7051->127.0.0.1:42608: read: connection reset by peer
im using hyperledger v0.6 and this is independent of the version of hfc im using (happens for all v 0.6.x). do you have an idea what the problem is?
jzhang
2017-01-18 14:33
@thojest the message is a bit different now but I believe it basically says the peer node (:7051) is talking to newly instantiated container instance for executing chaincode (:42608), but the connection has been severed because the container instance was done executing chaincode. this should be harmless (unless this is happening in a different context, which is difficult to tell without further details)
jzhang
2017-01-18 14:34
in the end was your transaction successfully processed?
thojest
2017-01-18 14:37
@jzhang the problem is that the docker container for the chaincode seems missing a desired core.yaml file. this is the complete error log
2017/01/18 15:15:28 transport: http2Server.HandleStreams failed to receive the preface from client: read tcp 127.0.0.1:7051->127.0.0.1:42742: read: connection reset by peer

jzhang
2017-01-18 14:42
the first thing that comes to mind is how you obtained the “fabric-baseimage” docker image
thojest
2017-01-18 14:43
@jzhang i git clonde v0.6 hyperledger and built it myself
jzhang
2017-01-18 14:43
ok, that should be fine then. the next one is whether you have populated a “vendor” folder in the chaincode directory that contains the fabric source tree
thojest
2017-01-18 14:44
@jzhang note that i can deploy my chaincode without using hfc sdk
thojest
2017-01-18 14:44
@jzhang i also think that i have done something wrong using govendor
jzhang
2017-01-18 14:44
yes and creating the “vendor” folder is specific to deploying from hfc, and a step many developers miss
jzhang
2017-01-18 14:45
check to make sure it’s there alongside your chaincode go file
thojest
2017-01-18 14:45
@jzhang what ive done is `govendor init` and `govendor add +external`
thojest
2017-01-18 14:45
@jzhang then `go build`
jzhang
2017-01-18 14:45
can you `ls` your chaincode folder and the `vendor` folder?

can you double check the file `vendor/github.com/hyperledger/fabric/peer/core.yaml is there?
thojest
2017-01-18 14:48
when i do `govendor list`
thojest
2017-01-18 14:48
thats exactly what i suspect
thojest
2017-01-18 14:48
it isnt there
thojest
2017-01-18 14:49
as it is not in `govendor list` depndencies
jzhang
2017-01-18 14:50
@ratnakar may have a suggestion here on how to properly populate the `vendor` folder. i think git clone the fabric repo under the `vendor/github.com/hyperledger` directory should fix it
jzhang
2017-01-18 14:50
although i don’t know if there’s a better way to do this using govendor only
thojest
2017-01-18 14:50
thanks alot now i know what is the problem :slightly_smiling_face:
thojest
2017-01-18 14:51
@jzhang last qustion: using `govendor fetch http://github.com/hyperledger/fabric` does nothing
thojest
2017-01-18 14:51
do you have an idea why
thojest
2017-01-18 14:52
this is the reason i had to `govendor add +external` instead of fetching from net
jzhang
2017-01-18 14:55
not sure, haven’t used govendor that much :wink:
thojest
2017-01-18 14:56

Is there anybody who got the asset_management example to work?

2017-01-18 15:08
@jzhang @thojest I never succeeded with `govendor` , hence I always created a folder `mkdir -p vendor/github.com/hyperledger` and clone of V0.6 based fabric code `git clone -b v0.6 --single-branch https://github.com/hyperledger/fabric.git`
thojest
2017-01-18 15:09
@ratnakar does this mean that i basically just have to copy the whole fabric folder into vendor ?
ratnakar
2017-01-18 15:16
yes that is right @thojest
thojest
2017-01-18 15:17
@ratnakar but i do not have to built it again?!
ratnakar
2017-01-18 15:17
No you don't need to build
thojest
2017-01-18 15:18
@ratnakar this is nice.... took me 2 days :smile:
ratnakar
2017-01-18 15:20
Here is a sample program if you want to use non-vagrnt environment (using Fabric V0.6 based images ) https://github.com/ratnakar-asara/hello-blockchain
thojest
2017-01-18 15:22
@ratnakar thx alot im not using vagrant i built fabric v0.6 myself on bare metal ubuntu......... and now its finally working. i have deployed my first chaincode using a nodejs app HEUREKA!
kamo
2017-01-18 16:06
@thojest can you please just describe in short how you built your own peer and membersrvc images? would be very helpful
thojest
2017-01-18 16:17
@kamo well basically you just have to git clone hyperledger/fabric on github (i cloned v0.6) and then you have to change into the fabric directory
thojest
2017-01-18 16:17
there run `sudo make`
thojest
2017-01-18 16:18
however you have to install a lot of things before like go, docker, pip, nodejs, npm, rocksdb, ......................
kamo
2017-01-18 16:19
I installed all of this stuff, but im under OSX :confused:
thojest
2017-01-18 16:19
it took me one or two days to get this working
thojest
2017-01-18 16:19
@kamo i have no experience with osx but i think you then just need the right compiler
kamo
2017-01-18 16:20
okay thanks !
madhava
2017-01-18 16:20
@thojest have initially done the same setup but when i deploy chain code it never created a docker image
thojest
2017-01-18 16:21
@madhava what exactly goes wrong?
madhava
2017-01-18 16:23
have exactly installed fabric as mentioned like above on Ubuntu and was able to deploy and invoke chain code by running below cmds
madhava
2017-01-18 16:23
CORE_CHAINCODE_ID_NAME=mycc CORE_PEER_ADDRESS=172.17.0.3:7051 ./chaincode_example02
CORE_PEER_ADDRESS=172.17.0.3:7051 ./peer chaincode deploy -n mycc -c '{"Args": ["init", "a","100", "b", "200"]}'
CORE_PEER_ADDRESS=172.17.0.3:7051 ./peer chaincode invoke -l golang -n mycc -c '{"Args": ["invoke", "a", "b", "10"]}'
madhava
2017-01-18 16:24
but was not able to call the chain code through Rest API because above cmds never returned chaincodeID
thojest
2017-01-18 16:26
@madhava well when you deployed that way i think you have deployed in developer mode
thojest
2017-01-18 16:26
so you started your peer with `peer node start --peer-chaincodedev`
thojest
2017-01-18 16:27
this way the chaincode is not run in a docker container
thojest
2017-01-18 16:27
im not sure if you then get a chaincodeId ?
madhava
2017-01-18 16:28
this is the docker compose yaml file which i used to start peer and memberserv

yes!
madhava
2017-01-18 16:29
yes its in development mode only
thojest
2017-01-18 16:29
@madhava have you tried deploying in non-dev mode?
madhava
2017-01-18 16:30
not yet
madhava
2017-01-18 16:32
@thojest you want me to change it to network mode, i am running only on one node
thojest
2017-01-18 16:35
@madhava well i dont know if that helps
madhava
2017-01-18 16:37
ok, @thojest when you deploy are you getting ChaincodeID through this setup
madhava
2017-01-18 16:37
i registered the chain code

is that what you want?
madhava
2017-01-18 16:39
yes
thojest
2017-01-18 16:39
you can now invoke using
thojest
2017-01-18 16:40
`peer chaincode invoke -n THISLARGEHASH -c '{"Args": ......}'`
thojest
2017-01-18 16:41
then start your peer node in non-dev mode and deploy like i have written
madhava
2017-01-18 16:41
yes i did the same
madhava
2017-01-18 16:41
but it will never give the chain code id
madhava
2017-01-18 16:41
CORE_PEER_ADDRESS=172.17.0.3:7051 ./peer chaincode deploy -n mycc -c '{"Args": ["init", "a","100", "b", "200"]}'
thojest
2017-01-18 16:41
you have to deploy with -p
thojest
2017-01-18 16:42
instead of -n
thojest
2017-01-18 16:42
-p and then specifiy the directory of your chaincode RELATIVE to $GOPATH/src
thojest
2017-01-18 16:42
which is settlement in my case
madhava
2017-01-18 16:44
ok let me try
madhava
2017-01-18 16:49
@thojest when i tried with relative path its says path doesn't exist

madhava
2017-01-18 16:50
i can see files
thojest
2017-01-18 16:50
yeah u misunderstood me i think
thojest
2017-01-18 16:51
madhava
2017-01-18 16:52
does it will take the chain code from gitgub or from my local, just for my clarification
thojest
2017-01-18 16:52
local
madhava
2017-01-18 16:56
ok, it worked :slightly_smiling_face: thank you @thojest , can you also please help with invoke statement, currently am using below statement
madhava
2017-01-18 16:56
CORE_PEER_ADDRESS=172.17.0.3:7051 ./peer chaincode invoke -l golang -n mycc -c '{"Args": ["invoke", "a", "b", "10"]}'
madhava
2017-01-18 16:56
now have chaincodeID will above statement will change?
thojest
2017-01-18 16:56
just exchange mycc with the chaincodeid
madhava
2017-01-18 16:57
ok
thojest
2017-01-18 16:57
and i think you do not have to enter -l golang as this is default
madhava
2017-01-18 17:00
ok invoke worked perfectly but when i run query its giving me some error
madhava
2017-01-18 17:01

thojest
2017-01-18 17:02
hmm maybe try another name for your `query` in Args
thojest
2017-01-18 17:02
this is the function which is mapped to Query using the shim interface
thojest
2017-01-18 17:02
maybe this is a problem but i dont know
madhava
2017-01-18 17:04
ok but actually am using sample chain code 02 which is present in git hub only
thojest
2017-01-18 17:06
hmm then this shouldnt be a problem
thojest
2017-01-18 17:07
let me try it myself
thojest
2017-01-18 17:14
@madhava hmm it works in my case
thojest
2017-01-18 17:14
peer chaincode query -n c9982b613cbb9031dec8657ee3109219a8a8bd2bc96f70c3786de605c92563b8cc9d84e0110fc16e548913bf13397698a8b9171556f20bc605aa8947bd0ddfce -c '{"Args": ["query", "Bob"]}'

thojest
2017-01-18 17:15
i think you have pasted the wrong chaincode id
thojest
2017-01-18 17:16
note that it changes if slightly change your deployment initialization or the chaincode itsself
thojest
2017-01-18 17:16
i was able to reproduce your error using a wrong chaincodeID

There is also a #fabric-consensus-dev channel, but I think that a very good JIRA item that may give you very specific detail (and other references) is https://jira.hyperledger.org/browse/FAB-37
jonathanlevi
2017-01-18 17:25
Since you want the “cutting edge” / latest. Also, just quickly, the `master` branch of fabric is where the “new” stuff is being developed.
jonathanlevi
2017-01-18 17:26
There are dev-previews (with snapshots, that are considered more stable), but in general, that branch is considered the main, under-development one.

Hello everyone
ingcr3at1on
2017-01-18 21:49
so I gather the membersvc has been moved into cop is there any documentation setup for replacing the membersvc docker image with a cop instance for non-vagrant linux setups? (referring to this setup guide: http://hyperledger-fabric.readthedocs.io/en/latest/Setup/Chaincode-setup/#option-3-docker-toolbox)
ingcr3at1on
2017-01-18 21:50
(possibly a better question for #fabric-cop ?)
garisingh
2017-01-18 21:54
@ingcr3at1on - quick answer is the fabric-cop cannot replace membersvc when using v0.6
ingcr3at1on
2017-01-18 21:56
hmm, fair enough; maybe a better question would be how can I create my own membersvc docker image so that I don't have to edit the membersvc.yaml file inside the docker container after it starts if I want to modify that configuration lol
ingcr3at1on
2017-01-18 21:56
I probably missed something when I was looking through git
ingcr3at1on
2017-01-18 21:57
or would it be more prudent for me to switch to a newer version of fabric and use cop lol
ingcr3at1on
2017-01-18 22:05
hmm, nvm seems I missed some documentation for setting up a network, thanks @garisingh
ghaskins
2017-01-18 22:18
@ingcr3at1on: there are a few options
ingcr3at1on
2017-01-18 22:18
I'm all ears :smile:
ingcr3at1on
2017-01-18 22:18
(assuming you don't mind sharing)
ghaskins
2017-01-18 22:18
You can always override individual parameters with envvars, I assume you already know that
ghaskins
2017-01-18 22:18
(Sorry, mobile and thus slow)
ingcr3at1on
2017-01-18 22:18
no worries
ingcr3at1on
2017-01-18 22:19
I hadn't actually thought to try that yet (now I feel stupid cause we do that with our docker containers at my job)
ghaskins
2017-01-18 22:19
You can also derive a new docker container with "FROM hyperledger..."
ghaskins
2017-01-18 22:19
You can volume mount a new yaml
ghaskins
2017-01-18 22:20
E.g. "docker run -v path/to/replacement/membersvcs.yaml:/etc/hyperledger/fabric ..."
ghaskins
2017-01-18 22:20
Check paths, that is from memory
ghaskins
2017-01-18 22:21
And lastly, you can hack fabric.git and then "make membersvcs-image"
ghaskins
2017-01-18 22:22
That's all I can think of
ghaskins
2017-01-18 22:22
But those are a few options
ingcr3at1on
2017-01-18 22:23
yeah that last option was what I was looking into but I hadn't actually thought of overriding the yaml for some reason lol
ingcr3at1on
2017-01-18 22:23
thanks

@ghaskins regarding the third possibility, is it possible to call “make membersrvc-image” on OS X ?
ghaskins
2017-01-18 23:16
We support building on OS X in master, but membersvc moved to fabric-cop

kamo
2017-01-18 23:35
yes, but i want to work with v0.6 until master is stable, is there a possibility for building own docker images on OSX?
ghaskins
2017-01-19 02:29
I did quite a bit of work on master to get that all working
ghaskins
2017-01-19 02:29
so, I doubt you could just take the v0.6.1-preview and build it
ghaskins
2017-01-19 02:29
that said, if you are adventurous, I'm sure you could backport the patches
ghaskins
2017-01-19 02:30
ill warn you though: I dont think it will be trivial. I recall there were not only build system changes, but also bug fixes
ghaskins
2017-01-19 02:31
for instance, AUTODETECT ends up being critical on OSX b/c of the way the docker-for-mac treats 0.0.0.0 addressing
ghaskins
2017-01-19 02:33
but you can also always use vagrant
ghaskins
2017-01-19 02:33
that is supported on OSX for v0.6

can fabric run in a real machine instead of docker container? I mean docker is only used for chaincode.

hi everyone, I have a question concerning the application of blockchain in banks. Lets say you have some asset e.g. a bond and you want model the cashflows of this bond on a blockchain. How would you do that? Can you just use integers written into the blockchain for the cash? Or do you use a token? How do you connect the blockchain to the bank's core system? Are there any materials about this?
yacovm

question: when i deploy a chaincode on a peer node this opens a docker container where the chaincode is run
thojest
2017-01-19 10:20
correct?!
thojest
2017-01-19 10:21
is the chaincode written somehow into the blockchain or at least a hash?
thojest
2017-01-19 10:26
so now i have a network of peers
thojest
2017-01-19 10:26
and i deploy the chaincode to one peer
thojest
2017-01-19 10:26
how do the others know of this chaincode? does every peer node spin up a docker container on its own?
thojest
2017-01-19 10:26
or do they get the address of the dockercontainer where the chaincode was deployed?
garisingh
2017-01-19 10:36
@thojest -
1) Yes - chaincode is run in a Docker container and the peer process communicates with the chaincode in the container over GRPC
2) In v0.6, each validating peer will spin up its own instance of the chaincode in a Docker container. In v1, each endorser will spin up its own copy of the chaincode as well
3) The bytes of the chaincode (which are used to create / spin-up the Docker container are distributed to the peers as part of the deploy transaction. In v0.6, recall that all validating peers participate in every transaction - so the transactions are broadcast to all validating peers as part of the consensus / transaction flow. The bytes of the chaincode are included in the payload of the transaction (and yes - they do get persisted to the ledger as well). In v1, transactions are broadcast via the ordering service - so if you are part of any given channel on which a deploy was run, you'll receive the bytes of the chaincode in a transaction (in a block) broadcast by the ordering service

Can chaincode run at a set time? Thanks.

@subaru365 - nope. you'd have to write a cron process outside of fabric to invoke the chaincode at a specified time

what registerChainCodeEvent exactly does?

2017-01-19 13:49
//Listen to custom events
var regid = eh.registerChaincodeEvent(chaincodeID, "evtsender", function(event) {
console.log(util.format("Custom event received, payload: %j\n", event.payload.toString()));
eh.unregisterChaincodeEvent(regid);
});
thojest
2017-01-19 13:59
can I emit now the event regid ?

ghaskins

IIRC its the same pattern
harrijk
2017-01-19 18:25
@ghaskins i changed "/" to "@" in the sed commands and it appears to work just fine.... e.g., sed -e 's@_DOCKER_BASE_@$(DOCKER_BASE)@g' \
harrijk
2017-01-19 18:25
However, I then got this error later on in the build... maybe I don't have the right repo and patch (I did apply 4107 patch on top of fabric-baseimage repo)...

i refactored how the images were built, so im guessing wget made its way into the x86/ubuntu path but not s390/debian
ghaskins

ty for investigating
ghaskins
2017-01-19 18:28
ill refactor the sed expressions and try again

I think I prefer 's|||' over 's@@@'
ghaskins
2017-01-19 18:29
you ok with that?

2017-01-19 18:29
Looks like we need wget for the Debian s390x image

@garisingh is there an easy way to export the world state in 0.6x nodes?

depends on your definition of "easy" :wink:

we don't provide any capability to do it

2017-01-19 21:38
of course it's all in rocksdb and so you could kill the peer process and write your own application which dumps the data from rocksdb

Hi, question related to Chaincode.
We know that the Chaincode gets deployed in the docker images (with acting as sandbox).
Say my dockers went down, say crashed. So how about resuming my Chaincodes? I can see that the docker images are still there, containers are in stopped status. When I issue docker-compose start or restart, that would bring up the other nodes. But how about the Chaincode containers?? How about the ledger which was there? Will that be intact?

garisingh
2017-01-20 08:34
@ashishkel - the peer will bring back up the chaincode when needed (i.e. the next time chaincode is invoked / queried). Now you of course should not rely on any non-ledger state being preserved (meaning don't have chaincode which keeps state in memory or attempts to write to the filesystem). What technically happens is that when the peer detects that chaincode is not running, it will first delete any existing container instance for that chaincode and then create a new container instance from the image (if it can't find an existing image it can then get the chaincode bytes from the ledger and build both the image and create/start a container instance)
Ledger data / state snapshot are both still intact

@eugenluft the latest set of published images is v0.6, yes. We haven't released v1.0 just yet. Possibly in the next couple of weeks we should have v1.0-alpha images published.

you might want to actually delete the exiting containers and run your compose script again

no, what you want to do is pull hyperledger/fabric-baseimage:x86_64-0.2.0 and tag it as hyperledger/fabric-baseimage:latest then run the compose (the one I linked will work)

I´m a little bit confused about the used version and endorsing feature. I have fetched the latest fabric code and every time i´m trying to deploy the code i see an error message `Error: Error endorsing chaincode: rpc error: code = 12 desc = unknown service protos.Endorser`. Endorser is a 1.0 feature and the latest tagged version is 0.6, right?

the node is running in non-dev mode (only `peer node start`)
eugenluft
2017-01-20 12:49
I´m not sure but could it be that i need to pass some parameters, eg. the IP address of the node?
eugenluft

Because i can not see any error message on the node itself.

I am running a chaincode using node sdk on the 4 node setup in bluemix for the last 3 days. My chaincode is stable and ran without issues on docker. I noticed a couple of issue while running on bluemix.
1. I had to redeploy the same code 10 out of 25 times before proceeding with invoke and query (about 40%). The chaincodeID remained same. I had to force deploycode.
2. After few minutes of idle time, the connection is reset by peer and it crashes the nodejs app. Not sure where to catch this error to avoid my nodejs app crash.

garisingh
2017-01-20 15:43
0.6.1-preview although we should have be getting a build of the v1.0 architecture out hopefully by the end of the month. But if you just want to start getting used to the chaincode model, 0-6-1-preview should be a good fit for you for now

are queries basically gone now?
ghaskins
2017-01-21 12:43
or is there still a notion of a certain mode in which invokes are RO?
silliman
2017-01-21 14:05
@ghaskins in v1.0 explicit queries are no longer necessary. For a query you would send a TransactionProposal, and within the TransactionProposalResponse you will get your ReadSet. If you're satisfied with the results, you're done....since you don't want to update anything, you just call it a day and you don't need to send an endorsement to the Orderer. I suppose for purposes of a Query you could even invoke a function that might even perform updates, since, if you don't send along the Endorsement to the orderer, those changes won't ever be committed.
ghaskins
2017-01-21 14:06
@silliman ty, this makes sense
arnaud
2017-01-21 14:12
@silliman although I understand the logic the resulting API isn't as intuitive
garisingh
2017-01-21 14:12
@ghaskins - it also allows you to do some strong reads as well. but I am pretty sure that we also want to add pass-thru queries on the peer itself as well
arnaud
2017-01-21 14:12
we're going to have to keep explaining that to query you make a proposal you never commit
ghaskins
2017-01-21 14:13
that all makes sense, I was mostly trying to plan how I would update the chaintool schema/code-generator
ghaskins
2017-01-21 14:14
in v0.6 and earlier, transactions/queries were first class in the grammar
garisingh
2017-01-21 14:14
I'd wait a bit on that but I hear ya :wink:
ghaskins
2017-01-21 14:14
wait a bit on what?
arnaud
2017-01-21 14:14
I wonder whether you shouldn't have query as a synonym, just to make the interface more user friendly
garisingh
2017-01-21 14:14
until everything is finalized from an endorser API / chaincode perspective
garisingh
2017-01-21 14:15
although I think the chaincode should stay mostly the same t this point
silliman
2017-01-21 14:15
@arnaud well, when you do an Invoke you have to submit a function name as well so you can just code function names that make it evident it's a query ... just think of invoke as invoking a transaction, some will be read-only, some will perform updates.... just my 2 cents
ghaskins
2017-01-21 14:15
@arnaud I am unclear if you are advocating to keep or remove the query notion in the chaintool grammar?
arnaud
2017-01-21 14:16
I'm advocating to add it back :slightly_smiling_face:

2017-01-21 14:16

Im referring specifically to this: https://github.com/hyperledger/fabric-chaintool#definition

2017-01-21 14:17
in the code I am working on now, I am collapsing transactions/queries into one "functions" block
arnaud
2017-01-21 14:18
I see
ghaskins
2017-01-21 14:19
@ghaskins uploaded a file: https://hyperledgerproject.slack.com/files/ghaskins/F3UJ58AE7/-.txt and commented: It would look like this now
ghaskins
2017-01-21 14:19
from a function-dispatch perspective, it probably doesnt make sense to delineate them in the grammar any more
arnaud
2017-01-21 14:23
I agree that at this level this actually simplifies the interface
muralisr
2017-01-21 15:44
To add to the discussion (and to @silliman note) … (1) note that we could potentially send a proposal to multiple peers AND have endorserments from them to make sure they all say the same thing. (2) the “query” CLI was just a convenience method as a synonym for “the invoke that won’t be sent as transaction” … ie, the peer itself doesn’t care what the SDK / CLI / User does with it
yacovm
2017-01-21 15:55
sending a proposal to multiple peers sounds good but how do you know about them?
silliman
2017-01-21 16:14
@yacovm as of two days ago in discussions in #fabric-dev @muralisr stated that the CLI does not support a single request being sent to multiple endorsers, so at this time you'd have to send multiple requests to each endorser that interests you. @harrisob then said that the node SDK does support multiple endorsers so perhaps he would be willing to share more details. As to how the client or SDK would know about them, I assume this would be a configuration exercise.
muralisr
2017-01-21 16:21
right, `sending a proposal to multiple peers sounds good but how do you know about them?` we have to enhace the CLI to take a list of peers… I believe there’s already support in node SDK for this but do double-check @yacovm
muralisr
2017-01-21 16:23
(for some reason I keep hitting enter before a name is completed today… wonder if theres some subtle change in slack interface my muscle memory is tripping upon)
yacovm
2017-01-21 16:25
But does this approach scale? The user needs to remember which peers are in which channel
muralisr
2017-01-21 16:33
well, its probably a combination of user/application … the “carasset” application knows to send a “new car “ proposal to DMV and Insurance peers
muralisr
2017-01-21 16:34
but yes, in other applications “who are the peers to send to ?” may not be easy/obvious

from http://hyperledger-fabric.readthedocs.io/en/v0.6/starter/fabric-starter-kit/#further-exploration
> The setup uses Docker to provide a controlled environment with all the necessary Hyperledger fabric components to support a Node.js application built with the fabric’s Node.js SDK, and chaincode written in Go.
1. what is the difference between the application and the chain code?
2. is it possible to get the same functionality of both the node.js app and the go chaincode using the REST API for the fabric network?
silliman
2017-01-21 21:36
@bcq for #1, in this case, the application is your front-end logic, typically, but not necessarily, including a GUI, that will call the APIs provided by the Node.js SDK. In turn, the implementation of the SDK APIs will deploy or invoke chaincode, also known as smart contracts, which is where CRUD (Create/Read/Update/Delete) operations on the state takes place, and the 'CUD' part of CRUD, in the "happy path", causes immutable transactions to be saved on the blockchain.
for #2, in Fabric v0.6, for the most part, the REST API can mimic the SDK calls, but not exactly, e.g. registering and enrolling users behaves differently when done through the SDK than when done through the REST API. Furthermore, the REST API is deprecated for Fabric v1.0. In v1.0 the best practice programming model is to use one of the SDKs. In either case, whether you use SDK calls or REST API calls that deal with chaincode, you are deploying or invoking the chaincode from them, you are not replacing chaincode with them.

hey guys im having a problem using hfc sdk as an interface between my app and chaincode. im using hyperledger v0.6. The thing is, that I am unable to get errors with `invokeTx.on('error', function(results) {....})`

where `var invokeTx = userObj.invoke(invokeRequest)`

What are some possible causes for a chaincode error like:
`Chaincode handler FSM cannot handle message (RANGE_QUERY_STATE) with payload size (18) while in state: ready`?
This is on the 0.6.1-preview peer in the hyperledger/fabric-peer docker image, using --peer-chaincodedev
schristie

the deploy transaction seemed to work just fine, as do most invoke transactions; it's just the queries that fail
silliman
2017-01-23 16:31
@schristie this *could* be your problem: I've seen this where people are trying to use the v0.6 branch of the code and then are following the instructions in the v0.6 branch of the documentation, but....get twisted up because there are a couple spots in this doc where it has a wget (for the chaincode) and a git clone (for getting the fabric code available locally in order to build the chaincode) that refer to *master*. The problem is, that *master* is now v1.0 code. So, they are running Docker images with v0.6 code but when they build the chaincode locally, it incorporates v1.0 code in into it. The solution is, in the *wget* and the *git clone*, change *master* to *v0.6* in the path name. I am being purposely vague as to where this documentation is, because if I've guessed correctly, you know what I'm referring to, but if I've guessed wrong, it's something else and I don't want to lead you on a wild goose chase. I hope this helps.

silliman
2017-01-23 16:58
@schristie Not that I'm aware of ... chaincode is expected to be able to migrate with minimal changes, but the underlying architecture of the fabric is quite different and so migration of the state data is not supported IIRC ... there are some demo apps that folks are working on migrating from 0.6 to 1.0 (e.g. car-lease-demo at https://github.com/IBM-Blockchain/car-lease-demo) so it's possible that someone may at some point produce a document on how to migrate chaincode from v0.6 to v1.0

vigneswaran.r
2017-01-24 05:32
Hello, is it possible to hide (part of the) transaction details from some of the validating peers (in Fabric v0.6)? Eg., when competitors are running peer nodes in a blockchain setup, they may not be willing to reveal all the data to every other node. Whether, Fabric is suitable for such usecases?
ibmamnt
2017-01-24 06:19
@vigneswaran.r Probably, the right answer is separate business network while using the same infrastructures. competitor may join to network (say BizA), but can not join to (say BizB). If a company want to hide the data, all transaction goes to BizB network.
vigneswaran.r
2017-01-24 06:40
@ibmamnt Ok. So, by "separate business network", do you mean running multiple instances of blockchain (BizA, BizB) on the same infrastructure, and some companies are registered on BizA and some on BizB?
vadim
2017-01-24 08:06
@vigneswaran.r you can also encrypt it before writing it to the blockchain
ibmamnt
2017-01-24 08:21
@vigneswaran.r I meant about it. This may be good to take a look (though it is currently under discussion).

@ibmamnt Ok, I will look into it. Thanks.
vadim
2017-01-24 08:29
@ibmamnt according to that document, orderers still see all transactions and confidentiality is only on a peer level
vigneswaran.r
2017-01-24 08:29
@vadim You're right, we can do encryption. However, if we consider a simple scenario where A wants to transfer B some amount X, then even if we encrypt X, in order to execute the transaction (and make appropriate changes to the world state), all the VPs have to decrypt X. So, there is no way to hide X from the peers.
vadim
2017-01-24 08:32
I guess I can quote the paragraph from that document above: “Note that the consensus service receives all transactions for all chains, so confidentiality is only pertaining to the Peers and not the Orderers. This is fine when the consensus service is made up of trusted parties and regulatory bodies in a permissioned network; that is, the transactions are visible to them as business requirements. On the other hand, if the application doesn’t want the Orderers to see the content of transactions, it should utilize other techniques to hide the sensitive data such as hash or encryption. The Consensus Service acts as a trusted party. "
vadim
2017-01-24 08:33
so probably, this is very use case specific and sometimes the encryption will also be needed
vigneswaran.r
2017-01-24 08:37
@vadim Yeah, encryption is anyway preferred/needed to hide details from the other users of the blockchain (or from anyone who can read the blockchain). However, hiding it from some validating peers (in Fabric v0.6) doesn't seem to be possible.
thojest
2017-01-24 08:37
@gvlax ahh ok. but why doesnt it work?
vadim
2017-01-24 08:38
well it is possible, they just won’t be able to look inside the encrypted data and process it
vigneswaran.r
2017-01-24 09:01
@vadim In my understanding, VPs execute the chaincode. Typically, a transfer function in a chaincode expects to deduct money from the source account and add it to the destination account and update the worldstate accordingly. In order to achieve this, the chaincode requires X value (amount to be transferred) in unencrypted form.
vigneswaran.r
2017-01-24 09:03
So, either the peer (platform) has to do the decryption, or the chaincode has to do the decryption. I couldn't find any way to give the decryption keys to the chaincode without the peer's knowledge..

general question: do non validating nodes broadcast transactions to validating nodes only, or every node in the network?
garisingh
2017-01-24 14:29
@nickmelis - I would not worry too much about non-validating nodes at this point given we no longer have the concept in the latest version of the fabric, but to answer your question NVPs are basically like "clients" and they broadcast to one validating peer which is then responsible for distributing the tx to all peers.
nickmelis
2017-01-24 14:30
@garisingh are you saying there won’t be any NVP anymore? Can you explain a bit more?

Hi everyone :slightly_smiling_face:
Quick question: as I understand Fabric does not prevent non-deterministic chaincode to be pushed. Are there ways to make sure that does not happen (formal proofs?) or would hidden non-deterministic code be patched by “forking”?
Thanks!
ghaskins
2017-01-24 15:02
baring bugs, non determinism would fail to reach consensus (with the exception of code that is just detministic enough to pass quorum thresholds)
schaeff
2017-01-24 15:05
Thanks, so what would you do in each case?
ghaskins
2017-01-24 15:26
well, in the new design, you would submit a request to N endorsers and they would presumably respond with a read-write-set proposal
ghaskins
2017-01-24 15:26
your client would see that the RWS doesnt match right there
ghaskins
2017-01-24 15:26
as far as how the orderer would respond if you tried to submit all the mismatched proposals, I am not sure

ghaskins
2017-01-24 16:38
historically (as in v0.6 and prior) it was centralized. It needs to be decentralized. I am not sure if this is captured in the v1.0 design or not

@schaeff I do not have a complete answer to your question but I can say with a fair degree of confidence that this will not be managed by membership service's replacement in v1.0, which is the fabric-ca component. In fact in v1.0 the fabric-ca is optional in that you can provide your own X.509 (and maybe other stuff in future) certs other ways (e.g. your own LDAP, your own favorite Certificate Authority).... fabric-ca just happens to be the "out-of-the-box" method to do this. This is in contrast to Fabric v0.6 where if you wanted to use security, you have to run membership services. Hope this helps a little bit.

ghaskins

so, as a sanity check: you should be able to do "nmap localhost -p7050-7054" and see the 7050 open if you do that

hi! can a chaincode deploy new chaincodes? I noted it can invoke other chaincodes with `shim.InvokeChaincode()`, but how to deploy one?
vadim
2017-01-25 11:37
you deploy a chaincode using standard methods, you get some long string in return, then you use that string to identify that chaincode in call to InvokeChaincode()
vadim
2017-01-25 11:39
something like stub.InvokeChaincode(otherChaincodeId, util.ToChaincodeArgs(”otherccfunc”, param1, param2))
vadim
2017-01-25 11:40
I think I misunderstood the question, sorry :slightly_smiling_face:
denisglotov
2017-01-25 11:47
thanks Vadim, I can deploy chaincodes manually. But I want my chaincode to deploy chaincodes for me.
vadim
2017-01-25 11:48
yes, I got it
vadim
2017-01-25 11:48
I think it might be hard if you need to sign the deployment transaction
vadim
2017-01-25 11:48
then your chaincode needs to have certificate with key
vadim
2017-01-25 11:49
so basically this certificate will be distributed across all nodes
denisglotov
2017-01-25 11:50
maybe without encryption?
vadim
2017-01-25 11:51
I think you can operate in this mode in v0.6, but I’m not sure this is possible in v1
denisglotov
2017-01-25 11:52
ok, will think, thank you
vadim
2017-01-25 11:53
but what use case would it be to deploy a chaincode from a chaincode?
denisglotov
2017-01-25 11:55
many use cases, with general idea: many smart contracts keep/manipulate their part of data, and one "root" contract to keep track of them all
vadim
2017-01-25 11:56
you think it won’t make sense to store that data in one contract instead?
denisglotov
2017-01-25 11:57
yes, an option, but then we will have 1 global smart contract.
denisglotov
2017-01-25 11:57
Probably nothing bad, but wanted to split the logic into smaller pieces
vadim
2017-01-25 11:58
well, technically, you can define you logic in classes in golang, and then just deploy one contract
vadim
2017-01-25 12:00
there might be a problem in case of multiple contracts when you, for example, want to update them. I don’t know whether some special updating mechanism is planned in Hyperledger, but if not, you need to deploy a new contract each time
vadim
2017-01-25 12:00
so if you have 100 contracts, you maybe need to deploy them 100 times
denisglotov
2017-01-25 12:01
I think it is a good point, thanks again. Just got used in Solidity (Etherium) that it allows to easily create sub-contracts.
vadim
2017-01-25 12:01
it does, yes, but there the problem with deploying x contracts instead of one is even more important, since it always costs a lot of gas
denisglotov
2017-01-25 12:03
permissioned blockchains don't waste gas :slightly_smiling_face:
vadim
2017-01-25 12:03
well yes, but still a lot of deploy transactions to handle
denisglotov
2017-01-25 12:04
you right, cannot find any downside of it now...
denisglotov
2017-01-25 12:08
btw, do you happen to know if `1.0` code preview available
vadim
2017-01-25 12:10
well I think they plan to release the images by the end of this month
vadim
2017-01-25 12:10
but if you want to try it now, you can just checkout the master branch from git and build it yourself
denisglotov

2017-01-25 16:01
what is the problem here?
thojest
2017-01-25 16:02
i pulled all images with `sudo make` 2 months ago

2017-01-25 16:02
now it isnt working anymore

i would be very hapy for an answer because im nearly getting mad since I have been working now for 3 weeks on this and i cannot run my app anymore
ghaskins

@thojest what are you seeing?
thojest
2017-01-25 16:28
@ghaskins it tells me that there is a problem with the latest tag
ghaskins

ghaskins

are you in vagrant? osx? something else?
thojest

ghaskins
2017-01-25 16:30
ok, the commands/errors?
thojest
2017-01-25 16:30
wait a second
thojest
2017-01-25 16:32
cannot reproduce the error message at the moment because i changed something in my docker folder `/var/lib/docker`
thojest
2017-01-25 16:32
the problem is i think however
thojest
2017-01-25 16:33
that there is no latest tag for all the docker files anymore
thojest
2017-01-25 16:33
and when you enter e.g. `docker pull ......`
thojest
2017-01-25 16:33
it tries automatically to pull the latest version
ghaskins
2017-01-25 16:37
so, generally speaking: "latest" tags are a synthetic artifact of the build
ghaskins
2017-01-25 16:38
can you run "make clean images" and post the output?

ghaskins
2017-01-25 17:05
well, clean will clean up the local state
ghaskins
2017-01-25 17:05
i suspect you were in some funk and that forced the build to rebuild eveything
ghaskins
2017-01-25 17:05
note that the peer binary is not compiled as part of "make images", that only does the docker container
ghaskins
2017-01-25 17:05
in v0.6, you can do "make peer"
ghaskins
2017-01-25 17:06
in master, you can still do "make peer" but you can also do "make native" to build all the native binaries, including peer
ghaskins
2017-01-25 17:06
(which includes orderer, etc)
thojest
2017-01-25 17:44
@ghaskins so what can i do now to reverse `sudo make clean `
ghaskins
2017-01-25 17:52
take a look at the header for ./Makefile
ghaskins
2017-01-25 17:52
theres a number of targets available, depending on what you want
ghaskins
2017-01-25 17:52
from what you described, i think "make peer images" would do it

2017-01-25 18:03
is it possible to get all the docker images without gitcloning the fabric source code and running `sudo make images`
ghaskins
2017-01-25 18:20
not fully, at least not yet
ghaskins
2017-01-25 18:20
we pushed v0.6 images to dockerhub, but its not really what I would call "turnkey"
ghaskins
2017-01-25 18:20
we will be fixing this in 1.0
ghaskins
2017-01-25 18:21
there are steps you could do to work with the dockerhub images without building from code, but it would take a few extraneous steps aside from the usual suspects "docker pull/run"

Is it possible to override the peer configuration `chaincode.car` using environment variables (for fabric v0.6.1)? I would have guessed `CORE_CHAINCODE_CAR= FROM ...` would do the trick but it doesn't appear to be working.
bmatsuo

omg.. probably because it would be `CORE_CHAINCODE_CAR_DOCKERFILE=FROM ...`. Of course I don't realize that until seconds after I sent that last message.

Hi, I'm trying to understand the fabric-boilerplate example and I am not understanding what is the need of keyvalstore. I'm deploying locally. As far as I understood, after I enroll an user all I need is the enrollmentId to call the chaincode, is that correct?

@marcusvs Here are some notes I took from a few months back from a Slack chat...I didn't save the author's name but I suspect it was Gari Singh:
You can enroll a user once as the enrollSecret is a one time password.
- The Node SDK (hfc) and the REST API actually take different paths in how they work
- The NodeSDK will enroll you and download the credentials locally (default is `/tmp/keyValueStore`). At this point, you are enrolled (so you can't enroll again) but your credentials are local to the SDK and now you can only use the SDK to invoke/query as the enrollID you used to enroll
- The REST API works differently. We you call the `/registrar` endpoint via REST, what happens is the the peer actually acts as a "wallet" and enrolls you behind the scenes. So in this case, the credentials end up being stored on the peer itself (by default in the `/var/hyperledge/production/client` directory and in your case this would be inside the Docker container)
so the bottom line is that if you enroll via HFC you can't use the ID via the REST API and vice versa - if you enroll via the REST API you can't use that ID via HFC
silliman
2017-01-27 00:31
@marcusvcs ^^
silliman
2017-01-27 00:32
@marcusvcs and from the same conversation I saved:
Q: is there any difference how certificates are used via HFC and REST?
A: interesting question - the answer is yes and no. With HFC, the certificates are directly used within the hfc code - meaning you'll actually be submitting signed transactions via GRPC to a fabric peer (and technically you could control usages of trasnacaction certificates, etc). When using the REST API, the crypto functions are delegated to the peer to act on your behalf (so you submit a REST call with SecureContext in it and then the peer takes that, converts it into a fabric transaction, signs it with the credentials it is storing on your behalf and then submits it)
So in the end, the system will see the same certificates either way, just that HFC is a more direct and controlled path for a client

2017-01-27 07:55
@thiru The first part of your statement is correct, not sure if the second part is. When you use the REST API, the /registrar endpoint will both register and enroll you. With HFC, I think that you can register a user as a separate call and then later enroll that user. (Of course you can do both at once with the SDK with a call to registerAndEnroll). So, i think what you're asking is, could I take a user that is only registered but not enrolled and use the REST API to finish the enrollment? Not sure- and, furthermore, since the REST API from v0.6 is deprecated and not available in v1.0, you're probably better off focusing on the SDK functionality anyway IMHO.
thiru
2017-01-27 08:00
Thanks for the response silliman.
thiru
2017-01-27 08:02
And one basic question i have is , right now we have a pre defined users mentioned in the memebersrvc.yaml file and i am guessing those users are already registered and we just enroll them to associate with ECert ...
thiru
2017-01-27 08:03
And using HFC we can regsitser new users also, is this assumption right?
silliman
2017-01-27 08:09
Here's my understanding of it. With the REST API, to use /registrar, the user you want to register has to be defined in membersrvc.yaml. But I think that technically that user isn't yet registered, not until you make the /registrar call. It's just that that user has to be in membersrvc.yaml. You can't dynamically define new users with the REST API. With the SDK on the other hand, you can create new users that aren't in membersrvc.yaml. I do believe though that with the SDK the administrative user has to be pre-defined in membersrvc.yaml. E.g. *admin* or *WebAppAdmin* which is typically used in the demo applications. And even though those admin users are pre-defined in membersrvc.yaml, I think you still have to make an SDK call to register them. That's why I don't consider a regular user who is pre-defined in membersrvc.yaml to be registered yet. That definition is just a pre-req for them to get successfully registered.
silliman
2017-01-27 08:17
Here's an analogy, it may not be perfect, but it's how I think about it.... *register* is like inviting somebody to a party. *enroll* is like accepting the invitation to the party. So you can't party until you're registered and enrolled. To take the analogy a step further. *membersrvc.yaml* is like a list of people to invite to the party (i.e., *register*), and the REST API way is kind of saying, I'm only going to invite people who are on that list you've given me, but with the SDK if you're an administrative user, you can invite anybody you want to the party.

as your party grows - can you edit the membersrvcs yaml ? do you have to make any changes to chain code?

We use CA and a client machine can connect to a peer by authorized by CA.

Another question: using HFC nodejs API, it is possible to use the same user in multiples web servers, if I share the keyvalstore, that's right? Can I just copy the files in the keyvalstore to another web server or the servers need to see the exact same file?
garisingh
2017-01-27 13:27
@marcusvcs - sure - multiple instances can use copies of the same keystore
marcusvcs
2017-01-27 13:32
@garisingh so there is no need to synchronize the files, just a one time copy from a server to another will be enough?

silliman
2017-01-27 14:22
conroydave: you can, but I think you'd probably need to restart your membersrvc for it to pick up the new users. I haven't tried this but it should be easy enough for you to test.
garisingh
2017-01-27 14:31
@hl.rose - the PBFT implementation for v0.6 is is under `fabric/consensus`
there is an SBFT implementation of the orderer for v1.0 in the master branch under `fabric/orderer`

it was failing while making orderer peer

no you are not, but currently you’d probably better to get it started using vagrant image

maybe it’s about avoiding to clone the master but instead, try to clone 0.6.1 image
c0rwin
2017-01-27 22:38
Well, master is up to 1.0 version which is currently in dev stage
c0rwin
2017-01-27 22:38
so the manual you’ve just posted not really relevant
matanyahu
2017-01-27 22:38
that’s what I thought
c0rwin
2017-01-27 22:39
this one describes how to work with current `master`
c0rwin
2017-01-27 22:39
to keep using v0.6, yes you need to get 0.6.1 image
matanyahu
2017-01-27 22:41
let me try with 1.0 again
c0rwin
2017-01-27 23:01
@matanyahu run `brew install libtool` on you mac

conroydave

is indexing a feature of fabric? If so, what scenario would you need to reindex?
matanyahu
2017-01-28 09:47
@c0rwin : thanks for explanation, vagrant setup works fine
matanyahu
2017-01-28 09:49
so if I understand well, vagrant setup is a valid devenv installation method for fabric 0.6.1 whereas if I would like to play with 1.0 I need to set it up with docker compose. Is that a correct assumption?
garisingh
2017-01-28 10:34
@matanyahu - if you are not running on Linux, then for v0.6 Vagrant is your best bet (as a matter of fact it's really the only *supported / tested* development environment. With v1.0 (master branch), it's possible to do everything on your host with a few build utilities (e.g. make) , docker and docker-compose (and this is the preferred mechanism moving forward)

@matanyahu: to add to @garisingh, there is, and will likely aways be, a devenv on v1.0 going forward. The main difference is it is now optional.
ghaskins
2017-01-28 18:03
Also, in the near future, what is devenv will likely be reduced to a more simplified setup (e.g. basic xenial + make + docker + compose)
ghaskins
2017-01-28 18:04
but I envision it will continue to be an option for those in which it is less friction to "vagrant up" than it is to get those tools installed
ghaskins

(perhaps windows?)
ghaskins

Has any body implemented pbft successfully on 4 different vm each on different cloud ?
garisingh
2017-01-29 09:31
not sure about different clouds, but we've done it across multiple machines and datacenters. in your private ping you mentioned it works with NOOPs and that's not surprising because in NOOPs there's no requirement for deploy to work on multiple nodes - just the node on which you execute the deploy
garisingh
2017-01-29 09:31
the typical issue is making sure your peer nodes can actually communicate
garisingh
2017-01-29 09:36
1) I'll assume you can externally communicate with each peer - e.g. from your local computer you can reach the `/chain` endpoint(s) on each of your peers
2) If so, can you also check the `/network/peers` endpoint(s) on each peer?

arner
2017-01-29 13:34
@conroydave Using the webAppAdmin user you can register and enroll new users, also if they're not in the membersc.yml. You can find the function to do so in blockchain.js. The user struct in the chaincode is there just to hold the metadata and to link to other structs.

I think this should help: change chain.setRegistrar(”admin"); to chain.setRegistrar(admin);

Hi, I deployed peer server version 0.7.0-snapshot-cb46696 with Vagrant and when I try to register a user from inside a Vagrant VM with the command _peer network login <username>_ , the command fails with an information that there is no such switch as _network_

@thiru it’s a Member: https://github.com/hyperledger/fabric/blob/v0.6/sdk/node/src/hfc.ts#L831. Just put it inside the callback after the chain.enroll function.

I want to install Fabric 0.6 and I followed the readthedocs manual for v0.6. For both vagrant and docker deployments it is suggested to clone the latest repo which obviously is not 0.6 but 1.0 (actually 0.7.0-snapshot-cb46696). The latest master is problematic because it does not seem to have the same commandlets for _peer_
matanyahu
2017-01-29 20:53
so my simple question is: how can I make sure I deploy Fabric 0.6 instead of 1.0, with old style membership services and peer commands such as peer network...etc.
matanyahu
2017-01-29 20:55
my aim is to build a network closest to what is available on bluemix developer account, i.e. 4 nodes + CA. This configuration is well described in $GOPATH/src/github.com.../fabric/bddtests/...docker-compose-4-consensus-bath.yml
arner
2017-01-29 21:01
You could checkout the 0.6 branch, it’s in the repo. Or if it’s just about creating a network the easiest way is to use the official images on Dockerhub or the ones from Yeasy (https://github.com/yeasy/docker-compose-files/tree/master/hyperledger).
matanyahu
2017-01-29 21:04
@arner: thanks for links. I would like to try checking out the 0.6 branch. Can you help me with the url to be used with git clone ?
matanyahu
2017-01-29 21:31
@arner: I used your scripts, they work perfectly fine, thanks!

What is difference between fabric-ca and fabric-cop?
garisingh
2017-01-30 12:42
`fabric-ca` is the new name for the artist formerly known as `fabric-cop`
garisingh
2017-01-30 12:43
and the `fabric-ca` repo is where all the latest development now happens
yuryandreev
2017-01-30 12:45
Thanks. Can we close repo https://github.com/hyperledger/fabric-cop, or change README and description
yuryandreev
2017-01-30 12:46

yuryandreev
2017-01-30 12:48
will be fabric-ca available in v1.0?
pd93
2017-01-30 13:14
@yuryandreev fabric-ca is a pluggable Certificate Authority for fabric. It does not come packaged with v1 (like `membersrvc` did for v0.6). This is so other CA's can be used if needed. Of course, you can use it with v1 though
As for the `cop` repo, It was only discontinued just over a week ago, I imagine the project maintainers will take it down in due course. If not, then I agree. It should have a notice that points people to the new `ca` repo

Let’s imagine a situation: we have a network of 4 commiter-peers, 3 of them approve transaction, but fourth rejects (because it’s hacked by a bad guy), What would be next? Transaction will be rejected?
vadim
2017-01-30 13:52
I guess it’s related to the "fault tolerance” parameter of the SBFT orderer config (https://github.com/hyperledger/fabric/blob/master/orderer/orderer.yaml#L134)
ruslan
2017-01-30 13:53
Yes, but in v1.0 we have no sbft implementation in orderer (but we have a separate app ‘simplebft’)
ruslan
2017-01-30 13:53
…
vadim
2017-01-30 13:54
I see SBFT parameters and config in the orderer
vadim
2017-01-30 13:54
I think it’s implemented
ruslan
2017-01-30 13:58
I see too, but I’ve found this part of code:
switch conf.Genesis.OrdererType {
case ConsensusTypeSolo, ConsensusTypeSbft:
case ConsensusTypeKafka:
bs.minimalItems = append(bs.minimalItems, sharedconfig.TemplateKafkaBrokers(conf.Kafka.Brokers))
default:
panic(fmt.Errorf("Wrong consenter type value given: %s", conf.Genesis.OrdererType))
}

Hello, i have a problem with fabric v0.6. When i make a post with this json :
{
"jsonrpc": "2.0",
"method": "deploy",
"params": {
"type": 1,
"chaincodeID":{
"name":"mycc"
},
"ctorMsg": {
"function":"init",
"args":["a", "1000", "b", "2000"]
},
"secureContext": "lukas"
},
"id": "1"
}
in the json response the status.status is always "OK" .
Also when i add some parameters. Why?
Thanks
cbf
2017-01-30 16:35
@yuryandreev to be clear, fabric-ca will be published concurrently with the other Fabric component images (fabric-peer, fabric-orderer, etc etc) as a set.
ghaskins
2017-01-30 16:44
@cedoor deploy/invoke are async, so what you are seeing is basically a receipt that the peer network accepted your transaction
ghaskins
2017-01-30 16:45
if you want to know if it actually worked, use the events mechanism
bmatsuo
2017-01-30 17:39
@ghaskins ah, events. I was wondering how I would confirm deployment completed without a lot of work. Thanks for the tip.

Hi, I am trying to understand the idea of endorsing transactions by dedicated peers. While the example described in the `https://github.com/hyperledger/fabric/blob/master/proposals/r1/Next-Consensus-Architecture-Proposal.md` document about a required endorser set is quite clear, I wonder if a endorsement logic can for example do such things like (see _chaincode_example0_) "if a value A is even and a value B is odd then return not valid transaction otherwise return valid trans. " ? I am not sure if I correctly interpret the whole idea.

thojest
2017-02-01 09:24
are there any solutions? tried out the comment but didnt work for me
thojest
2017-02-01 09:32
@conroydave hmm what exactly do you mean by that?
pd93
2017-02-01 10:01
@thojest I think @conroydave is suggesting using the IP address when specifying the connection to the peer/membersrvc rather than the host name. eg.. `192.17.0.2:7054` being an IP.. `vp0` / `membersrvc` (`mem` in your example) being a host name. The SO post you linked has a comment that suggests the same thing and worked.
thojest
2017-02-01 10:04
@pd93 so in the docker-compose file you mean this
thojest
2017-02-01 10:05
172.17.0.2:
image: hyperledger/fabric-peer
ports:
- "7050:7050"
- "7051:7051"
environment:
- CORE_PEER_ID=vp0
- CORE_PEER_ADDRESSAUTODETECT=true
- CORE_VM_ENDPOINT=unix:///var/run/docker.sock
- CORE_LOGGING_LEVEL=INFO
command: sh -c "sleep 10; peer node start"
pd93
2017-02-01 10:09
I actually use hostnames and can't seem to replicate this issue, so I'm not sure, but I would suspect it's more referring to links and environment variables.. neither @conroydave or the SO answer specified precisely what to change
I would just try a few combinations. Or start from scratch with a docker-compose that you know works.
thojest
2017-02-01 10:11
@pd93 thx a lot.
thojest
2017-02-01 10:11
im trying combinations for 2 hours now :smile:

2017-02-01 10:12
@pd93 but besides from the hostname thing, my docker-compose file is ok?
thojest
2017-02-01 10:12
or am i doint something completely wrong?
thojest
2017-02-01 10:12
is it a difference if you link A to B or B to A in docker-compose?
thojest
2017-02-01 10:12
am i missing some configurations for membersrvc?
pd93
2017-02-01 10:13
Just having a look at mine now to see any differences (Not that mine is necessarily perfect)
pd93
2017-02-01 10:13
I have links to membersrvc from each peer
thojest
2017-02-01 10:14
ahh ok
thojest
2017-02-01 10:14
but all other peers only have one connection to the root node?
pd93
2017-02-01 10:14
Correct (except the root node itself of course)
thojest
2017-02-01 10:15

why the peer node trying to reach membersrvc on localhost?

@pd93 uploaded a file: https://hyperledgerproject.slack.com/files/pd93/F3ZAAUG0J/compose.zip and commented: This is split into 3 files. A template for peers, a template for the membersrvc and the actual docker-compose which extends from these tempaltes (means less code redundancy)
thojest
2017-02-01 10:26
thanks for the file really helps me alot not only for this problem
thojest
2017-02-01 10:27
is there a differnece between my port mapping and your expose?
pd93
2017-02-01 10:29
`expose`: Expose ports without publishing them to the host machine - they’ll only be accessible to linked services. Only the internal port can be specified.
pd93
2017-02-01 10:30
port mapping is mapping the container port to a port on the host
pd93
2017-02-01 10:31
Also, yeah I spent a long time learning how they work. Those are actually based on the yeasy docker-compose files. Helped me a lot. Especially with the file separation and understanding what each bit did. (Hence the comments)
thojest
2017-02-01 10:32
hmm so when i try to enroll a user
thojest
2017-02-01 10:33
i make a request to the peer node and the peer node communicates with membersrvc?
pd93
2017-02-01 10:35
Yes. You can either do this through the container with the CLI (`docker exec -i <container> /bin/bash && peer network login admin <secret>`) which is directly telling a peer to communicate with membersrvc... or through an SDK. which will redirect your request to one of its connected peers and then to membersrvc
thojest
2017-02-01 10:36
i think the problem i have is the communication between membersrvc and peer
pd93
2017-02-01 10:36
Are you still having the same issue with my compose files?
thojest
2017-02-01 10:37

pd93
2017-02-01 10:37
I won't be using v1 until a release candidate comes out
thojest
2017-02-01 10:43
hmm i get an error and i think that has to do with the verison of the dockerfile
pd93
2017-02-01 10:43
What system are you running docker on?
pd93
2017-02-01 10:43
version of docker etc?
thojest
2017-02-01 10:44
ubuntu 16.04.1
thojest
2017-02-01 10:44
docker-compose version 1.5.2
pd93
2017-02-01 10:45
I'm on Debian 8.6 with docker-compose 1.7.0 and it's running just fine
pd93
2017-02-01 10:46
The deb/ubuntu thing shouldn't be an issue, try updating docker-compose I guess? Not sure what wouldn't work though
thojest
2017-02-01 10:46
i think it has to do with docker version
thojest
2017-02-01 10:48
https://medium.com/@giorgioto/docker-compose-yml-from-v1-to-v2-3c0f8bb7a48e#.30ausrft9 this shows the difference
pd93
2017-02-01 10:49
I think you could just remove the version tag tbh
pd93
2017-02-01 10:50
I don't think there is anything from v2/2.1/3 in there anyway
thojest
2017-02-01 10:50
i think it is like e.g. services
thojest
2017-02-01 10:50
the link you sent me
thojest
2017-02-01 10:50
this compatibility matrix
thojest
2017-02-01 10:50
does the version refer to docker version
thojest
2017-02-01 10:50
or docker-compose verison?
pd93
2017-02-01 10:51
left col is the compose version, the right is the docker version
pd93
2017-02-01 10:51
compose *format* version sorry
pd93
2017-02-01 10:52
So I currently have `docker v1.12.5`, `docker-compose v1.7.0` and that compose file looks pretty v1
thojest
2017-02-01 10:55
YEAHHH
thojest
2017-02-01 10:55

thojest
2017-02-01 10:55

thojest
2017-02-01 10:56
THX a lot !!
pd93
2017-02-01 10:56
Glad it's all working :upside_down_face: No problem
thojest
2017-02-01 10:57
really big thanks for your compose files. they will help me later trying to understand the whole enrollment stuff
pd93
2017-02-01 10:58
If you updated your version of docker/docker-compose, I believe you'd be able to run them with those lines at the top. But tbh they're not really needed seeing as you just proved they will work with older versions
pd93
2017-02-01 10:58
Will probably remove them from mine too :stuck_out_tongue:
thojest
2017-02-01 10:59
:slightly_smiling_face: :+1:
pd93
2017-02-01 11:01
Oh... one other thing to note. I think you said you had security off before? With my docker compose stuff it is very much on :stuck_out_tongue:
thojest
2017-02-01 11:01
@pd93 yeah i noticed that but it isnt a problem. The next step would have been to turn it on and understand how it works. so your files are even a big help for my next step :slightly_smiling_face:

thojest
2017-02-01 12:54
@pd93 so i played a bit with your files and uncommented the security features. then i had the same error like in the beginning. so i undid the uncomment stepwise and i found out that the reason was the following
thojest
2017-02-01 12:55
you have to set CORE_PEER_PKI_ECA_PADDR and CORE_PEER_PKI_TCA_PADDR
thojest
2017-02-01 12:55
i did not specify these in my initial setup
thojest
2017-02-01 12:55
so i guess these things have nothing to do with security enabled, it just tells the peer node where to find membersrvc
pd93
2017-02-01 13:33
@thojest Nice catch :slightly_smiling_face: That didn't even occur to me

i am following the boiler plate API repo - and am using a 3rd party python script to create the user’s and things in the blockchain ledger… i can see them when i open the Node app and log in with one of the test data users. but for some reason when I try to act as newly created user (via my api script) in the Node app - it says the users are not registered and enrolled
conroydave
2017-02-01 22:58
it finds them, just doesnt allow me to act as them
conroydave
2017-02-01 22:59
i am using the add_user, add_thing
conroydave
2017-02-01 23:00
the comment regarding args 0 being the callerid directly above where i just linked is also confusing to me
conroydave
2017-02-01 23:00
i had to change args[1] to args[0] to get it the inserts to work
conroydave
2017-02-01 23:03
do i have somehow have to nodify the Node app that new users have been added to the chain and register them somehow?
conroydave
2017-02-01 23:04
or am i just confused that users in the chain have nothing to do with users in web app

Hi all, I am running fabric v0.6 and i have setup 3 peers vp0, vp1 and vp2. vp0 is root peer. so i have given vp0 address as root peer in vp1 and vp2 docker-compose file. while i query through rest api "/network/peers" from vp0 it shows me 3 peers and if i query from vp1 or v2 it shows only 2 peers i.e. itself and root peer only. Similar if i am invoking chaincode from vp0 then all are in sync but if invoking from another peer i.e. vp1 or vp2 it sync transaction only to itself and root peer only
ankitkamra
2017-02-02 09:27
but logically all nodes must be in sync
ankitkamra
2017-02-02 09:29
can anyone please help me to resolve the problem ??
marcusvcs
2017-02-02 13:53
@conroydave I am no expert, but to act as an user via Node api you have to have the user certificate file in the keyvaluestore folder of your app
marcusvcs
2017-02-02 13:54
If the python script is enrolling the users, it must be placing that file somewhere

quick question: can I create admin users on runtime using the other admin account?
vadim
2017-02-03 11:48
in v0.6 you need to add them to membersrvc.yaml and then restart the service, in v1 (fabric-ca) you can
dsanchezseco
2017-02-03 11:52
in v0.6 is not possible adding the other roles to the delegateRoles field of admin?
vadim
2017-02-03 11:54
I think you are talking about fabric-ca
vadim
2017-02-03 11:54
in v0.6 it’s called membersrvc and it’s managed over yaml file
vadim
2017-02-03 11:55
dsanchezseco
2017-02-03 11:59
yeah, i'll explain myself, i want to create other admin users w/o having to modify the membersrvc and restart the service. So i was wondering if doing something like ` admin: 1 Xurw3yU9zI0l institution_a '{"registrar":{"roles":["client","peer","validator","auditor"],"delegateRoles":["client","peer","validator","auditor"]}}'` on the membersrvc before the first start would abilitate the admin user to create other admins that can create peers, validators and so on?
dsanchezseco
2017-02-03 11:59
or should i wait till v1.0 with the new fabric-ca?
vadim
2017-02-03 12:00
I’m not sure whether v0.6 has this functionality
vadim
2017-02-03 12:00
I’m myself using v1
dsanchezseco
2017-02-03 12:02
which is the estimate release date of v1.0?
vadim
2017-02-03 12:02
I think alpha version should be quite soon
vadim
2017-02-03 12:02
but you can already use it, just the documentation is not very structured
dsanchezseco
2017-02-03 12:06
that has never been a problem hahahahaha we all know the blockchain's docs
vadim
2017-02-03 12:06
well then just use v1 :slightly_smiling_face:
garisingh
2017-02-03 12:06
@dsanchezseco - even in v0.6 you can add users and new admins
garisingh
2017-02-03 12:07
if you checkout the NodeSDK, you'll see some test files (something like *registrar*.js)
garisingh
2017-02-03 12:07
which show how to add new users/admins to membersrvcs
thojest
2017-02-03 12:22
hmm when i try to use grpcs for hfc sdk where do i get the certificates
dsanchezseco
2017-02-03 12:25
@garisingh can you post the URL because on https://github.com/hyperledger/fabric-sdk-node only seems to be code for v1
dsanchezseco
2017-02-03 12:27
nevermind, found through stackoverflow https://github.com/hyperledger/fabric/blob/ceefb12425b7ccb09fc0f88dc78d395a459dca55/sdk/node/test/unit/registrar.js
dsanchezseco
2017-02-03 12:32
well, i have the same doubt what should i do to register and enroll another admin user whit something like this ```// STEP 2: Register and enroll webAdmin and set as register
function registrarTestStep2(cb) {
console.log("registrarTest: STEP 2");
registerAndEnroll("webAdmin", "client", null, {roles:['client']}, chain, function(err,user) {
if (err) return cb(err);
webAdmin = user;
chain.setRegistrar(webAdmin);
registrarTestStep3(cb);
});
}```
instead of WebAppAdmin able to create only clients be able to create another admins.
dsanchezseco
2017-02-03 12:32
something like this:
dsanchezseco
2017-02-03 12:34
admin -> admin2 ->client
| |->admin4
|
|->admin3 -> peer
|->peer
|-> client
garisingh
2017-02-03 12:58
`{roles:['client']}` means that you are registering webAdmin and granting webAdmin the authority to register other clients
dsanchezseco
2017-02-03 12:58
so if i fill that with other roles i'll be able to create them right?
dsanchezseco
2017-02-03 12:59
can you explain more in depth delegateRoles? is not fully clear on the comments
garisingh
2017-02-03 13:52
@dsanchezseco - been a while since I looked at this stuff. But yes - if you add additional types to the "roles", then the user will be able to register users with those roles
garisingh
2017-02-03 13:54
delegateRoles is used to indicate which roles that user can specify in the "roles" field when registering additional users
garisingh
2017-02-03 13:54
Put another way, if you don't have any delegateRoles, it means that when you register users, you will not be able to grant those users the right to register other users

I am currently testing tx performance on Fabric 0.6 with Example02 chaincode. I created a bash script that executes a loop chaincode invoke command for 1000 times. I copied that script on 4 nodes, deployed in a PBFT-compliant mode (4 VPs + 1 membership service node). Here are my results: *Avg. Txn Latency 45ms Transaction Rate 15 /sec Mining Rate 8blocks/sec* . Has anyone got anything better than that?

Hello everyone, I've been trying to run a hyperledger setup in windows & linux. In windows using Docker-compose, my question is what are the commands/settings to register my chaincode?

@spiro : the best way is to deploy a clean docker environment just by pulling stable images from docker hub
matanyahu
2017-02-04 20:17
then, execute docker-compose with a selected topology
matanyahu
2017-02-04 20:18
and then, log in to one of VPs and deploy chaincode either as REST API or with peer chaincode deploy command
matanyahu
2017-02-04 20:18
that's what I do and I do not use the newest master
matanyahu
2017-02-04 20:19
images from docker hub dating back from 3 months ago are fair enough for me, especially that I want to have an environment identical to the one used on IBM Bluemix (0.6.1)

after you select your docker-compose topology and run your network

I now assume "docker exec -it vp0_1 bash
matanyahu
2017-02-04 20:27
log in to one of your containers representing one of peers deployed by docker-compose sscript
matanyahu
2017-02-04 20:28
and then you can start sending commands locally (peer cmdlets or REST API curl cmdlets against 0.0.0.0:7050)
matanyahu
2017-02-04 20:28
or from your workstation you can send commands remotely if you know your containers ip addresses

@garisingh hey, could you please check out the errors i've been getting with running the boilerplate?

hi! Does the `membersrvc` need to be the only instance for the whole network (like in `four-peer-ca.yaml` example)? Or may each node has its own copy of `membersrvc` provided they all have the same config?
karnn
2017-02-06 13:48
@sibelius i'll check it out once i figure out whats up with my setup. thanks.

I'm trying to get a clear overview of how the consensus process works in Fabric but I'm not finding the answer to my question in the documentation. I am assuming nodes verify and sign blocks in a round-robin fashion? And that these signatures are counted by each nodes before adding a block to their own chain? Where can I get a detailed description of that process? Sorry if my assuming is completely off

@abhinav.garg you can find a few demos (the ones you excluded + commercial paper) on the bluemix platform if you follow the link: https://console.ng.bluemix.net/docs/services/blockchain/ibmblockchain_tutorials.html

Try repeating the question on the new chat platform. You might get other replies over there.

Hello, I am playing with HL from master branch and when I try to make a invocation request to peer i receive gRPC error:
code = 2 desc = Failed to deserialize creator identity, err MSP admin is unknown
User admin is enrolled from CA and has proper cert
I am using docker images and docker-compose from https://github.com/hyperledger/fabric/blob/master/docs/gettingstarted.md
Any idea what may cause MSP not to find user admin (or any other user)
When i do invocation from CLI everything is working properly.

hi everyone, following question considering Hyperledger v 0.6
When I create a webapp and I want to handle user login, how would i do that? afaik there are several security layers
thojest
2017-02-07 13:44
1)webapp
2) membersrvc
3) blockchain
thojest
2017-02-07 13:47
So if the user wants to login is this the best way of doing this???
- take username and password
- encrypt passwords and sends details to chaincode
- chaincode checks that encrypted passwords match
- If correct send, success message back to node
- node then enrols the user so that the app can send transactions as the user with the returned cert
- It also creates a session so that it knows it is allowed to use the cert.
thojest
2017-02-07 13:47
what confuses me is the following point
thojest
2017-02-07 13:48
I thought membesrvc manages all this user authentification stuff?
thojest
2017-02-07 13:49
do i have to write user + hash(password) to the blockchain?

i was reading about 3 types of nodes... consenter, etc. could you give me more background information. How do I know what type of node my peers are, or how can I configure that? I also heard about an orderer node
